Because calibrated light curves of Type Ia supernovae have become a major tool to determine the local expansion rate of the Universe and also its geometrical structure, considerable attention has been given to models of these events over the past couple of years. There are good reasons to believe that perhaps most Type Ia supernovae are the explosions of white dwarfs that have approached the Chandrasekhar mass, M_ch ~ 1.39 M_sun, and are disrupted by thermonuclear fusion of carbon and oxygen. However, the mechanism whereby such accreting carbon-oxygen white dwarfs explode continues to be uncertain. Recent progress in modeling Type Ia supernovae as well as several of the still open questions are addressed in this review. Although the main emphasis will be on studies of the explosion mechanism itself and on the related physical processes, including the physics of turbulent nuclear combustion in degenerate stars, we also discuss observational constraints.

Optical observations on the young Type Ia SN 2021fxy with detached high velocity features
In SN 2021fxy, the high-velocity Si II λ6355 absorption declines as roughly t^−0.1, much shallower than the t^−0.22 expected from standard outer ejecta, pointing to detached density structures.

Ambiguity in matter sector for modified gravity involving $\delta^2 \mathcal{L}_{m}/\delta g^{\mu\nu}\delta g^{\alpha\beta}$ and its implications to astrophysics and cosmology
The paper claims that enforcing four-velocity normalization makes modified-gravity field equations independent of the matter-Lagrangian choice, with illustrative compact-star and cosmology results.
