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…
Do Kepler superflare stars really include slowly-rotating Sun-like stars ? - Results using APO 3.5m telescope spectroscopic observations and Gaia-DR2 data -
Yuta Notsu, Hiroyuki Maehara, Satoshi Honda +7
We report the latest view of Kepler solar-type (G-type main-sequence) superflare stars, including recent updates with Apache Point Observatory (APO) 3.5m telescope spectroscopic ob…
Lifetimes and Emergence/Decay Rates of Star Spots on Solar-type Stars Estimated by Kepler Data in Comparison with Those of Sunspots
Kosuke Namekata, Hiroyuki Maehara, Yuta Notsu +7
Active solar-type stars show large quasi-periodic brightness variations caused by stellar rotations with star spots, and the amplitude changes as the spots emerge and decay. The Ke…
Statistical Studies of Solar White-Light Flares and Comparisons with Superflares on Solar-type Stars
Kosuke Namekata, Takahito Sakaue, Kyoko Watanabe +9
Recently, many superflares on solar-type stars have been discovered as white-light flares (WLFs). The statistical study found a correlation between their energies () and duratio…
