Constraints on the rate of supernovae lasting for more than a year from Subaru/Hyper Suprime-Cam
Takashi J. Moriya, Ji-an Jiang, Naoki Yasuda +15
Some supernovae such as pair-instability supernovae are predicted to have the duration of more than a year in the observer frame. To constrain the rates of supernovae lasting for m…
Rapidly Evolving Transients from the Hyper Suprime-Cam SSP Transient Survey
Yusuke Tampo, Masaomi Tanaka, Keiichi Maeda +9
Rapidly evolving transients form a new class of transients which show shorter timescales of the light curves than those of typical core-collapse and thermonuclear supernovae. We pe…
Rapid Transients Originating from Thermonuclear Explosions in Helium White Dwarf Tidal Disruption Events
Kojiro Kawana, Keiichi Maeda, Naoki Yoshida +1
We study the emission properties of thermonuclear explosions in a helium white dwarf (WD) tidal disruption event (TDE). We consider a TDE where a 0.2 helium WD is disru…
HSC16aayt: Slowly evolving interacting transient rising for more than 100 days
Takashi J. Moriya, Masaomi Tanaka, Tomoki Morokuma +19
We report our observations of HSC16aayt (SN 2016jiu), which was discovered by the Subaru/Hyper Suprime-Cam (HSC) transient survey conducted as part of Subaru Strategic Program (SSP…
Second Data Release of the Hyper Suprime-Cam Subaru Strategic Program
Hiroaki Aihara, Yusra AlSayyad, Makoto Ando +62
This paper presents the second data release of the Hyper Suprime-Cam Subaru Strategic Program, a wide-field optical imaging survey on the 8.2 meter Subaru Telescope. The release in…
