Absorption Lines in the 0.91-1.33 m Spectra of Red Giants for Measuring Abundances of Mg, Si, Ca, Ti, Cr, and Ni
K. Fukue, N. Matsunaga, S. Kondo +13
Red giants show a large number of absorption lines in both optical and near-infrared wavelengths. Still, the characteristics of the lines in different wave passbands are not necess…
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…
Possible progression of mass flow processes around young intermediate-mass stars based on high-resolution near-infrared spectroscopy. I. Taurus
Chikako Yasui, Satoshi Hamano, Kei Fukue +12
We used the WINERED spectrograph to perform near-infrared high-resolution spectroscopy (resolving power ,000) of 13 young intermediate-mass stars in the Taurus star-forming…
WINERED high-resolution near-infrared line catalog: A-type star
H. Sameshima, Y. Ikeda, N. Matsunaga +13
We present a catalog of absorption lines in the z', Y, and J bands that we identified in 21 Lyn, a slowly rotating A0.5 V star. We detected 155 absorption features in the high-reso…
A newly-identified emission-line region around P Cygni
Misaki Mizumoto, Naoto Kobayashi, Satoshi Hamano +12
We present a high-resolution () near-infrared (9,100-13,500 ) long-slit spectrum of P Cygni obtained with the newly commissioned WINERED spectrograph in Japan.…
On the chemical abundances of Miras in clusters: V1 in the metal-rich globular NGC 5927
V. D'Orazi, D. Magurno, G. Bono +50
We present the first spectroscopic abundance determination of iron, alpha-elements (Si, Ca and Ti) and sodium for the Mira variable V1 in the metal-rich globular cluster NGC 5927.…
