Radial-velocity search and statistical studies for short-period planets in the Pleiades open cluster
Takuya Takarada, Bun'ei Sato, Masashi Omiya +2
We report radial-velocity search for short-period planets in the Pleiades open cluster. We observed 30 Pleiades member stars at the Okayama Astrophysical Observatory (OAO) with Hig…
Dippers from the TESS Full-Frame Images I: The Results of the first 1 year data and Discovery of A Runaway dipper
Tomoyuki Tajiri, Hajime Kawahara, Masataka Aizawa +9
We present a comprehensive catalog of the dippers---young stellar objects that exhibit episodic dimming---derived from the one year's worth of data of Transiting Exoplanet Survey S…
SIRIUS project. I. Star formation models for star-by-star simulations of star clusters and galaxy formation
Yutaka Hirai, Michiko S. Fujii, Takayuki R. Saitoh
Most stars are formed as star clusters in galaxies, which then disperse into galactic disks. Upcoming exascale supercomputational facilities will enable performing simulations of g…
Gaia's Detectability of Black Hole-Main Sequence Star Binaries Formed in Open Clusters
Minori Shikauchi, Jun Kumamoto, Ataru Tanikawa +1
Black hole-main sequence star (BH-MS) binaries are one of the targets of the future data releases of the astrometric satellite {\it Gaia}. They are supposed to be formed in two mai…
Merger rate density of binary black holes formed in open clusters
Jun Kumamoto, Michiko S. Fujii, Ataru Tanikawa
Several binary black holes (BBHs) have been observed using gravitational wave detectors. For the formation mechanism of BBHs, two main mechanisms, isolated binary evolution and dyn…
