A link between rocky exoplanet composition and stellar age
Angharad Weeks, Vincent Van Eylen, Daniel Huber +7
Interior compositions are key for our understanding of Earth-like exoplanets. The composition of the core can influence the presence of a magnetic dynamo and the strength of gravit…
Two Warm Super-Earths Transiting the Nearby M Dwarf TOI-2095
Elisa V. Quintana, Emily A. Gilbert, Thomas Barclay +55
We report the detection and validation of two planets orbiting TOI-2095 (TIC 235678745). The host star is a 3700K M1V dwarf with a high proper motion. The star lies at a distance o…
Revising Properties of Planet-Host Binary Systems. III. There is No Observed Radius Gap For Kepler Planets in Binary Star Systems
Kendall Sullivan, Adam L. Kraus, Daniel Huber +7
Binary stars are ubiquitous; the majority of solar-type stars exist in binaries. Exoplanet occurrence rate is suppressed in binaries, but some multiples do still host planets. Bina…
The Gaia-Kepler-TESS-Host Stellar Properties Catalog: Uniform Physical Parameters for 7993 Host Stars and 9324 Planets
Travis A. Berger, Joshua E. Schlieder, Daniel Huber
We present the first homogeneous catalog of , , and host stars and the corresponding catalog of exoplanet properties, which contain 7993 stars and 9324 planets,…
Planet Engulfment Detections are Rare According to Observations and Stellar Modeling
Aida Behmard, Fei Dai, John M. Brewer +2
Dynamical evolution within planetary systems can cause planets to be engulfed by their host stars. Following engulfment, the stellar photosphere abundance pattern will reflect accr…
The Discovery of a Planetary Companion Interior to Hot Jupiter WASP-132 b
Benjamin J. Hord, Knicole D. Colón, Travis A. Berger +21
Hot Jupiters are generally observed to lack close planetary companions, a trend that has been interpreted as evidence for high-eccentricity migration. We present the discovery and…
Zodiacal Exoplanets in Time (ZEIT) XII: A Directly-Imaged Planetary-Mass Companion to a Young Taurus M Dwarf Star
E. Gaidos, T. Hirano, A. L. Kraus +21
We report the discovery of a resolved (0".9) substellar companion to a member of the 1-5 Myr Taurus star-forming region. The host star (2M0437) is a single mid-M type ($T_{eff}\app…
Slow Cooling and Fast Reinflation for Hot Jupiters
Daniel P. Thorngren, Jonathan J. Fortney, Eric D. Lopez +2
The unexpectedly large radii of hot Jupiters are a longstanding mystery whose solution will provide important insights into their interior physics. Many potential solutions have be…
The Occurrence of Rocky Habitable Zone Planets Around Solar-Like Stars from Kepler Data
Steve Bryson, Michelle Kunimoto, Ravi K. Kopparapu +79
We present occurrence rates for rocky planets in the habitable zones (HZ) of main-sequence dwarf stars based on the Kepler DR25 planet candidate catalog and Gaia-based stellar prop…
The Gaia-Kepler Stellar Properties Catalog. II. Planet Radius Demographics as a Function of Stellar Mass and Age
Travis A. Berger, Daniel Huber, Eric Gaidos +2
Studies of exoplanet demographics require large samples and precise constraints on exoplanet host stars. Using the homogeneous Kepler stellar properties derived using Gaia Data Rel…
Zodiacal Exoplanets in Time. X. The Orbit and Atmosphere of the Young "Neptune Desert"-Dwelling Planet K2-100b
E. Gaidos, T. Hirano, A. W. Mann +17
We obtained high-resolution infrared spectroscopy and short-cadence photometry of the 600-800 Myr Praesepe star K2-100 during transits of its 1.67-day planet. This Neptune-size obj…
Sensitivity Analyses of Exoplanet Occurrence Rates from Kepler and Gaia
Megan Shabram, Natalie Batalha, Susan E. Thompson +11
We infer the number of planets-per-star as a function of orbital period and planet size using archival data products with updated stellar properties from the Data R…
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…
The Curious Case of KOI 4: Confirming Kepler's First Exoplanet
Ashley Chontos, Daniel Huber, David W. Latham +13
The discovery of thousands of planetary systems by Kepler has demonstrated that planets are ubiquitous. However, a major challenge has been the confirmation of Kepler planet candid…
Revised Radii of Kepler Stars and Planets Using Gaia Data Release 2
Travis A. Berger, Daniel Huber, Eric Gaidos +1
One bottleneck for the exploitation of data from the mission for stellar astrophysics and exoplanet research has been the lack of precise radii and evolutionary states for…
Identifying Young Planet Host Stars from Keck-HIRES Spectra of Lithium
Travis A. Berger, Andrew W. Howard, Ann Merchant Boesgaard
The lithium doublet at 6708 Å provides an age diagnostic for main sequence FGK dwarfs. We measured the abundance of lithium in 1305 stars with detected transiting planets from the…
