PSO group releases the Heidelberg Supernova Model Archive

30. June 2017

The PSO group is pleased to announce the release of the Heidelberg Supernova Model Archive (HESMA). HESMA currently includes data on about 70 Type Ia supernova explosion models.The models cover a wide range of progenitor scenarios and explosion mechanisms of Type Ia supernovae and were produced by the PSO group at HITS and its collaborators at the Max Planck Institute for Astrophysics in Garching, Queen’s University Belfast (UK), and UNSW Canberra (Australia). Future models from this collaboration will be added to HESMA after publication.

HESMA provides integrated isotopic abundances as well as radially averaged density and isotopic abundance profiles of the explosion ejecta after they achieved homologous expansion. It also offers angle-averaged UVOIR bolometric light curves and gamma-ray and optical spectral time series. Bolometric light curves are tabulated from ~ 6 to 80 d past explosion. Gamma-ray spectra for selected models are available from ~ 6 to 100 d past explosion. Optical (λ ϵ [3500,9500] Å) spectral time series are available from ~ 6 to 40 d past explosion.

We hope that the data will be useful for a wide part of the astrophysical community from supernova modelling over the interpretation of observed supernova spectra to galactic and cosmic chemical evolution.

About HITS

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.
