Observation of the first gravitational microlensing event in a sparse stellar field : the Tago event
A. Fukui, F. Abe, K. Ayani +17
We report the observation of the first gravitational microlensing event in a sparse stellar field, involving the brightest (V=11.4 mag) andclosest (~ 1 kpc) source star to date. Th…
The Earliest Optical Observations of GRB 030329
K. Torii, T. Kato, H. Yamaoka +9
We present the earliest optical imaging observations of GRB 030329 related to SN 2003dh. The burst was detected by the HETE-2 satellite at 2003 March 29, 11:37:14.67 UT. Our wide-f…
Early-Phase Spectra of "Hypernova" SN 2002ap
K. Kinugasa, H. Kawakita, K. Ayani +6
The spectral evolution of the peculiar SN Ic 2002ap during the first 40 days is presented. The spectra display very broad absorption features, which are typical of "hypernovae". Th…
The Type Ic Hypernova SN 2002ap
P. A. Mazzali, J. Deng, K. Maeda +31
Photometric and spectroscopic data of the energetic Type Ic supernova (SN) 2002ap are presented, and the properties of the SN are investigated through models of its spectral evolut…
Discovery of a Dwarf Nova Breaking the Standard Sequence of Compact Binary Evolution
M. Uemura, T. Kato, R. Ishioka +1
We revealed that the dwarf nova 1RXS J232953.9+062814 is an SU UMa-type system with a superhump period of 66.774+/-0.010 min. The short period strongly indicates that the orbital p…
