SN 2010lp---a Type Ia supernova from a violent merger of two carbon--oxygen White Dwarfs
M. Kromer, R. Pakmor, S. Taubenberger +6
SN 2010lp is a subluminous Type Ia supernova (SN Ia) with slowly-evolving lightcurves. Moreover, it is the only subluminous SN Ia observed so far that shows narrow emission lines o…
Predicting the amount of hydrogen stripped by the supernova explosion for SN 2002cx-like SNe Ia
Zheng-Wei Liu, M. Kromer, M. Fink +5
The most favored progenitor scenarios for Type Ia supernovae (SNe Ia) involve the single-degenerate (SD) scenario and the double-degenerate scenario. The absence of stripped hydrog…
Solar abundance of manganese: a case for the existence of near Chandrasekhar-mass Type Ia supernova progenitors
Ivo R. Seitenzahl, Gabriele Cescutti, Friedrich K. Roepke +2
Context: Manganese is predominantly synthesised in Type Ia supernova (SN Ia) explosions. Owing to the entropy dependence of the Mn yield in explosive thermonuclear burning, SNe Ia…
Cosmological Parameter Estimation from SN Ia data: a Model-Independent Approach
S. Benitez-Herrera, E. E. O. Ishida, M. Maturi +4
We perform a model independent reconstruction of the cosmic expansion rate based on type Ia supernova data. Using the Union 2.1 data set, we show that the Hubble parameter behaviou…
Synthetic light curves and spectra for three-dimensional delayed-detonation models of Type Ia supernovae
S. A. Sim, I. R. Seitenzahl, M. Kromer +7
In a companion paper, Seitenzahl et al. (2013) presented a set of three-dimensional delayed detonation models for thermonuclear explosions of near-Chandrasekhar mass white dwarfs (…
Three-dimensional pure deflagration models with nucleosynthesis and synthetic observables for Type Ia supernovae
M. Fink, M. Kromer, I. R. Seitenzahl +6
We investigate whether pure deflagration models of Chandrasekhar-mass carbon-oxygen white dwarf stars can account for one or more subclass of the observed population of Type Ia sup…
A Subgrid-scale Model for Deflagration-to-Detonation Transitions in Type Ia Supernova Explosion Simulations - Numerical implementation
F. Ciaraldi-Schoolmann, I. R. Seitenzahl, F. K. Roepke
A promising model for normal Type Ia supernova (SN Ia) explosions are delayed detonations of Chandrasekhar-mass white dwarfs, in which the burning starts out as a subsonic deflagra…
The impact of Type Ia supernova explosions on helium companions in the Chandrasekhar-mass explosion scenario
Zheng-Wei Liu, Ruediger Pakmor, Ivo Seitenzahl +8
In the version of the SD scenario of SNe Ia studied here, a CO WD explodes close to the Chandrasekhar limit after accreting material from a non-degenerate He companion. In the pres…
The Effects of Variations in Nuclear Interactions on Nucleosynthesis in Thermonuclear Supernovae
Anuj Parikh, Jordi Jose, Ivo R. Seitenzahl +1
The impact of nuclear physics uncertainties on nucleosynthesis in thermonuclear supernovae has not been fully explored using comprehensive and systematic studies with multiple mode…
Combustion of a neutron star into a strange quark star: The neutrino signal
G. Pagliara, M. Herzog, F. K. Roepke
There are strong indications that the process of conversion of a neutron star into a strange quark star proceeds as a strong deflagration implying that in a few milliseconds almost…
Gamma-ray diagnostics of Type Ia supernovae: Predictions of observables from three-dimensional modeling
A. Summa, A. Ulyanov, M. Kromer +11
Besides the fact that the gamma-ray emission due to radioactive decays is responsible for powering the light curves of Type Ia supernovae (SNe Ia), gamma rays themselves are of par…
