A search for water vapor plumes on Europa by spatially resolved spectroscopic observation using Subaru/IRCS
Jun Kimura, Taro Matsuo, Hitomi Kobayashi +4
We present near-infrared high-dispersion spectroscopic observations of Europa using the Infrared Camera and Spectrograph (IRCS) onboard the Subaru Telescope, seeking direct evidenc…
[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…
First Result for Dark Matter Search by WINERED
Wen Yin, Taiki Bessho, Yuji Ikeda +10
The identity of dark matter has been a mystery in astronomy, cosmology, and particle theory for about a century. Bessho, Ikeda, and Yin (2022), three of the current authors, propos…
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…
