New assignments of the CaH transitions in the sunspot umbral spectrum and effective temperature estimation using molecular lines
Kosei Usami, Kaori Kobayashi, Hiroyuki Maehara
High-resolution spectroscopy observations of sunspots offer a unique natural laboratory for detailed molecular spectroscopy. Calcium monohydride (CaH) is a vital spectroscopic trac…
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…
Time evolution of white-light flare accompanied by probable postflare loops on M-type dwarf EV Lacertae
Shinnosuke Ichihara, Daisaku Nogami, Kosuke Namekata +6
White-light flares are explosive phenomena accompanied by brightening of continuum from near-ultraviolet to optical, which occur on the Sun and stars. In order to investigate the m…
Optical Observations of the High Mass X-ray Binary MAXI J0709159/LY CMa
Megumi Shidatsu, Nobuyuki Kawai, Hiroyuki Maehara +12
We report on the optical spectroscopic monitoring of the X-ray transient MAXI J0709159 (identified as the Be star LY CMa) performed for about 1.5 months after the X-ray detectio…
