[N I] 10400/10410 Å Lines as Possible Disk Wind Tracers in a Young Intermediate-Mass Star
Haruki Katoh, Chikako Yasui, Yuji Ikeda +10
In this study, we performed high-resolution near-infrared (NIR) spectroscopy (R = 28,000; -1.35 m) with a high signal-to-noise ratio on HD 200775, a very young (${\sim…
WARP: The Data Reduction Pipeline for the WINERED spectrograph
Satoshi Hamano, Yuji Ikeda, Shogo Otsubo +8
We present a data reduction pipeline written in Python for data obtained with the near-infrared cross-dispersed echelle spectrograph, WINERED, which yields a 0.911.35 m spect…
Survey of near-infrared diffuse interstellar bands in and bands. I. Newly identified bands
Satoshi Hamano, Naoto Kobayashi, Hideyo Kawakita +12
We searched for diffuse interstellar bands (DIBs) in the 0.911.33 m region by analyzing the near-infrared (NIR) high-resolution ( and 28,000) spectra of 31 redden…
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…
Identification of Absorption Lines of Heavy Metals in the Wavelength Range 0.97--1.32 Micron
Noriyuki Matsunaga, Daisuke Taniguchi, Mingjie Jian +13
Stellar absorption lines of heavy elements can give us various insights into the chemical evolution of the Galaxy and nearby galaxies. Recently developed spectrographs for the near…
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…
First detection of -- (0,0) bands of interstellar C and CN
Satoshi Hamano, Hideyo Kawakita, Naoto Kobayashi +12
We report the first detection of C -- (0,0) and CN -- (0,0) absorption bands in the interstellar medium. The detection was made using the near…
FeI lines in 0.91-1.33 m spectra of red giants for measuring the microturbulence and metallicities
Sohei Kondo, Kei Fukue, Noriyuki Matsunaga +16
For a detailed analysis of stellar chemical abundances, high-resolution spectra in the optical have mainly been used, while the development of near-infrared (NIR) spectrograph has…
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…
Correction of near-infrared high-resolution spectra for telluric absorption at 0.90-1.35 microns
Hiroaki Sameshima, Noriyuki Matsunaga, Naoto Kobayashi +15
We report a method of correcting a near-infrared (0.90-1.35 m) high-resolution () spectrum for telluric absorption using the corresponding spectrum of a telluric…
