The observed sub-class of “superluminous” Type Ia supernovae lacks a convincing theoretical explanation. If the emission of such objects were powered exclusively by radioactive decay of 56Ni formed in the explosion, a progenitor mass close to or even above the Chandrasekhar limit for a non-rotating white dwarf star would be required. Masses significantly exceeding this limit can be supported by differential rotation. We, therefore, explore explosions and predict observables for various…

A Carbon/Oxygen-dominated Atmosphere Days after Explosion for the “Super-Chandrasekhar” Type Ia SN 2020esm

Seeing pristine material from the donor star in a type Ia supernova (SN Ia) explosion can reveal the nature of the binary system. In this paper, we present photometric and spectroscopic observations

Can the Violent Merger of White Dwarfs Explain the Slowest Declining Type Ia Supernova SN 2011aa?

We present optical observations and Monte Carlo radiative transfer modeling of the Type Ia supernova (SN Ia) SN 2011aa. With a Δm 15(B) of 0.59 ± 0.07 mag and a peak magnitude M B of −19.30 ± 0.27

Spectral Sequences of Type Ia Supernovae. II. Carbon as a Diagnostic Tool for Explosion Mechanisms

How an otherwise inert carbon–oxygen white dwarf can be made to explode as an SN Ia remains unknown. A promising test of theoretical models is to constrain the distribution of material that is left

Accretion-induced Collapse of Dark Matter Admixed White Dwarfs. II. Rotation and Gravitational-wave Signals

We present axisymmetric hydrodynamical simulations of accretion-induced collapse (AIC) of dark matter (DM) admixed rotating white dwarfs (WD) and their burst gravitational-wave (GW) signals. For

Although type Ia supernovae (SNe Ia) are so important in many astrophysical fields, a debate on their progenitor model is still endless. Searching the surviving companion in a supernova remnant (SNR)

Probabilistic Reconstruction of Type Ia Supernova SN 2002bo

Manual fits to spectral times series of Type Ia supernovae have provided a method of reconstructing the explosion from a parametric model but due to lack of information about model uncertainties or

Light Curves of Type Ia Supernovae

Abstract We have studied the light curves of type Ia supernovae (SNe Ia) and the physical parameters inferred from them. We have constructed both analytical and numerical light curves of SNe Ia.

The dependence of Type Ia Supernovae salt2 light-curve parameters on host galaxy morphology

Type Ia Supernovae (SNe Ia) are widely used to measure distances in the Universe. Despite the recent progress achieved in SN Ia standardization, the Hubble diagram still shows some remaining

ASASSN-15pz: Revealing Significant Photometric Diversity among 2009dc-like, Peculiar SNe Ia

We report comprehensive multi-wavelength observations of a peculiar Type Ia-like supernova (“SN Ia-pec”) ASASSN-15pz. ASASSN-15pz is a spectroscopic “twin” of SN 2009dc, a so-called

Dalek: A Deep Learning Emulator for TARDIS

This work presents an emulator for the tardis supernova radiative transfer code applied to Type Ia supernova spectra and shows an accuracy on the percent level with a speedup of several orders of magnitude.



Thermonuclear explosions of rapidly rotating white dwarfs - I. Deflagrations

Context. Turbulent deflagrations of Chandrasekhar mass white dwarfs are commonly used to model type Ia supernova explosions. In this context, rapid rotation of the progenitor star is plausible but

Deflagrations in hybrid CONe white dwarfs: a route to explain the faint Type Iax supernova 2008ha

Stellar evolution models predict the existence of hybrid white dwarfs (WDs) with a carbon-oxygen core surrounded by an oxygen-neon mantle. Being born with masses similar to 1.1 M-aS (TM), hybrid WDs

On the evolution of rapidly rotating massive white dwarfs towards supernovae or collapses

A recent study indicated that the inner cores of rapidly accreting (M > 10 -7 M ○. yr -1 ) CO white dwarfs may rotate differentially, with a shear fate near the threshold value for the onset of the

The Thermonuclear Explosion of Chandrasekhar Mass White Dwarfs

The flame born in the deep interior of a white dwarf that becomes a Type Ia supernova is subject to several instabilities, the combination of which determines the observational characteristics of the

The type Ia supernova SNLS-03D3bb from a super-Chandrasekhar-mass white dwarf star

It is shown that the high-redshift supernova SNLS-03D3bb has an exceptionally high luminosity and low kinetic energy that both imply a super-Chandrasekhar-mass progenitor, which may provide an explanation for the observed trend that overluminous type Ia supernovae occur only in ‘young’ environments.


In the double-detonation scenario for Type Ia supernovae, it is suggested that a detonation initiates in a shell of helium-rich material accreted from a companion star by a sub-Chandrasekhar-mass
