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…
The Immediate, Exemplary, and Fleeting echelle spectroscopy of SN 2023ixf: Monitoring acceleration of slow progenitor circumstellar material, driven by shock interaction
Danielle Dickinson, Dan Milisavljevic, Braden Garretson +12
We present high resolution WIYN/NEID echelle spectroscopy (R ,000) of the supernova (SN) 2023ixf in M101, obtained 1.51 to 18.51 days after explosion over nine epochs. D…
Spectropolarimetric modeling of interacting Type II supernovae. Application to early-time observations of SN1998S
Luc Dessart, Douglas C. Leonard, Sergiy S. Vasylyev +1
High-cadence surveys of the sky are revealing that a large fraction of red-supergiant (RSG) stars, which are progenitors of Type II-Plateau (II-P) supernovae (SNe), explode within…
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…
