General circulation models of gas giant exoplanets predict equatorial jets that drive inhomogeneities across the planetary atmosphere. We studied the transmission spectrum of the hot Jupiter WASP-127b during one transit […]

Orbital Obliquity of the Young Planet TOI-5398 b and the Evolutionary History of the System
Multi-planet systems exhibit remarkable architectural diversity. However, short-period giant planets are typically isolated. Compact systems like TOI-5398, with an outer close-orbit giant and an inner small-size planet, are rare among […]
Characterization of Starspots on a Young M-dwarf K2-25: Multi-band Observations of Stellar Photometric Variability and Planetary Transits
Detailed atmospheric characterization of exoplanets by transmission spectroscopy requires careful consideration of stellar surface inhomogeneities induced by starspots.
LHS 1140 b Is A Potentially Habitable Water World
LHS 1140 b is a small planet orbiting in the habitable zone of its M4.5V dwarf host. Recent mass and radius constraints have indicated that it has either a thick […]
Do Temperate Rocky Planets Around M Dwarfs have an Atmosphere?
Detecting an atmosphere on nearby temperate planets is one of the most important scientific objectives of the Webb mission, an endeavour in practice limited to a handful of well-characterized planets: […]
VIRA: An Exoplanet Atmospheric Retrieval Framework for JWST Transmission Spectroscopy
JWST observations are leading to important new insights into exoplanetary atmospheres through transmission spectroscopy.
Neptune-like Exoplanets Can Be Cloudy Or Clear — New Findings Suggest The Reason Why
The study of “exoplanets,” the sci-fi-sounding name for all planets in the cosmos beyond our own solar system, is a pretty new field. Mainly, exoplanet researchers like those in the […]
Inner Edge Habitable Zone Limits Around Main Sequence Stars: Cloudy Estimates
Understanding the limits of rocky planet habitability is one of the key goals of current and future exoplanet characterization efforts. An intrinsic concept of rocky planet habitability is the Habitable […]
Separated Twins Or Just Siblings? A Multi-planet System Around An M Dwarf Including A Cool sub-Neptune
We report the discovery of two TESS sub-Neptunes orbiting the early M dwarf TOI-904 (TIC 261257684). Both exoplanets, TOI-904 b and c, were initially observed in TESS sector 12 with […]
Clouds and Clarity: Revisiting Atmospheric Feature Trends in Neptune-size Exoplanets
Over the last decade, precise exoplanet transmission spectroscopy has revealed the atmospheres of dozens of exoplanets, driven largely by observatories like the Hubble Space Telescope.
