TOI-640 b is one of only three known hot Jupiters to have a highly inflated radius (R$_{\rm P}$ > 1. 7R$_{\rm J}$, possibly a result of its host star's evolution) and resides on an orbit with a period longer than 5 days.

We report the discovery of two short-period Saturn-mass planets, one transiting the G subgiant TOI-954 (TIC 44792534, $ V = 10. 343 $, $ T = 9. 78 $) observed in TESS Sectors 4 & 5, and one transiting the G dwarf EPIC 246193072 ($ V = 12. 70 $, $ K = 10. 67 $) observed in K2 Campaigns 12 & 19.

Indications for very high metallicity and absence of methane for the eccentric exo-Saturn WASP-117b

Using a 1D atmosphere model with isothermal temperature, uniform cloud deck and equilibrium chemistry, the Bayesian evidence of a retrieval analysis of the transmission spectrum indicates a preference for a high atmospheric metallicity ${\rm [Fe/H]}=2. 58^{+0. 26}_{-0. 37}$ and clear skies.

Estimation of singly-transiting K2 planet periods with Gaia parallaxes

2 code implementations22 Aug 2019 Emily Sandford, Néstor Espinoza, Rafael Brahm, Andrés Jordán

When a planet is only observed to transit once, direct measurement of its period is impossible.

Discovery and Validation of a High-Density sub-Neptune from the K2 Mission

We report the discovery of BD+20594b, a high density sub-Neptune exoplanet, made using photometry from Campaign 4 of the two-wheeled Kepler (K2) mission, ground-based radial velocity follow-up from HARPS and high resolution lucky and adaptive optics imaging obtained using AstraLux and MagAO, respectively.

Limb darkening and exoplanets: testing stellar model atmospheres and identifying biases in transit parameters

3 code implementations24 Mar 2015 Néstor Espinoza, Andrés Jordán

Limb-darkening is fundamental in determining transit lightcurve shapes, and is typically modeled by a variety of laws that parametrize the intensity profile of the star that is being transited.
