We conducted the time-resolved simultaneous optical spectroscopic and photometric observations of mid-M-dwarf flare stars YZ CMi, EV Lac, and AD Leo. Spectroscopic observations were obtained using Apache Point Observatory 3.5 m and Smal...
 
Starspot Mapping with Adaptive Parallel Tempering. II. Application to TESS Data for M-dwarf Flare Stars AU Microscopii, YZ Canis Minoris, and EV Lacertae
Kai Ikuta   Kosuke Namekata   Yuta Notsu   Hiroyuki Maehara   Soshi Okamoto   Satoshi Honda   Daisaku Nogami   Kazunari Shibata   
The Astrophysical Journal   948(1) 64-64   2023年5月   [査読有り]
Abstract

Starspots and stellar flares are indicators of stellar magnetic activity. The magnetic energy stored around spots is thought to be the origin of flares, but the connection is not completely understood. To investigate the relation betwee...
 
Detection of a High-velocity Prominence Eruption Leading to a CME Associated with a Superflare on the RS CVn-type Star V1355 Orionis
Shun Inoue   Hiroyuki Maehara   Yuta Notsu   Kosuke Namekata   Satoshi Honda   Keiichi Namizaki   Daisaku Nogami   Kazunari Shibata   
The Astrophysical Journal   948(1) 9-9   2023年4月   [査読有り]
Abstract

Stellar coronal mass ejections (CMEs) have recently received much attention for their impacts on exoplanets and stellar evolution. Detecting prominence eruptions, the initial phase of CMEs, as the blueshifted excess component of Balmer ...

The Astrophysical Journal   931(2) 147-147   2022年6月   [査読有り]
Abstract

We present homogeneous abundance analysis of over 20 elements for 385 very metal-poor (VMP) stars based on the LAMOST survey and follow-up observations with the Subaru Telescope. It is the largest high-resolution VMP sample (including 3...

Vaubaillon   Jun-Ichi Watanabe   
Astronomical Journal   152(6)    2016年12月   
Multiple outbursts of a Jupiter-family comet (JFC), 15P/Finlay, occurred from late 2014 to early 2015. We conducted an observation of the comet after the first outburst and subsequently witnessed another outburst on 2015 January 15.6-15.7. The gas...

We present extensively dense observations of the super-Chandrasekhar supernova (SC SN) candidate SN 2012dn from -11 to +140 d after the date of its B-band maximum in the optical and near-infrared (NIR) wavelengths conducted through the OISTER ToO ...
 
Statistical properties of superflares on solar-type stars with Kepler data

   2016年7月   
Superflares are flares that release total energy 10Tex10Tex times
greater than that of the biggest solar flares with energy of Tex10Tex
erg. We searched superflares on solar-type stars (G-type main sequence stars)
using the Kepler 30-...
 
MONITORING OBSERVATIONS OF THE JUPITER-FAMILY COMET 17P/HOLMES DURING ITS 2014 PERIHELION PASSAGE
Yuna Grace Kwon   Masateru Ishiguro   Hidekazu Hanayama   Daisuke Kuroda   Satoshi Honda   Jun Takahashi   Yoonyoung Kim   Myung Gyoon Lee   Young-Jun Choi   Myung-Jin Kim   Jeremie J.

Astrophysical Journal   818(1)    2016年2月   
We performed a monitoring observation of a Jupiter-family comet, 17P/Holmes, during its 2014 perihelion passage to investigate its secular change in activity. The comet has drawn the attention of astronomers since its historic outburst in 2007, an...
 
Statistical properties of superflares on solar-type stars based on the Kepler 1-min cadence data
Hiroyuki Maehara   Takuya Shibayama   Yuta Notsu   Shota Notsu   Satoshi Honda   Daisaku Nogami   Kazunari Shibata   
   2016年1月   
We searched for superflares on solar-type stars using the Kepler
short-cadence (1-min sampling) data in order to detect superflares with short
duration. We found 187 superflares on 23 solar-type stars whose bolometric
energy ranges from the order ...
