Superflares on Solar Type Stars Observed with Kepler I. Statistical Properties of Superflares
Takuya Shibayama, Hiroyuki Maehara, Shota Notsu +6
By extending our previous study by Maehara et al. (2012), we searched for superflares on G-type dwarfs (solar type stars) using Kepler data for a longer period (500 days) than that…
High Dispersion Spectroscopy of the Superflare Star KIC6934317
Shota Notsu, Satoshi Honda, Yuta Notsu +5
We conducted the high-resolution spectroscopic observation with Subaru/HDS for a G-type star (KIC6934317). We selected this star from the data of the Kepler spacecraft. This star p…
Superflares on Solar-Type Stars Observed with Kepler II. Photometric Variability of Superflare-Generating Stars : A Signature of Stellar Rotation and Starspots
Yuta Notsu, Takuya Shibayama, Hiroyuki Maehara +6
We performed simple spot-model calculations for quasi-periodic brightness variations of solar-type stars showing superflares, by using Kepler photometric data. Most of superflare s…
