High-temperature transmission spectroscopy system for molecular pressure broadening measurements in exoplanetary atmospheric conditions
Ko Hosokawa, Takayuki Kotani, Hajime Kawahara, Yui Kawashima et autres
We developed a high-temperature gas-cell transmission spectroscopy system to measure molecular absorption line spectra under H2 and He atmospheric conditions relevant to exoplanets and brown dwarfs. The system combines a tunable near-infrared laser that covers 1525–1630 nm with a minimum scan step …
