Giant Outer Transiting Exoplanet Mass (GOT ‘EM) Survey. IV. Long-term Doppler Spectroscopy for 11 Stars Thought to Host Cool Giant Exoplanets

open access: yesThe Astrophysical Journal Supplement Series
Discovering and characterizing exoplanets at the outer edge of the transit method’s sensitivity has proven challenging owing to geometric biases and the practical difficulties associated with acquiring long observational baselines.

Doomed Worlds. I. No New Evidence for Orbital Decay in a Long-term Survey of 43 Ultrahot Jupiters

open access: yesThe Planetary Science Journal
Ultrahot Jupiters (UHJs) are likely doomed by tidal forces to undergo orbital decay and eventual disruption by their stars, but the timescale over which this process unfolds is unknown. We present results from a long-term project to monitor UHJ transits.

TOI-1685 b Is a Hot Rocky Super-Earth: Updates to the Stellar and Planet Parameters of a Popular JWST Cycle 2 Target

open access: yesThe Astrophysical Journal Letters
We present an updated characterization of the TOI-1685 planetary system, which consists of a P _b = 0.69 day ultra-short-period super-Earth planet orbiting a nearby ( d = 37.6 pc) M2.5V star (TIC 28900646, 2MASS J04342248+4302148).

An Analytic Characterization of the Limb Asymmetry—Transit Time Degeneracy

open access: yesThe Astrophysical Journal
Atmospheres are not spatially homogeneous. This is particularly true for hot, tidally locked exoplanets with large day-to-night temperature variations, which can yield significant differences between the morning and evening terminators—known as limb ...
