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…
Lightcurve and spectral modelling of the Type IIb SN 2020acat. Evidence for a strong Ni bubble effect on the diffusion time
Mattias Ergon, Peter Lundqvist, Claes Fransson +10
We use the light curve and spectral synthesis code JEKYLL to calculate a set of macroscopically mixed Type IIb supernova (SN) models, which are compared to both previously publishe…
SN 2019odp: A Massive Oxygen-Rich Type Ib Supernova
T. Schweyer, J. Sollerman, A. Jerkstrand +18
We present and analyze observations of the Type Ib supernova (SN) 2019odp (a.k.a ZTF19abqwtfu) covering epochs within days of the explosion to the nebular phase at 360 d post-explo…
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…
SN 2020acat: A purr-fect example of a fast rising Type IIb Supernova
K. Medler, P. A. Mazzali, J. Teffs +31
The Ultra-Violet (UV) and Near Infrared (NIR) photometric and optical spectroscopic observations of SN 2020acat covering days after explosion are presented here. U…
