Journal ArticleDOI
No signature of ejecta interaction with a stellar companion in three type Ia supernovae
Rob P. Olling,Richard F. Mushotzky,Edward J. Shaya,Armin Rest,Peter M. Garnavich,Brad E. Tucker,Brad E. Tucker,Daniel Kasen,Daniel Kasen,S. Margheim,Alexei V. Filippenko +10 more
TL;DR: No signatures of the supernova ejecta interacting with nearby companions are found, consistent with the idea that these three supernovae resulted from the merger of binary white dwarfs or other compact stars such as helium stars.
Journal ArticleDOI
A fast-evolving luminous transient discovered by K2/Kepler
Armin Rest,Peter M. Garnavich,David K. Khatami,David K. Khatami,Daniel Kasen,Daniel Kasen,Brad E. Tucker,Brad E. Tucker,Edward J. Shaya,Rob P. Olling,Richard F. Mushotzky,A. Zenteno,S. Margheim,G. Strampelli,David James,Robert Connon Smith,F. Forster,V. A. Villar +17 more
TL;DR: In this paper, the authors present the most extreme example of this class of objects, KSN 2015K, with a rise time of only 2.2 days and a time above half-maximum of only 6.8 days.
