Statistical Properties of Superflares on Solar-type Stars: Results Using All of the Kepler Primary Mission Data
Soshi Okamoto, Yuta Notsu, Hiroyuki Maehara +5
We report the latest statistical analyses of superflares on solar-type (G-type main-sequence; effective temperature is 5100 - 6000 K) stars using all of the primary missio…
Time-resolved spectroscopy and photometry of an M dwarf flare star YZ Canis Minoris with OISTER and TESS: Blue asymmetry in H line during the non-white light flare
Hiroyuki Maehara, Yuta Notsu, Kousuke Namekata +15
In this paper, we present the results from spectroscopic and photometric observations of the M-type flare star YZ CMi in the framework of the Optical and Infrared Synergetic Telesc…
Starspot mapping with adaptive parallel tempering I: Implementation of computational code
Kai Ikuta, Hiroyuki Maehara, Yuta Notsu +7
Starspots are thought to be regions of locally strong magnetic fields, similar to sunspots, and they can generate photometric brightness modulations. To deduce stellar and spot pro…
Temporal Evolution of Spatially-Resolved Individual Star Spots on a Planet-Hosting Solar-type Star: Kepler 17
Kosuke Namekata, James R. A. Davenport, Brett M. Morris +9
Star spot evolution is visible evidence of the emergence/decay of the magnetic field on stellar surface, and it is therefore important for the understanding of the underlying stell…
