Method to Estimate the Effective Temperatures of Late-Type Giants using Line-Depth Ratios in the Wavelength Range 0.97-1.32m
Daisuke Taniguchi, Noriyuki Matsunaga, Naoto Kobayashi +7
The effective temperature, one of the most fundamental atmospheric parameters of a star, can be estimated using various methods, and here we focus on the method using line-depth ra…
Detailed chemical composition of classical Cepheids in the LMC cluster NGC 1866 and in the field of the SMC
B. Lemasle, M. A. T. Groenewegen, E. K. Grebel +11
Context: Cepheids are excellent tracers of young stellar populations. They play a crucial role in astrophysics as standard candles. The chemistry of classical Cepheids in the Milky…
Mira Variable Stars From LAMOST DR4 Data: Emission Features, Temperature Types, and Candidate Selection
Yuhan Yao, Chao Liu, Licai Deng +2
Based on an extensive spectral study of a photometrically confirmed sample of Mira variables, we find a relationship between relative Balmer emission-line strength and spectral tem…
Variable stars in the northern Galactic plane from KISOGP
Noriyuki Matsunaga
We have conducted a large-scale survey of the northern plane using Kiso Wide Field Camera attached to Schmidt telescope at Kiso observatory. The KISOGP (KWFC Intensive Survey of th…
Discovery of carbon-rich Miras in the Galactic bulge
Noriyuki Matsunaga, John W. Menzies, Michael W. Feast +4
Only one carbon-rich (C-rich, hereinafter) Mira variable has so far been suggested as a member of the Galactic bulge and this is in a symbiotic system. Here we describe a method fo…
New classical Cepheids in the inner part of the northern Galactic disk and their kinematics
Satoshi Tanioka, Noriyuki Matsunaga, Kei Fukue +3
The characteristics of the inner Galaxy remain obscured by significant dust extinction, and hence infrared surveys are useful to find young Cepheids whose distances and ages can be…
