Helium in Double-Detonation Models of Type Ia Supernovae
Aoife Boyle, Stuart A. Sim, Stephan Hachinger +1
The double-detonation explosion model has been considered a candidate for explaining astrophysical transients with a wide range of luminosities. In this model, a carbon-oxygen whit…
Spectropolarimetry of superluminous supernovae: insight into their geometry
C. Inserra, M. Bulla, S. A. Sim +1
We present the first spectropolarimetric observations of a hydrogen-free superluminous supernova at z=0.1136, namely SN 2015bn. The transient shows significant polarization at both…
Diffuse Galactic antimatter from faint thermonuclear supernovae in old stellar populations
Roland M. Crocker, Ashley J. Ruiter, Ivo R. Seitenzahl +10
Our Galaxy hosts the annihilation of a few low-energy positrons every second. Radioactive isotopes capable of supplying such positrons are synthesised in stars, st…
Three-dimensional simulations of gravitationally confined detonations compared to observations of SN 1991T
Ivo R. Seitenzahl, Markus Kromer, Sebastian T. Ohlmann +9
The gravitationally confined detonation (GCD) model has been proposed as a possible explosion mechanism for Type Ia supernovae in the single-degenerate evolution channel. Driven by…
The peculiar Type Ia supernova iPTF14atg: Chandrasekhar-mass explosion or violent merger?
M. Kromer, C. Fremling, R. Pakmor +11
iPTF14atg, a subluminous peculiar Type Ia supernova (SN Ia) similar to SN 2002es, is the first SN Ia for which a strong UV flash was observed in the early-time light curves. This h…
The type Iax supernova, SN 2015H: a white dwarf deflagration candidate
M. R. Magee, R. Kotak, S. A. Sim +22
We present results based on observations of SN 2015H which belongs to the small group of objects similar to SN 2002cx, otherwise known as type Iax supernovae. The availability of d…
