Ultrahot Jupiters are gas giants that orbit so close to their host star that they are tidally
locked, causing a permanent hot dayside and a cooler nightside. Signatures of their …

Ultrahot Jupiters are ideal candidates to explore with high-resolution emission spectra.
Detailed theoretical studies are necessary to investigate the range of spectra that we can …

Exoplanet atmosphere studies are often enriched by synergies with brown dwarf analogs.
However, many key molecules commonly seen in brown dwarfs have yet to be confirmed in …

High-resolution spectra are unique indicators of three-dimensional (3D) processes in
exoplanetary atmospheres. For instance, in 2020, Ehrenreich et al. reported transmission …

Ultra-hot Jupiters are highly irradiated gas giant exoplanets on close-in orbits around their
host stars. The dayside atmospheres of these objects strongly emit thermal radiation due to …

Due to their likely tidally synchronized nature,(ultra) hot Jupiter atmospheres should
experience strongly spatially heterogeneous instellation. The large irradiation contrast and …

High-resolution spectroscopy has allowed for unprecedented levels of atmospheric
characterization, especially for the hottest gas-giant exoplanets known as ultrahot Jupiters …

We report an attempt to detect molecular and atomic species in the atmosphere of the
ultrahot Jupiter WASP-33b using the high-resolution echelle spectrograph NEID with a …

We present high-resolution transmission spectroscopy of WASP-76b with Gemini Remote
Access to CFHT ESPaDOnS Spectrograph (GRACES)/Gemini North obtained as part of the …

High-resolution spectroscopy has proven to be a powerful avenue for atmospheric remote
sensing of exoplanets. Recently, ESO commissioned the CRIRES+ high-resolution infrared …
