SN 2023zaw: an ultra-stripped, nickel-poor supernova from a low-mass progenitor
Kaustav K. Das, Christoffer Fremling, Mansi M. Kasliwal +34
We present SN 2023zaw a sub-luminous ( mag) and rapidly-evolving supernova ( days), with the lowest nickel mass (…
Helium giant stars as progenitors of rapidly fading Type Ibc supernovae
Io Kleiser, Jim Fuller, Daniel Kasen
Type I rapidly fading supernovae (RFSNe) appear to originate from hydrogen-free stars with large radii that produce predominantly shock-cooling light curves, in contrast with more…
Spectra of Hydrogen-Poor Superluminous Supernovae from the Palomar Transient Factory
Robert M. Quimby, Annalisa De Cia, Avishay Gal-Yam +20
Most Type I superluminous supernovae (SLSNe-I) reported to date have been identified by their high peak luminosities and spectra lacking obvious signs of hydrogen. We demonstrate t…
Models of bright nickel-free supernovae from stripped massive stars with circumstellar shells
Io Kleiser, Daniel Kasen, Paul Duffell
The nature of an emerging class of rapidly fading supernovae (RFSNe)--characterized by their short-lived light curve duration, but varying widely in peak brightness--remains puzzli…
SN 2015U: A Rapidly Evolving and Luminous Type Ibn Supernova
Isaac Shivvers, WeiKang Zheng, Jon Mauerhan +7
Supernova (SN) 2015U (also known as PSN J07285387+3349106) was discovered in NGC 2388 on 2015 Feb. 11. A rapidly evolving and luminous event, it showed effectively hydrogen-free sp…
Rapidly Fading Supernovae from Massive Star Explosions
Io Kleiser, Daniel Kasen
Transient surveys have recently discovered a class of supernovae (SNe) with extremely rapidly declining light curves. These events are also often relatively faint, especially compa…
GRB 090902B: afterglow observations and implications
S. B. Pandey, C. A. Swenson, D. A. Perley +30
The optical-infrared afterglow of the LAT-detected long duration burst, GRB 090902B, has been observed by several instruments. The earliest detection by ROTSE-IIIa occurred 80 minu…
