Hydrodynamical modelling of Type IIb SNe
Mattias Ergon, Maximilian Stritzinger, Francesco Taddia +2
We present HYDE, a new one-dimensional hydrodynamical code, and use it to construct a grid of supernova (SN) models based on solar-metallicity bare helium-core models evolved to th…
Three-component modelling of O-rich AGB star winds I. Effects of drift using forsterite
C. Sandin, L. Mattsson, K. L. Chubb +2
Stellar winds of cool and pulsating asymptotic giant branch (AGB) stars enrich the interstellar medium with large amounts of processed elements and various types of dust. We presen…
Spectral modelling of Type IIb Supernovae
Mattias Ergon, Claes Fransson
We use the new NLTE lightcurve and spectral synthesis code JEKYLL to evolve a macroscopically mixed ejecta model of a type IIb Supernova (SN) originating from a star with an initia…
Monte-Carlo methods for NLTE spectral synthesis of supernovae
M. Ergon, C. Fransson, A. Jerkstrand +3
We present JEKYLL, a new code for modelling of supernova (SN) spectra and lightcurves based on Monte-Carlo (MC) techniques for the radiative transfer. The code assumes spherical sy…
The Type IIn Supernova 2010bt: The Explosion of a Star in Outburst
N. Elias-Rosa, S. D. Van Dyk, S. Benetti +12
It is well known that massive stars (M > 8 M_sun) evolve up to the collapse of the stellar core, resulting in most cases as a supernova (SN) explosion. Their heterogeneity is relat…
Did the progenitor of SN2011dh have a binary companion?
J. R. Maund, I. Arcavi, M. Ergon +6
We present late-time Hubble Space Telescope (HST) ultraviolet (UV) and optical observations of the site of SN 2011dh in the galaxy M51, ~1164 days post-explosion. At the SN locatio…
