What's in Your Transit? Towards Reliably Getting More Science from Exoplanet Transit Data

Samson J. Mercier, Julien de Wit, Benjamin V. Rackham

Exoplanetary science heavily relies on transit depth () measurements. Yet, as instrumental precision increases, the uncertainty on appears to increasingly drift from expecta…

Combined Exoplanet Mass and Atmospheric Characterization for Accelerated Exoplanetology

Julien de Wit, Sara Seager, Prajwal Niraula

Today's most detailed characterization of exoplanet atmospheres is accessible via transit spectroscopy (TS). Detecting transiting exoplanets only yields their size, and it is thus…

First JWST thermal phase curves of temperate terrestrial exoplanets reveal no thick atmosphere around TRAPPIST-1 b and c

Michaël Gillon, Elsa Ducrot, Taylor J. Bell +30

We report JWST/MIRI 15 m phase curves of TRAPPIST-1 b and c, revealing thermal emission consistent with their irradiation levels, assuming no efficient heat redistribution. We…

Stellar Models Also Limit Exoplanet Atmosphere Studies in Emission

Thomas J. Fauchez, Elsa Ducrot, Benjamin V. Rackham +3

Stellar contamination has long been recognized as a major bottleneck in transmission spectroscopy, limiting our ability to accurately characterize exoplanet atmospheres-particularl…

An Eccentric Sub-Neptune Moving Into the Evaporation Desert

Sydney Jenkins, Andrew Vanderburg, Ritika Sethi +31

Though missions such as Kepler, K2, and TESS have discovered 2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P3 days) orbits. T…

TOI-6508b: A massive transiting brown dwarf orbiting a low-mass star

K. Barkaoui, D. Sebastian, S. Zúñiga-Fernández +44

We report the discovery of a transiting brown dwarf orbiting a low-mass star, TOI-6508b. Today, only ~50 transiting brown dwarfs have been discovered. TOI-6508b was first detected…
