High-Precision Near-Infrared Abundances of Solar Analogs in the YJ Bands
Noriyuki Matsunaga, Takuji Tsujimoto, Daisuke Taniguchi +12
We present a near-infrared abundance analysis of 46 solar analogs with known ages, observed with the WINERED WIDE-mode spectrograph at a resolution of . Using an empi…
Discovery of WINERED-HVS1: A metal-rich hyper-velocity star candidate ejected from the Galactic center
Kohei Hattori, Daisuke Taniguchi, Takuji Tsujimoto +4
We report the discovery of a metal-rich red giant star, WINERED-HVS1, which is a candidate for a hyper-velocity star (HVS). Its past trajectory suggests that this star may have bee…
Line-depth ratios as indicators of effective temperature and surface gravity
Noriyuki Matsunaga, Mingjie Jian, Daisuke Taniguchi +1
The analysis of stellar spectra depends upon the effective temperature (Teff) and the surface gravity (log g). However, the estimation of log g with high accuracy is challenging. A…
