The angle between stellar spin axis and planetary orbital plane can provide key insights into the formation and dynamical evolution of planetary systems. In particular, this measur…
New and Updated Rossiter-McLaughlin Measurements for Three Hot Jupiter-Hosting M Dwarfs
Drew Weisserman, Ryan Cloutier, Alexandra Rochon +12
Evidence suggests that Kozai-Lidov high-eccentricity migration (HEM) is the dominant migration channel for short-period Giant Exoplanets around M dwarf Stars (GEMS). However, it is…

Skylar S. Larsen, Jake D. Turner, Nikole K. Lewis +10
Exoplanet characterization relies on precise measurements of planetary orbital and physical parameters. This is particularly important for planetary dynamics and atmospheric evolut…
The breaking of cold traps and onset of titanium in ultra-hot Jupiter atmospheres: WASP-189b in context
Stefan Pelletier, Romain Allart, Valentina Vaulato +56
Condensates are ubiquitous to all Solar System planets with significant (10mbar) atmospheres. The same is true for most exoplanets with characterised atmospheres, with even ultr…
The Roasting Marshmallows Program with IGRINS on Gemini South V: Atmosphere of MASCARA-1b is Enriched in Refractory Elements
Krishna Kanumalla, Michael R. Line, Martina Chiarella +75
Ultra-hot Jupiters (UHJs; K) enable simultaneous detection of volatile (ice-forming) and refractory (rock-forming) species in planetary atmospheres, provi…
Aligned Stellar Obliquities for Two Hot Jupiter-hosting M Dwarfs Revealed by MAROON-X: Implications for Hot Jupiter Formation
Drew Weisserman, Erik Gillis, Ryan Cloutier +14
Hot Jupiters (HJs) are less common around early M dwarfs than around AFGK stars, suggesting that HJs may form and/or migrate via distinct pathways around different type…
ExoGemS The Effect of Offsets from True Orbital Parameters on Exoplanet High-Resolution Transmission Spectra
Yasmine J. Meziani, Laura Flagg, Jake D. Turner +4
High-resolution spectroscopy (HRS) plays a crucial role in characterizing exoplanet atmospheres, revealing detailed information about their chemical composition, temperatures, and…
A Time-Resolved High-Resolution Spectroscopic Analysis of Ionized Calcium and Dynamical Processes in the Ultra-Hot Jupiter HAT-P-70 b
Adam B. Langeveld, Emily K. Deibert, Mitchell E. Young +5
We present the first transmission spectroscopy study of an exoplanet atmosphere with the high-resolution mode of the new Gemini High-resolution Optical SpecTrograph (GHOST) instrum…
High-Resolution Dayside Spectroscopy of WASP-189b: Detection of Iron during the GHOST/Gemini South System Verification Run
Emily K. Deibert, Adam B. Langeveld, Mitchell E. Young +30
With high equilibrium temperatures and tidally locked rotation, ultra-hot Jupiters (UHJs) are unique laboratories within which to probe extreme atmospheric physics and chemistry. I…
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…
Homogeneous search for helium in the atmosphere of 11 gas giant exoplanets with SPIRou
R. Allart, P. -B. Lemée-Joliecoeur, A. Y. Jaziri +31
The metastable helium triplet in the near-infrared (10833Å) is among the most important probes of exoplanet atmospheres. It can trace their extended outer layers and constrain mass…
Keck, Gemini, and Palomar 200-inch visible photometry of red and very-red Neptunian Trojans
