Type Iax supernovae as a source of iron-rich silicate dust
Aman Kumar, Arkaprabha Sarangi
We model the formation of dust in the ejecta of Type Iax supernovae (SNe), which is a low-luminosity subclass of Type Ia SNe. A non-equilibrium chemical kinetic approach is adopted…
Radial dust distributions and obscuring geometry in AGN from JWST/MIRI spectroscopy
Ruiyu Pan, Arkaprabha Sarangi
The spatial distribution of obscuring dust in active galactic nuclei (AGN) is critical for distinguishing between static torus models and dynamical disk-wind scenarios. To constrai…
Stochasticity in Stellar Yields Reflected in Supernova Dust Masses Across All Massive-Star Progenitors
Archana Purushothaman, Arkaprabha Sarangi, S. K. Jeena
Massive stars, ending their lives as supernovae (SNe), are among the primary sources of dust in galaxies. In this study, we derive theoretical upper limits on dust masses as a func…
Radiative-transfer models for dusty Type II supernovae
Luc Dessart, D. John Hillier, Arkaprabha Sarangi
Dust is expected to form on a year timescale in core-collapse supernova (SN) ejecta. Its existence is revealed through an infrared brightening, an optical dimming, or a blue-red em…
