Fast optical flares from M dwarfs detected by a one-second-cadence survey with Tomo-e Gozen
Masataka Aizawa, Kojiro Kawana, Kazumi Kashiyama +18
We report a one-second-cadence wide-field survey for M-dwarf flares using the Tomo-e Gozen camera mounted on the Kiso Schmidt telescope. We detect 22 flares from M3-M5 dwarfs with…
Four New Self-lensing Binaries from Kepler: Radial Velocity Characterization and Astrophysical Implications
Kento Masuda, Hajime Kawahara, David W. Latham +5
In Kawahara et al. (2018) and Masuda et al. (2019), we reported the discovery of four self-lensing binaries consisting of F/G-type stars and (most likely) white dwarfs whose masses…
Self-lensing Discovery of a White Dwarf in an Unusually Wide Orbit Around a Sun-like Star
Kento Masuda, Hajime Kawahara, David W. Latham +4
We report the discovery of the fifth self-lensing binary in which a low-mass white dwarf (WD) gravitationally magnifies its 15th magnitude G-star companion, KIC 8145411, during ecl…
Discovery of three self-lensing binaries from Kepler
Hajime Kawahara, Kento Masuda, Morgan MacLeod +3
We report the discovery of three edge-on binaries with white dwarf companions that gravitationally magnify (instead of eclipsing) the light of their stellar primaries, as revealed…
Absolute Dimensions of a Flat Hierarchical Triple System KIC 6543674 from the Kepler Photometry
Kento Masuda, Sho Uehara, Hajime Kawahara
Many of the Kepler close binaries are suggested to constitute hierarchical triple systems through their eclipse timing variations (ETVs). Eclipses by the third body in those system…
