: GHOST covers a wide wavelength range from 363 to 950 nm. This lets researchers detect different chemical species and thermal features in one observation.
GHOST has been used to study the dayside spectroscopy of WASP-189 b to improve its atmospheric models.
: Describe the Gemini GHOST instrument, including its resolution ( ) and spectral range. gost na asu tp
: Researchers use the GHOST Data Reduction Pipeline to process raw spectra. This removes instrumental noise and "telluric" (Earth's atmospheric) interference to isolate the planetary signal.
: Discuss the detected species and whether the T-P profile indicates an atmospheric inversion or a "non-inverted" (decreasing temperature with height) structure. High-resolution Dayside Spectroscopy of WASP-189 b : GHOST covers a wide wavelength range from 363 to 950 nm
: 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
: Explain the use of T-P profiles in atmospheric retrieval models and how cross-correlation techniques are applied to the GHOST data. : Describe the Gemini GHOST instrument, including its
The is for high-resolution optical spectroscopy. It studies exoplanet atmospheres to determine the vertical thermal structure, or T-P profile .
