Fast optical flares from M dwarfs detected by a one-second-cadence survey with Tomo-e Gozen
Masataka Aizawa, Kojiro Kawana, Kazumi Kashiyama +18
We report a one-second-cadence wide-field survey for M-dwarf flares using the Tomo-e Gozen camera mounted on the Kiso Schmidt telescope. We detect 22 flares from M3-M5 dwarfs with…
ASASSN-18aan: An Eclipsing SU UMa-type Cataclysmic Variable with a 3.6-hour Orbital Period and a Late G-type Secondary Star
Yasuyuki Wakamatsu, John R. Thorstensen, Naoto Kojiguchi +41
We report photometric and spectroscopic observations of the eclipsing SU UMa-type dwarf nova ASASSN-18aan. We observed the 2018 superoutburst with 2.3 mag brightening and found the…
Long-Term Near-Infrared Brightening of Non-Variable OH/IR Stars
Takafumi Kamizuka, Yoshikazu Nakada, Kenshi Yanagisawa +8
Non-variable OH/IR stars are thought to have just left the asymptotic giant branch (AGB) phase. In this conventional picture, they must still show strong circumstellar extinction c…
AKARI/IRC Near-Infrared Spectral Atlas of Galactic Planetary Nebulae
Ryou Ohsawa, Takashi Onaka, Itsuki Sakon +2
Near-infrared (2.5-5.0m) low-resolution () spectra of 72 Galactic planetary nebulae (PNe) were obtained with the Infrared Camera (IRC) in the post-helium phase.…
Unusual Carbonaceous Dust Distribution in PN G095.2+00.7
Ryou Ohsawa, Takashi Onaka, Itsuki Sakon +5
We investigate the polycyclic aromatic hydrocarbon features in the young Galactic planetary nebula PN G095.2+00.7 based on mid-infrared observations. The near- to mid-infrared spec…
A Search for Infrared Emission from Core-Collapse Supernovae at the Transitional Phase
Masaomi Tanaka, Takaya Nozawa, Itsuki Sakon +7
Most of the observational studies of supernova (SN) explosions are limited to early phases (< a few yr after the explosion) of extragalactic SNe and observations of SN remnants (>…
