The Type II-P Supernova 2019mhm and Constraints on Its Progenitor System
J. Vazquez, C. D. Kilpatrick, G. Dimitriadis +4
We present pre- and post-explosion observations of the Type II-P supernova (SN~II-P) 2019mhm located in NGC~6753. Based on optical spectroscopy and photometry, we show that SN\,201…
Panchromatic evolution of three luminous red novae: Forbidden hugs in pandemic times -- IV
A. Pastorello, G. Valerin, M. Fraser +77
We present photometric and spectroscopic data on three extragalactic luminous red novae (LRNe): AT2018bwo, AT2021afy, and AT2021blu. AT2018bwo was discovered in NGC45 (at 6.8 Mpc)…
Progenitor and Close-In Circumstellar Medium of Type II Supernova 2020fqv from High-Cadence Photometry and Ultra-Rapid UV Spectroscopy
Samaporn Tinyanont, Ryan Ridden-Harper, Ryan Foley +35
We present observations of SN 2020fqv, a Virgo-cluster Type II core-collapse supernova (CCSN) with a high temporal resolution light curve from the Transiting Exoplanet Survey Satel…
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}…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
Wolf 1465: Not a Bright Dwarf Carbon Star
Bruce Margon, Georgios Dimitriadis
Wolf 1465 has been suggested as a candidate for a bright dwarf carbon star. It is not.
