In a recent publication in Physical Review D, HITS researchers Friedrich Röpke and Sebastian Ohlmann were part of a team around Warren Wright from North Carolina State University to compare the neutrino output of different scenarios of Type Ia supernovae. These are explosions of white dwarf stars; however, the detailed progenitor systems and explosion mechanisms remain elusive. In this paper, neutrino signals for future neutrino detectors are computed and corresponding observations will help to discriminate between the different scenarios.
This work was reported as a research highlight in Nature.

The Heidelberg Institute for Theoretical Studies (HITS) was established in 2010 by the physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural sciences, mathematics and computer science, with a focus on the processing, structuring, and analyzing of large amounts of complex data and the development of computational methods and software. The research fields range from molecular biology to astrophysics. The shareholders of HITS are the HITS-Stiftung, which is a subsidiary of the Klaus Tschira Foundation, Heidelberg University and the Karlsruhe Institute of Technology (KIT). HITS also cooperates with other universities and research institutes and with industrial partners. The base funding of HITS is provided by the HITS Stiftung with funds received from the Klaus Tschira Foundation. The primary external funding agencies are the Federal Ministry of Education and Research (BMBF), the German Research Foundation (DFG), and the European Union.
