Despite the importance of Type Ia supernovae (SNe Ia) for modern astrophysics, their detailed mechanism is still not fully understood. In this contribution, we present recent findings from numerical explosion models in the context of the observed diversity of SNe Ia and we discuss how these models can help to shed light on the explosion mechanism and the progenitor stars of SNe Ia. In addition, we introduce the Heidelberg Supernova Model Archive (HESMA), a new online data base where we provide integrated isotopic abundances and radially averaged ejecta profiles and synthetic observables for a wide range of state-of-the-art explosion models.

  1. SEDONA-GesaRaT: an AI-Accelerated Radiative Transfer Program for 3-D Supernova Simulations

    astro-ph.HE 2025-07 conditional novelty 6.0 of 10

    A neural-network surrogate for non-LTE atomic physics enables 3D supernova radiative transfer and spectropolarimetry at roughly 3000 core-hours.

  2. Effect of positronium on the $\gamma$-ray spectra and energy deposition in Type Ia supernovae

    astro-ph.HE 2025-05 conditional novelty 5.0 of 10

    If all positrons form positronium before annihilation in Type Ia supernova ejecta, the 511 keV gamma-ray line flux decreases by about 70 percent and energy deposition increases by up to 2 percent near 100 days.
