GEMS JWST: Hold on to your HATS(-6 b), a sub-solar metallicity giant planet with water, methane and ammonia in its atmosphere
Giannina Guzmán Caloca, Caleb I. Cañas, Nicole L. Wallack +16
HATS-6 b is one of several recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) and is part of a JWST survey that aims to compare bulk and atmospheric properties of t…
A Panchromatic JWST Spectrum of a Giant Starspot on the Fully Convective M-dwarf TOI-3884
C. A. Murray, L. Garcia, B. V. Rackham +18
TOI-3884 b is a rare super-Neptune transiting a fully convective M dwarf that hosts a persistent giant polar spot. Because the planet occults this active region during every transi…
GEMS JWST: HATS-75 b -- A giant planet with a sub-solar metallicity atmosphere orbiting an M-dwarf
Reza Ashtari, Jacob Lustig-Yaeger, Jessica Libby-Roberts +12
HATS-75 b is one of the recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) with a transmission spectrum shaped by both its atmosphere and the active stellar surface…
GEMS JWST: A sub-Solar metallicity atmosphere for giant planet TOI-5293Ab orbiting a rapidly changing M-dwarf
Shubham Kanodia, Caleb I. Cañas, Jacob Lustig-Yaeger +13
The growing sample of Giant Exoplanets around M-dwarf Stars (GEMS) helps probe the extremes of giant planet formation. Comparing the properties of this sample with their FGK counte…
GEMS JWST: Transmission spectroscopy of TOI-5205b reveals significant stellar contamination and a metal-poor atmosphere
Caleb I. Cañas, Jacob Lustig-Yaeger, Shang-Min Tsai +21
Recent discoveries of transiting giant exoplanets () around M dwarfs (GEMS) present an opportunity to investigate their atmospheric compositions and…
The Role of Intrinsic Temperature and Vertical Mixing in Characterizing Sub-Neptune Atmospheres
Neha Dushyantha Kumar, Jessica E. Libby-Roberts, Caleb I. Canas +3
Sub-Neptune planets are often modeled with a dense rocky or metal-rich interior beneath a thick hydrogen/helium (H/He) atmosphere; though their bulk densities could also be explain…
