Time-series photometry of Earth flyby asteroid 2012 DA14
Tsuyoshi Terai, Seitaro Urakawa, Jun Takahashi +7
Context. The object 2012 DA14 is a near-Earth asteroid with a size of several tens of meters. It had approached closely the Earth on 15 February, 2013 UT, providing an opportunity…
NMR study of the Superconducting gap variation near the Mott transition in CsC
P. Wzietek, T. Mito, H. Alloul +3
Former extensive studies of superconductivity in the \textit{A}C compounds, where \textit{A} is an alkali, have led to consider that Bardeen Cooper Schrieffer (BCS) el…
High Ecliptic Latitude Survey for Small Main-Belt Asteroids
Tsuyoshi Terai, Jun Takahashi, Yoichi Itoh
Main-belt asteroids have been continuously colliding with one another since they were formed. Its size distribution is primarily determined by the size dependence of asteroid stren…
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…
