No Stripped Companion Material in the Nebular Spectrum of the "Two-Component" Type Ia Supernova ASASSN-18bt
M. A. Tucker, B. J. Shappee, J. P. Wisniewski
We analyze a KeckI/LRIS nebular spectrum taken 268 days after -band maximum of ASASSN-18bt (SN~2018oh), a Type Ia supernova (SN Ia) observed by {\it K2} at the time of explosion…
The first 48: Discovery and progenitor constraints on the Type Ia supernova 2013gy
S. Holmbo, M. D. Stritzinger, B. J. Shappee +26
We present an early-phase -band light curve and visual-wavelength spectra of the normal Type Ia supernova (SN) 2013gy. The light curve is constructed by determining the appropri…
Red vs Blue: Early observations of thermonuclear supernovae reveal two distinct populations?
Maximilian D. Stritzinger, Benjamin J. Shappee, Anthony L. Piro +10
We examine the early phase intrinsic color evolution of a dozen Type~Ia supernovae discovered within three days of the inferred time of first light () and ha…
ASASSN-18ey: The Rise of a New Black-Hole X-ray Binary
M. A. Tucker, B. J. Shappee, T. W. -S. Holoien +21
We present the discovery of ASASSN-18ey (MAXI J1820+070), a new black hole low-mass X-ray binary discovered by the All-Sky Automated Survey for SuperNovae (ASAS-SN). A week after A…
PS18kh: A New Tidal Disruption Event with a Non-Axisymmetric Accretion Disk
T. W. -S. Holoien, M. E. Huber, B. J. Shappee +38
We present the discovery of PS18kh, a tidal disruption event (TDE) discovered at the center of SDSS J075654.53+341543.6 ( Mpc) by the Pan-STARRS Survey for Transients.…
Interstellar Interlopers: Number Density and Origins of 'Oumuamua-like Objects
Aaron Do, Michael A. Tucker, John Tonry
We provide a calculation of Pan-STARRS' ability to detect objects similar to the interstellar object 1I/2017 U1 (hereafter 'Oumuamua), including the most detectable approach vector…
