A hot and fast ultra-stripped supernova that likely formed a compact neutron star binary
K. De, M. M. Kasliwal, E. O. Ofek +24
Compact neutron star binary systems are produced from binary massive stars through stellar evolution involving up to two supernova explosions. The final stages in the formation of…
The Broad Absorption Line Tidal Disruption Event iPTF15af: Optical and Ultraviolet Evolution
N. Blagorodnova, S. B. Cenko, S. R. Kulkarni +16
We present multi-wavelength observations of the tidal disruption event (TDE) iPTF15af, discovered by the intermediate Palomar Transient Factory (iPTF) survey at redshift $z=0.07897…
Oxygen and helium in stripped-envelope supernovae
C. Fremling, J. Sollerman, M. M. Kasliwal +23
We present an analysis of 507 spectra of 173 stripped-envelope (SE) supernovae (SNe) discovered by the untargeted Palomar Transient Factory (PTF) and intermediate PTF (iPTF) survey…
Type Ibn Supernovae Show Photometric Homogeneity and Spectral Diversity at Maximum Light
Griffin Hosseinzadeh, Iair Arcavi, Stefano Valenti +34
Type Ibn supernovae (SNe) are a small yet intriguing class of explosions whose spectra are characterized by low-velocity helium emission lines with little to no evidence for hydrog…
PTF 13efv - An outburst 500 days prior to the SNHunt 275 explosion and its radiative efficiency
E. O. Ofek, S. B. Cenko, N. J. Shaviv +15
The progenitors of some supernovae (SNe) exhibit outbursts with super-Eddington luminosities prior to their final explosions. This behavior is common among Type IIn SNe, but the dr…
Long-rising Type II supernovae from PTF and CCCP
F. Taddia, J. Sollerman, C. Fremling +17
Supernova (SN) 1987A was a peculiar H-rich event with a long-rising (LR) light curve (LC), stemming from a compact blue supergiant star (BSG). Only a few similar events have been p…
