Effective temperatures of red supergiants estimated from line-depth ratios of iron lines in the YJ bands, 0.97--1.32 micron
Daisuke Taniguchi, Noriyuki Matsunaga, Mingjie Jian +10
Determining the effective temperatures (Teff) of red supergiants (RSGs) observationally is important in many fields of stellar physics and galactic astronomy, yet some significant…
Understanding the velocity distribution of the Galactic Bulge with APOGEE and Gaia
Yingying Zhou, Zhao-Yu Li, Iulia Simion +5
We revisit the stellar velocity distribution in the Galactic bulge/bar region with APOGEE DR16 and {\it Gaia} DR2, focusing in particular on the possible high-velocity (HV) peaks a…
Red Supergiants in M31 and M33 I. The Complete Sample
Yi Ren, Biwei Jiang, Ming Yang +3
The aim of this paper is to establish a complete sample of red supergiants (RSGs) in M31 and M33. The member stars of the two galaxies are selected from the near-infrared (NIR) poi…
The effect of surface gravity on line-depth ratios in the wavelength range 0.97-1.32 μm
Mingjie Jian, Daisuke Taniguchi, Noriyuki Matsunaga +10
A line-depth ratio (LDR) of two spectral lines with different excitation potentials is expected to be correlated with the effective temperature (). It is possible t…
Intrinsic Color Indices of Early-Type Dwarf Stars
Dingshan Deng, Yang Sun, Mingjie Jian +2
Early-type stars are short lived and scarce in comparison with other types. Based on the recently released catalogs of early type stars from the largest LAMOST spectroscopic survey…
