The mass of the exo-Venus Gliese 12 b, as revealed by HARPS-N, ESPRESSO, and CARMENES Open
Small temperate planets are prime targets for exoplanet studies due to their possible similarities with the rocky planets in the Solar System. M dwarfs are promising hosts since the planetary signals are within our current detection capabi…

A General, Differentiable Transit Model for Ellipsoidal Occulters: Derivation, Application, and Forecast of Planetary Oblateness and Obliquity Constraints with JWST Open
Increasingly precise space-based photometry uncovers higher-order effects in transits, eclipses, and phase curves that can be used to characterize exoplanets in novel ways. The subtle signature induced by a rotationally deformed exoplanet …

A catalogue of binary stars from phase modulation in the first four years of <i>TESS</i> mission photometry Open
We present a catalogue of binary companions to $\delta$ Scuti stars, detected through phase modulations of their pulsations in Transiting Exoplanet Survey Satellite (TESS) data. Pulsation timing has provided orbits for hundreds of pulsatin…

A catalog of binary stars from phase modulation in the first four years of TESS Mission photometry Open
We present a catalog of binary companions to $δ$ Scuti stars, detected through phase modulations of their pulsations in TESS data. Pulsation timing has provided orbits for hundreds of pulsating stars in binaries from space-based photometry…

Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS and CHEOPS Open
We report on the discovery of Gliese 12 b, the nearest transiting temperate, Earth-sized planet found to date. Gliese 12 is a bright ($V=12.6$ mag, $K=7.8$ mag) metal-poor M4V star only $12.162\pm0.005$ pc away from the Solar System with o…

Gaussian Processes and Nested Sampling Applied to Kepler's Small Long-period Exoplanet Candidates Open
There are more than 5000 confirmed and validated planets beyond the solar system to date, more than half of which were discovered by NASA’s Kepler mission. The catalog of Kepler’s exoplanet candidates has only been extensively analyzed und…
View article: Efficient and Precise Transit Light Curves for Rapidly Rotating, Oblate Stars
Efficient and Precise Transit Light Curves for Rapidly Rotating, Oblate Stars Open
We derive solutions to transit light curves of exoplanets orbiting rapidly rotating stars. These stars exhibit significant oblateness and gravity darkening, a phenomenon where the poles of the star have a higher temperature and luminosity …

Efficient transit light curves for oblate and rapidly rotating stars Open
Exoplanets that transit rapidly-rotating stars can be a unique tool to learn about the dynamical history of exoplanet systems photometrically. Two rotational effects on such stars are oblateness and gravity darkening, where the poles are h…

Constraining Orbital Periods from Nonconsecutive Observations: Period Estimates for Long-period Planets in Six Systems Observed by K2 During Multiple Campaigns Open
Most planetary discoveries with the K2 and Transiting Exoplanet Survey Satellite ( TESS ) missions are restricted to short periods because of the limited duration of observation. However, the re-observation of sky area allows for the detec…
