Metallicities of Classical Cepheids in the Inner Galactic Disk
N. Matsunaga, D. Taniguchi, S. S. Elgueta +14
Metallicity gradients refer to the sloped radial profile of metallicities of gas and stars and are commonly seen in disk galaxies. A well-defined metallicity gradient of the Galact…
Oxygen, sulfur, and iron radial abundance gradients of classical Cepheids across the Galactic thin disk
R. da Silva, V. D'Orazi, M. Palla +25
Classical Cepheids (CCs) are solid distance indicators and tracers of young stellar populations. Our aim is to provide iron, oxygen, and sulfur abundances for the largest and most…
JASMINE: Near-Infrared Astrometry and Time Series Photometry Science
Daisuke Kawata, Hajime Kawahara, Naoteru Gouda +86
Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aero…
Effective temperatures of classical Cepheids from line-depth ratios in the H-band
V. Kovtyukh, B. Lemasle, N. Nardetto +6
The technique of line depth ratios (LDR) is one of the methods to determine the effective temperature of a star. They are crucial in the spectroscopic studies of variable stars lik…
Astrophysical calibration of the oscillator strengths of YJ-band absorption lines in classical Cepheids
S. S. Elgueta, N. Matsunaga, M. Jian +13
Newly-developed spectrographs with increased resolving powers, particularly those covering the near-IR range, allow the characterization of more and more absorption lines in stella…
Hunting for C-rich long-period variable stars in the Milky Way's bar-bulge using unsupervised classification of Gaia BP/RP spectra
Jason L. Sanders, Noriyuki Matsunaga
The separation of oxygen- and carbon-rich AGB sources is crucial for their accurate use as local and cosmological distance and age/metallicity indicators. We investigate the use of…
