Radiative-transfer models for dusty Type II supernovae
Luc Dessart, D. John Hillier, Arkaprabha Sarangi
Dust is expected to form on a year timescale in core-collapse supernova (SN) ejecta. Its existence is revealed through an infrared brightening, an optical dimming, or a blue-red em…
Carbon Monoxide Cooling in Radiative Transfer Modeling of Supernovae
Collin McLeod, D. John Hillier, Luc Dessart
Carbon monoxide (CO) emission has been observed in a number of core-collapse supernovae (SNe) and is known to be an important coolant at late times. We have implemented a chemical…
The evolution of continuum polarization in Type II supernovae as a diagnostic of ejecta morphology
Luc Dessart, D. John Hillier, Douglas C. Leonard
Linear polarization of the optical continuum of type II supernovae (SNe), together with its temporal evolution, is a promising source of information on the large-scale geometry of…
Oxygen abundance of gamma Vel from [O III] 88um Herschel/PACS spectroscopy
Paul A Crowther, M J Barlow, P Royer +4
We present Herschel PACS spectroscopy of the [O III] 88.4um fine-structure line in the nearby WC8+O binary system gamma Vel to determine its oxygen abundance. The critical density…
Solving the gamma-ray radiative transfer equation for supernovae
Kevin D. Wilk, D. John Hillier, Luc Dessart
We present a new relativistic radiative-transfer code for -rays of energy less than 5 MeV in supernova (SN) ejecta. This code computes the opacities, the prompt emissivity (i.e.…
Models of interacting supernovae and their spectral diversity
Luc Dessart, D. John Hillier, Edouard Audit +2
Using radiation-hydrodynamics and radiative-transfer simulations, we explore the origin of the spectral diversity of interacting supernovae (SNe) of type IIn. We revisit SN1994W an…
