[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…
A High-Resolution Non-Detection of Escaping Helium In The Ultra-Hot Neptune LTT 9779b: Evidence for Weakened Evaporation
Shreyas Vissapragada, Patrick McCreery, Leonardo A. Dos Santos +16
The recent discovery of ``ultra-hot'' ( day) Neptunes has come as a surprise: some of these planets have managed to retain gaseous envelopes despite being close enough to th…
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…
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…
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…
A Warm Near-Infrared High-Resolution Spectrograph with Very High Throughput (WINERED)
Sohei Kondo, Yuji Ikeda, Naoto Kobayashi +15
WINERED is a newly built high-efficiency (throughput) and high-resolution spectrograph customized for short NIR bands at 0.9-1.35 m. WINERED is equipped with a…
