ExoGemS High-Resolution Transmission Spectroscopy of WASP-76b with GRACES
Emily K. Deibert, Ernst J. W. de Mooij, Ray Jayawardhana +9
We present high-resolution transmission spectroscopy of WASP-76b with GRACES/Gemini North obtained as part of the ExoGemS survey. With a broad spectral range of 400-1050 nm and a r…
ExoGemS Detection of a Metal Hydride in an Exoplanet Atmosphere
Laura Flagg, Jake D. Turner, Emily Deibert +7
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 exoplan…
A spectroscopic thermometer: individual vibrational band spectroscopy with the example of OH in the atmosphere of WASP-33b
Sam O. M. Wright, Stevanus K. Nugroho, Matteo Brogi +26
Individual vibrational band spectroscopy presents an opportunity to examine exoplanet atmospheres in detail by distinguishing where the vibrational state populations of molecules d…
High-resolution Emission Spectroscopy of the Ultrahot Jupiter KELT-9b: Little Variation in Day- and Nightside Emission Line Contrasts
Andrew Ridden-Harper, Ernst de Mooij, Ray Jayawardhana +3
The transmission spectrum of the ultrahot Jupiter KELT-9b ( 4000 K) exhibits absorption by several metal species. We searched for atomic and molecular lines in its e…
