TOI-6981 b: a transiting sub-Neptune at the water ice line
Madison G. Scott, Amaury H. M. J Triaud, Emily K. Pass +42
We present TOI-6981 b, a cold (Teq= 170.0 +/-4.5 K, assuming an Earth-like albedo) sub-Neptune (Rb=2.40+/-0.10 R_oplus) on a 60.8 day orbit around around its M4-type host star (R*=…
Calibration of an Analog-to-Digital Conversion Nonlinearity in JWST/NIRISS
Shashank Dholakia, Shishir Dholakia, Benjamin J. S. Pope +4
We quantify an unusual flux-dependent systematic which is periodic in raw counts in flight data from the James Webb Space Telescope's Near Infrared Imager and Slitless Spectrograph…
A Cool Earth-sized Planet Candidate Transiting a Tenth Magnitude K-dwarf From K2
Alexander Venner, Andrew Vanderburg, Chelsea X. Huang +7
The transit method is currently one of our best means for the detection of potentially habitable "Earth-like" exoplanets. In principle, given sufficiently high photometric precisio…
The mass of the exo-Venus Gliese 12 b, as revealed by HARPS-N, ESPRESSO, and CARMENES
Daisy A. Turner, Yoshi Nike Emilia Eschen, Felipe Murgas +60
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 th…
A catalog of binary stars from phase modulation in the first four years of TESS Mission photometry
Shishir Dholakia, Simon J. Murphy, Chelsea X. Huang +2
We present a catalog of binary companions to Scuti stars, detected through phase modulations of their pulsations in TESS data. Pulsation timing has provided orbits for hundreds…
A General, Differentiable Transit Model for Ellipsoidal Occulters: Derivation, Application, and Forecast of Planetary Oblateness and Obliquity Constraints with JWST
Shashank Dholakia, Shishir Dholakia, Benjamin J. S. Pope
Increasingly precise space-based photometry uncovers higher-order effects in transits, eclipses and phase curves which can be used to characterize exoplanets in novel ways. The sub…
Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS and CHEOPS
Shishir Dholakia, Larissa Palethorpe, Alexander Venner +33
We report on the discovery of Gliese 12 b, the nearest transiting temperate, Earth-sized planet found to date. Gliese 12 is a bright ( mag, mag) metal-poor M4V star…
Gaussian Processes and Nested Sampling Applied to Kepler's Small Long-period Exoplanet Candidates
Michael R. B. Matesic, Jason F. Rowe, John H. Livingston +3
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…
Efficient and precise transit light curves for rapidly-rotating, oblate stars
Shashank Dholakia, Rodrigo Luger, Shishir Dholakia
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…
A Substellar Companion to a Hot Star in K2's Campaign 0 Field
S. Dholakia, Ann Marie Cody, Steve B. Howell +6
The K2 mission has enabled searches for transits in crowded stellar environments very different from the original Kepler mission field. We describe here the reduction and analysis…
