The is for high-resolution optical spectroscopy. It studies exoplanet atmospheres to determine the vertical thermal structure, or T-P profile .
: Describe the Gemini GHOST instrument, including its resolution ( ) and spectral range. gost na asu tp
: The T-P profile shows how temperature changes with atmospheric pressure. In "ultra-hot Jupiters" like WASP-189 b, this profile often shows a thermal inversion . The atmosphere gets hotter at higher altitudes because of the absorption of stellar radiation by species like titanium oxide (TiO) or iron (Fe).
