MINT EC Camp on Astrophysics at TU Dresden

From May 5 to 8, 2025, 24 students from the national excellence school network MINT-EC were hosted as guests at the TUD Dresden University of Technology. As part of a four-day camp on astrophysics, they gained exciting insights into current research into the physics of stars.

Together with scientists from the Institute of Nuclear and Particle Physics (IKTP) at TU Dresden and the Helmholtz-Zentrum Dresden-Rossendorf, the young people explored key questions in astrophysics. The focus was on experiments and theories on the formation of chemical elements and the development of stars. In hands-on workshops, they analyzed experimental data – for example with measurement data from the underground laboratory “Felsenkeller”, which they visited as part of the camp. There they experienced how particle accelerators are used to research processes that take place deep inside stars. The camp concluded with a presentation of the young people’s own initial research findings, which they develop over the four days.

Getting to know Dresden as a place to study is also part of the program. During a campus tour, the participants gained an insight into life and learning at TU Dresden. In the evening, they explored Dresden’s Neustadt district together with students.

The camp participants were selected from 140 applications from MINT-EC schools throughout Germany. One student traveled from the German School Quito in Equador to Dresden to take part in the astrophysics camp.

The astrophysics camp took place at a particularly exciting time: The German Center for Astrophysics (DZA) is currently being built in Lusatia – with the cooperation of TU Dresden. The young people thus experienced research at the cutting edge of a highly innovative field of science with great future prospects.

Second ChETEC-INFRA Observational School held in Prague

The second ChETEC-INFRA Observational School (ChINOS2) took place in Prague from 21 to 25 July, hosted by the Academy of Sciences of the Czech Republic at its representative residence, Villa Lanna.

Twenty students from eleven countries attended lectures and undertook hands-on spectroscopic work. They also undertook spectroscopic work during the day. They observed remotely at night. Working hours ranged from 12 to 18 hours per day (9am to 3am).

For the observations, we had access to the Nordic Optical Telescope on La Palma in Spain. Participants had the opportunity to visit the Ondřejov Observatory and the Perek Telescope, which is one of the TA instruments within the ChETEC-INFRA project.

The school was co-sponsored by ChETEC-INFRA and the German Centre for Astrophysics. The Astronomical Institute of the Czech Academy of Sciences (ASU) acted as the host institution.

Registration Open for 5th General Assembly and TA User Meeting in Dresden

The fifth and final ChETEC-INFRA General Assembly will be held in Dresden on September 17 and 18, 2025. Following previous Assemblies and Transnational Access User Meetings – online, in Padua, in Debrecen, and in Strasbourg – the program will feature progress reports from within the project, and scientific talks on recent developments in nuclear astrophysics. The Transnational Access User Meeting provides a forum for exchange between TA users and facilities, and to highlight TA projects realized within ChETEC-INFRA.

Participant registration is open. Abstract submission and applications for financial support are requested until May 12, 2025.

“Stelle sulla Terra”: Nuclear Astrophysics Outreach made Accessible

ChETEC-INFRA supports the project “Stars on Earth – Inclusive dissemination paths of Nuclear Astrophysics”. Founded at the Department of Physics and Astronomy of the University of Padua, the project pursues the goal to broaden the target audience of scientific dissemination activities through the development of inclusive methods of communication, adopting techniques to improve accessibility of scientific outreach for people with disabilities, in particular for people with visual or hearing impairments.

The topic of Nuclear Astrophysics fascinates scientists and the general public alike: The chemical elements that constitute the world around us were created in stars. Surprisingly, to study the origin of the elements does involve laboratories not in space, but on Earth – some of them even located underground to be shielded from disturbances reaching the Earth from space. The project includes the development of several integrated tools, such as the creation of a tactile scale model of the new Bellotti Ion Beam Facility (located in the underground laboratories of Gran Sasso), which are accompanied by activities and multimedia material for further information.

Registration Open for 2nd ChETEC-INFRA Observational School

We are delighted to announce the 2nd ChETEC-INFRA Observational School (“ChINOS2”). This school will bring together Master’s students, PhD students and young postdocs who want to learn about the thrills and challenges of stellar spectroscopic observations, analysis and interpretation from experts in the field.

To this end, we have secured 4 half nights with the Nordic Optical Telescope, which we will operate remotely from Prague. Lectures and hands-on sessions will cover observation preparations including archival searches (e.g. HST, Gaia), spectroscopic data analysis with webSME, stellar atmospheric modelling (classical, 3D and NLTE), chemical evolution modelling, scientific writing (tbc). Students will develop their own stellar science project in small teams.

The school is supported by the German Center for Astrophysics and ChETEC-INFRA.

Registration is now open on the School Web Page, available until April 30.

Interdisciplinary Physics of the Sun

Spanish‐German WE-Heraeus-Seminar

Date: 29 Jun – 04 Jul 2025
Location: Physikzentrum Bad Honnef, Germany

Scientific organizers:
Prof. Dr. Daniel Bemmerer, HZDR Dresden‐Rossendorf • Prof. Dr. Markus Roth, Thüringer Landessternwarte Tautenburg • Dr. Aldo Serenelli, ICE, CSIC Cerdanyola del Valles/E

The physical understanding of our Sun is in many ways foundation science. Its applications range from the Sun as a calibrated neutrino source, as a laboratory for reactions and decays of light nuclei under plasma conditions and for magnetohydrodynamical processes, to its function as a benchmark for stellar models: Stellar structure, evolution, and seismology can be precisely tested against data from the well-observed Sun. Advanced telescopes and space missions aided by theoretical modelling study the processes that are involved in the continuous reconfiguration of the Sun’s magnetic field on the surface and the atmosphere. A continuous solar wind of particles fills interplanetary space, while coronal mass ejections lead to solar storms, posing risks to technology in near-Earth space or on ground. A large number of space missions have advanced our knowledge on the Sun and its influence on the planetary system. Scientists in Germany and Spain have for many years been at the forefronts both of the physics of the solar core (neutrinos and nuclear reactions) and phenomena from the solar interior via the surface to the solar wind. However, these research fields have developed and prospered largely in parallel, with limited interaction.

The present workshop aims to bridge this gap and assemble a core group of scientists working on all physical aspects of the Sun. The main concepts of each branch of solar research shall be laid out in dedicated lectures. There shall be ample space for free discussion, with the aim of discovering new interdisciplinary research avenues to address the Interdisciplinary Physics of the Sun.

The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.

Professor Evgeni Hristov Semkov

The ChETEC-INFRA scientific community and consortium announce with great sadness the passing of its General Assembly member and PI of the ChETEC-INFRA infrastructure at the Rozhen telescope, Professor Evgeni Hristov Semkov, on December 29, 2024, after a brief illness.

Evgeni Semkov graduated from Sofia University “St. Kliment Ohridski” in Bulgaria with a degree in astronomy. He earned his PhD in 1994 and his Doctor of Science (DSci) degree in 2023. His main research focus was the study of young stellar objects, and he successfully supervised four PhD students in this field.

From 2016 until his passing, Prof. Semkov served as the Director of the Institute of Astronomy with the National Astronomical Observatory (NAO). During his tenure, he spearheaded the construction of a new 1.5-meter telescope at NAO-Rozhen, a major scientific infrastructure project under the National Science Infrastructure Roadmap, which is now fully operational.

Prof. Semkov’s outstanding contributions to science were widely recognized. He was honored with the Award for High Scientific Achievements during the competition commemorating the 145th anniversary of the Bulgarian Academy of Sciences and received the prestigious 2024 Pythagorean Prize. In the same year, he was elected a Corresponding Member of the Bulgarian Academy of Sciences, marking a significant acknowledgment of his exceptional scientific accomplishments.

Prof. Semkov was deeply committed to the field of astronomy. Known for his openness to new ideas, readiness to assist others, and unwavering support for young scientists, he was a beloved figure in the astronomical community. With his passing, Bulgaria has lost one of its most prominent representatives in the field of astronomy.
