A low-mass binary neutron star: long-term ejecta evolution and kilonovae with weak blue emission
Kyohei Kawaguchi, Sho Fujibayashi, Masaru Shibata +2
We study the long-term evolution of ejecta formed in a binary neutron star (BNS) merger that results in a long-lived remnant NS by performing a hydrodynamics simulation with the ou…
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…
Follow-up Observations for IceCube-170922A: Detection of Rapid Near-Infrared Variability and Intensive Monitoring of TXS 0506+056
Tomoki Morokuma, Yousuke Utsumi, Kouji Ohta +35
We present our follow-up observations to search for an electromagnetic counterpart of the IceCube high-energy neutrino, IceCube-170922A. Monitoring observations of a likely counter…
Photometric classification of HSC transients using machine learning
Ichiro Takahashi, Nao Suzuki, Naoki Yasuda +5
The advancement of technology has resulted in a rapid increase in supernova (SN) discoveries. The Subaru/Hyper Suprime-Cam (HSC) transient survey, conducted from fall 2016 through…
Simulations of early kilonova emission from neutron star mergers
Smaranika Banerjee, Masaomi Tanaka, Kyohei Kawaguchi +2
We present radiative transfer simulations for blue kilonovae hours after neutron star (NS) mergers by performing detailed opacity calculations for the first time. We calculate atom…
Relationship between Radar Cross Section and Optical Magnitude based on Radar and Optical Simultaneous Observations of Faint Meteors
Ryou Ohsawa, Akira Hirota, Kohei Morita +40
Radar and optical simultaneous observations of meteors are important to understand the size distribution of the interplanetary dust. However, faint meteors detected by high power l…
