Type II-P Supernova Progenitor Star Initial Masses and SN 2020jfo: Direct Detection, Light Curve Properties, Nebular Spectroscopy, and Local Environment
Charles D. Kilpatrick, Luca Izzo, Rory O. Bentley +23
We present optical, ultraviolet, and infrared data of the type II supernova (SN II) 2020jfo at 14.5 Mpc. This wealth of multiwavelength data allows to compare different metrics com…
SN2023ixf in Messier 101: A Variable Red Supergiant as the Progenitor Candidate to a Type II Supernova
Charles D. Kilpatrick, Ryan J. Foley, Wynn V. Jacobson-Galán +15
We present pre-explosion optical and infrared (IR) imaging at the site of the type II supernova (SN II) 2023ixf in Messier 101 at 6.9 Mpc. We astrometrically registered a ground-ba…
The Early Phases of Supernova 2020pni: Shock-Ionization of the Nitrogen-Enriched Circumstellar Material
G. Terreran, W. V. Jacobson-Galan, J. H. Groh +20
We present multiwavelength observations of the Type II SN 2020pni. Classified at days after explosion, the object showed narrow (FWHM $<250\,\textrm{km}\,\textrm{s}^{-1}…
Carnegie Supernova Project-II: The Near-infrared Spectroscopy Program
E. Y. Hsiao, M. M. Phillips, G. H. Marion +42
Shifting the focus of Type Ia supernova (SN Ia) cosmology to the near-infrared (NIR) is a promising way to significantly reduce the systematic errors, as the strategy minimizes our…
Early gray dust formation in the type IIn SN 2005ip
Ann-Sofie Bak Nielsen, Jens Hjorth, Christa Gall
The physical characteristics of dust formed in supernovae is poorly known. In this paper, we investigate the extinction properties of dust formed in the type IIn SN 2005ip. The obs…
SN 2017dio: a type-Ic supernova exploding in a hydrogen-rich circumstellar medium
Hanindyo Kuncarayakti, Keiichi Maeda, Christopher J. Ashall +42
SN 2017dio shows both spectral characteristics of a type-Ic supernova (SN) and signs of a hydrogen-rich circumstellar medium (CSM). Prominent, narrow emission lines of H and He are…
