All known Type Ia supernovae models fail to reproduce the observed bolometric luminosity-width correlation
Amir Sharon, Doron Kushnir, Nahliel Wygoda
Type Ia supernovae (SNe Ia) are widely believed to arise from thermonuclear explosions of white dwarfs (WDs). However, ongoing debate surrounds their progenitor systems and the mec…

Sub-Chandrasekhar-mass detonations are in tension with the observed relation of type Ia supernovae
Doron Kushnir, Nahliel Wygoda, Amir Sharon
Type Ia supernovae (SNe Ia) are likely the thermonuclear explosions of carbon-oxygen (CO) white-dwarf (WD) stars, but their progenitor systems remain elusive. Recent studies have s…

Type Ia supernovae have two physical width-luminosity relations and they favor sub-Chandrasekhar and direct collision models - II. Color evolution
Nahliel Wygoda, Boaz Katz, Yonatan Elbaz
While the width-luminosity relation (WLR) among type Ia supernovae (slower is brighter) is one of the best studied properties of this type of events, its physical basis has not bee…
