TOI-132 b: A short-period planet in the Neptune desert transiting a G-type star
Matías R. Díaz, James S. Jenkins, Davide Gandolfi +45
The Neptune desert is a feature seen in the radius-mass-period plane, whereby a notable dearth of short period, Neptune-like planets is found. Here we report the {\it TESS} discove…
An extremely low-density and temperate giant exoplanet
A. Santerne, L. Malavolta, M. R. Kosiarek +68
Transiting extrasolar planets are key objects in the study of the formation, migration, and evolution of planetary systems. In particular, the exploration of the atmospheres of gia…
TESS Reveals HD 118203 b to be a Transiting Planet
Joshua Pepper, Stephen R. Kane, Joseph E. Rodriguez +30
The exoplanet HD 118203 b, orbiting a bright (V = 8.05) host star, was discovered using the radial velocity method by da Silva et al. (2006), but was not previously known to transi…
Using HARPS-N to characterise the long-period planets in the PH-2 and Kepler-103 systems
Sophie C. Dubber, Annelies Mortier, Ken Rice +26
We present confirmation of the planetary nature of PH-2b, as well as the first mass estimates for the two planets in the Kepler-103 system. PH-2b and Kepler-103c are both long-peri…
Planet Hunters TESS I: TOI 813, a subgiant hosting a transiting Saturn-sized planet on an 84-day orbit
N. L. Eisner, O. Barragán, S. Aigrain +47
We report on the discovery and validation of TOI 813b (TIC 55525572 b), a transiting exoplanet identified by citizen scientists in data from NASA's Transiting Exoplanet Survey Sate…
Absence of a thick atmosphere on the terrestrial exoplanet LHS 3844b
Laura Kreidberg, Daniel D. B. Koll, Caroline Morley +16
Most known terrestrial planets orbit small stars with radii less than 60% that of the Sun. Theoretical models predict that these planets are more vulnerable to atmospheric loss tha…
A 9-Hr CV With One Outburst in 4 Years of Kepler Data
Zhifei Yu, John Thorstensen, Saul Rappaport +11
During a visual search through the Kepler main-field lightcurves, we have discovered a cataclysmic variable (CV) that experienced only a single 4-day long outburst over four years,…
EXOFASTv2: A public, generalized, publication-quality exoplanet modeling code
Jason D. Eastman, Joseph E. Rodriguez, Eric Agol +6
We present the next generation public exoplanet fitting software, EXOFASTv2. It is capable of fitting an arbitrary number of planets, radial velocity data sets, astrometric data se…
Planetesimals Around Stars with TESS (PAST): I. Transient Dimming of a Binary Solar Analog at the End of the Planet Accretion Era
E. Gaidos, T. Jacobs, D. LaCourse +16
We report detection of quasi-periodic (1.5 day) dimming of HD 240779, the solar-mass primary in a 5" visual binary (also TIC 284730577), by the Transiting Exoplanet Survey Satellit…
The Random Transiter -- EPIC 249706694/HD 139139
S. Rappaport, A. Vanderburg, M. H. Kristiansen +16
We have identified a star, EPIC 249706694 (HD 139139), that was observed during K2 Campaign 15 with the Kepler extended mission that appears to exhibit 28 transit-like events over…
TESS Hunt for Young and Maturing Exoplanets (THYME): A planet in the 45 Myr Tucana-Horologium association
Elisabeth R. Newton, Andrew W. Mann, Benjamin M. Tofflemire +49
Young exoplanets are snapshots of the planetary evolution process. Planets that orbit stars in young associations are particularly important because the age of the planetary system…
Growth Model Interpretation of Planet Size Distribution
Li Zeng, Stein B. Jacobsen, Dimitar D. Sasselov +13
The radii and orbital periods of 4000+ confirmed/candidate exoplanets have been precisely measured by the Kepler mission. The radii show a bimodal distribution, with two peaks corr…
