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.

HITS, the Heidelberg Institute for Theoretical Studies, was established in 2010 by 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, mathematical, and computer sciences. Major research directions include complex simulations across scales, making sense of data, and enabling science via computational research. Application areas range from molecular biology to astrophysics. An essential characteristic of the Institute is interdisciplinarity, implemented in numerous cross-group and cross-disciplinary projects. The base funding of HITS is provided by the Klaus Tschira Foundation.
