The is for high-resolution optical spectroscopy. It studies exoplanet atmospheres to determine the vertical thermal structure, or T-P profile .
GHOST has been used to study the dayside spectroscopy of WASP-189 b to improve its atmospheric models.
: GHOST covers a wide wavelength range from 363 to 950 nm. This lets researchers detect different chemical species and thermal features in one observation. 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). Case Study: WASP-189 b Observations
A technical report or academic write-up on this topic could use the following structure: The is for high-resolution optical spectroscopy
The prompt "gost na asu tp" appears to refer to the high-resolution spectrograph at the Gemini South Observatory . This instrument observes exoplanets like WASP-189 b , focusing on their Temperature-Pressure (T-P) profiles. Overview of GHOST and T-P Profile Analysis
: Describe the Gemini GHOST instrument, including its resolution ( ) and spectral range. : GHOST covers a wide wavelength range from 363 to 950 nm
: Explain the use of T-P profiles in atmospheric retrieval models and how cross-correlation techniques are applied to the GHOST data.
