E. Martioli, R. P. Petrucci, E. Jofre +42
The sub-Jovian desert is a region in the mass-period and radius-period parameter space, typically encompassing short-period ranges between super-Earths and hot Jupiters, that exhib…
Gemini High-resolution Optical SpecTrograph (GHOST) at Gemini-South: Instrument performance and integration, first science, and next steps
V. M. Kalari, R. J. Diaz, G. Robertson +57
The Gemini South telescope is now equipped with a new high-resolution spectrograph called GHOST (the Gemini High-resolution Optical SpecTrograph). This instrument provides high-eff…
Searching for GEMS: Characterizing Six Giant Planets around Cool Dwarfs
Shubham Kanodia, Arvind F. Gupta, Caleb I. Canas +42
Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasing…
Mass determination of two Jupiter-sized planets orbiting slightly evolved stars: TOI-2420 b and TOI-2485 b
Ilaria Carleo, Oscar Barrágan, Carina M. Persson +67
Hot and warm Jupiters might have undergone the same formation and evolution path, but the two populations exhibit different distributions of orbital parameters, challenging our und…
