Type Ia supernovae from sub-Chandrasekhar mass white dwarfs
, 2016 We argue that detonations of sub-Chandrasekhar mass white dwarfs can lead to bright explosions with light curves and spectra similar to those of observed Type Ia supernovae.

Explosion Parameters of SN 2013df and Properties of Its Progenitor Star [PDF]
, 2014 Type IIb supernovae have only recently been identified as a distinct flavor of core-collapse stellar explosions. These supernovae represent a transitional type between Type II and Type Ib supernovae.

SN 2021hpr: A Normal Type Ia Supernova Showing Excess Emission in the Early Rising Phase
The Astrophysical JournalWe present extensive optical observations of a nearby Type Ia supernova (SN Ia), SN 2021hpr, located in the spiral galaxy NGC 3147 at a distance of ∼45 Mpc. Our observations cover a phase within ∼1–2 days to ∼290 days after the explosion.

The Peculiar Type Ia Supernova 2005hk [PDF]
AIP Conference Proceedings, 2007 We present a preliminary analysis of an extensive set of optical observations of the Type Ia SN 2005hk. We show that the evolution of SN 2005hk closely follows that of the peculiar SN 2002cx. SN 2005hk is more luminous than SN 2002cx, while still under-luminous compared to normal Type Ia supernovae. The spectrum at 9 days before maximum is dominated by

, 2012 Supernovae are some of the brightest and most energetic explosions in the universe. In the mid- to late-twentieth century, it was discovered that Type Ia supernovae, the brightest and most homogeneous subtype, are a different breed from the rest ...

The Astrophysical Journal, 2023 We present multiwavelength time-series spectroscopy of SN 2013aa and SN 2017cbv, two Type Ia supernovae (SNe Ia) on the outskirts of the same host galaxy, NGC 5643. This work utilizes new nebular-phase near-infrared (NIR) spectra obtained by the Carnegie

TYPE Ia SUPERNOVA CARBON FOOTPRINTS [PDF]
The Astrophysical Journal, 2011 We present convincing evidence of unburned carbon at photospheric velocities in new observations of 5 Type Ia supernovae (SNe Ia) obtained by the Nearby Supernova Factory. These SNe are identified by examining 346 spectra from 124 SNe obtained before +2.5 d relative to maximum.

Type Ia Progenitor Hunt in Ancient Remains
, 2016 There is broad agreement that the stars which explode as Type Ia supernovae are white dwarfs. They have accreted material in a binary system until they are near the Chandrasekhar mass and detonate/deflagrate.
