High-Resolution Dayside Spectroscopy of the Ultra-Hot Jupiter WASP-178b with GHOST/Gemini South
Caitlin E. Bell, Emily K. Deibert, Adam B. Langeveld +4
The study presents high‑resolution optical dayside emission spectroscopy of the ultra‑hot Jupiter WASP‑178b using Gemini South, detecting neutral iron emission that confirms a ther…
TESS Photometry and Radial Velocity Analysis of the sub-Neptune Exoplanet Ï Mensae c and the Wider Ï Mensae Planetary System
Skylar S. Larsen, Jake D. Turner, Nikole K. Lewis +10
The paper combines six years of TESS photometry with 22 years of radial‑velocity data to refine the orbital parameters and masses of the sub‑Neptune π Men c and its companion plane…
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…
The Actinide-Boost Star LAMOST J122216.85-063345.2: A Detailed R-process Abundance Study with Gemini-S/GHOST
Miji Jeong, Young Sun Lee, Vinicius M. Placco +15
We present a detailed chemical-abundance analysis of an actinide-boost ((Th/Dy) = -0.74) star, LAMOST J122216.85-063345.2 (J1222), a very metal-poor ([Fe/H] = -2.45) halo s…
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…
