Discovery of a compact hierarchical triple main-sequence star system while searching for binary stars with compact objects
Ataru Tanikawa, Akito Tajitsu, Satoshi Honda +5
We have discovered a compact hierarchical triple main-sequence star system, which is cataloged as Gaia DR3 1010268155897156864 or TIC 21502513. Hereafter, we call it ``G1010''. G10…
Two unseen massive white dwarf candidates in close binaries
Yuta Shiraishi, Kenta Hotokezaka, Kento Masuda +10
We report the discovery of two binary systems, each consisting of a slightly bloated G-type main-sequence star and an unseen companion, identified through photometric data from TES…
GW231123 Formation from Population III Stars: Isolated Binary Evolution
Ataru Tanikawa, Shuai Liu, WeiWei Wu +2
GW231123 is a merger of two black holes (BHs) with estimated masses exceeding , making them the most massive BHs discovered to date via gravitational wave (GW…
Double Compact Binary Merger Rate Density in Open Star Clusters: Black Holes, Neutron Stars, and White Dwarfs
Savannah Cary, Michiko Fujii, Long Wang +1
Studying compact-object binary mergers in star clusters is crucial for understanding stellar evolution and dynamical interactions in galaxies. Open clusters in particular are more…
Unevolved Li-rich stars at low metallicity: a possible formation pathway through novae
Tadafumi Matsuno, Alex Kemp, Ataru Tanikawa +7
A small fraction of low-mass stars have been found to have anomalously high Li abundances. Although it has been suggested that mixing during the red giant branch phase can lead to…
Compact Binary Formation in Open Star Clusters II: Difficulty of Gaia NS formation in low-mass star clusters
Ataru Tanikawa, Long Wang, Michiko S. Fujii
Gaia mission offers opportunities to search for compact binaries not involved in binary interactions (hereafter inert compact binaries), and results in the discoveries of binaries…
