Apache Point Observatory (APO)/SMARTS Flare Star Campaign Observations. I. Blue Wing Asymmetries in Chromospheric Lines during Mid-M-Dwarf Flares from Simultaneous Spectroscopic and Photometric Observation Data
Yuta Notsu   Adam F. Kowalski   Hiroyuki Maehara   Kosuke Namekata   Kenji Hamaguchi   Teruaki Enoto   Isaiah I. Tristan   Suzanne L. Hawley   James R. A. Davenport   Satoshi Honda   Kai Ikuta   Shun Inoue   Keiichi Namizaki   Daisaku Nogami   Kazunari Shibata   
The Astrophysical Journal   961(2) 189-189   2024年1月
Abstract

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 ...
 
A Superflare on YZ Canis Minoris Observed by the Seimei Telescope and TESS: Red Asymmetry of Hα Emission Associated with White-light Emission
Keiichi Namizaki   Kosuke Namekata   Hiroyuki Maehara   Yuta Notsu   Satoshi Honda   Daisaku Nogami   Kazunari Shibata   
The Astrophysical Journal   945(1) 61-61   2023年3月   [査読有り]
<jats:title>Abstract</jats:title>
<jats:p>Active M-type stars are known to often produce superflares on the surface. Radiation from stellar (super)flares is important for exoplanet habitability, but the mechanisms are not well understood. In this...
 
Four-hundred Very Metal-poor Stars Studied with LAMOST and Subaru. II. Elemental Abundances
Haining Li   Wako Aoki   Tadafumi Matsuno   Qianfan Xing   Takuma Suda   Nozomu Tominaga   Yuqin Chen   Satoshi Honda   Miho N. Ishigaki   Jianrong Shi   Jingkun Zhao   Gang Zhao   
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...

Spectroscopic Determination of Capella's Photospheric Abundances: Possible Influence of Stellar Activity
Yoichi Takeda   Osamu Hashimoto   Satoshi Honda   
   2018年6月   
Capella is a spectroscopic binary consisting of two G-type giants, where the
primary (G8III) is a normal red-clump giant while the secondary (G0III) is a
chromospherically-active fast rotator showing considerable overabundance of Li
as Li-enhanced...
 
Statistical Study of Solar White-light Flares and Comparison with Superflares on Solar-type Stars
Kosuke Namekata   Takahito Sakaue   Kyoko Watanabe   Ayumi Asai   Hiroyuki Maehara   Yuta Notsu   Shota Notsu   Satoshi Honda   Takako T. Ishii   Kai Ikuta   Daisaku Nogami   Kazunari Shibata   
   2018年4月   
Recently, many superflares on solar-type stars were discovered as white-light
flares (WLFs). A correlation between the energies (E) and durations (t) of
superflares is derived as Tex, and this can be theoretically
explained by magn...
 
Time resolved spectroscopic observations of an M-dwarf flare star EV Lacertae during a flare
Satoshi Honda   Yuta Notsu   Kosuke Namekata   Shota Notsu   Hiroyuki Maehara   Kai Ikuta   Daisaku Nogami   Kazunari Shibata   
   2018年4月   
We have performed 5 night spectroscopic observation of the Halpha line of EV
Lac with a medium wavelength resolution (R~ 10,000) using the 2m Nayuta
telescope at the Nishi-Harima Astronomical Observatory. EV Lac always possesses
the Halpha emissio...
 
Subaru Hyper Suprime-Cam Survey for an optical counterpart of GW170817
Nozomu Tominaga   Masaomi Tanaka   Tomoki Morokuma   Yousuke Utsumi   Masaki S Yamaguchi   Naoki Yasuda   Masayuki Tanaka   Michitoshi Yoshida   Takuya Fujiyoshi   Hisanori Furusawa   Koji S Kawabata   Chien-Hsiu Lee   Kentaro Motohara   Ryou Ohsawa   Kouji Ohta   Tsuyoshi Terai   Fumio Abe   Wako Aoki   Yuichiro Asakura   Sudhanshu Barway   Ian A Bond   Kenta Fujisawa   Satoshi Honda   Kunihito Ioka   Youichi Itoh   Nobuyuki Kawai   Ji Hoon Kim   Naoki Koshimoto   Kazuya Matsubayashi   Shota Miyazaki   Tomoki Saito   Yuichiro Sekiguchi   Takahiro Sumi   Paul J Tristram   J-Gem Collaboration   
Publications of the Astronomical Society of Japan   70(2) 1-11   2018年3月   
We perform a z-band survey for an optical counterpart of the binary neutron star coalescence GW170817 with Subaru/Hyper Suprime-Cam. Our untargeted transient search covers 23.6 deg2 corresponding to the 56.6% credible region of GW170817 and reache...
 
The Spectroscopic Variations of the FU Orionis Object V960 Mon
Yuhei Takagi   Satoshi Honda   Akira Arai   Kumiko Morihana   Jun Takahashi   Yumiko Oasa   Yoichi Itoh   
Astronomical Journal   155(2)    2018年2月   
We present the results of the spectroscopic monitoring of the FU Orionis type star V960 Mon. Spectroscopic variations of an FU Orionis type star will provide valuable information of its physical nature and the mechanism of the outburst. We conduct...
