Quantifying the Contamination From Nearby Stellar Companions in Gaia DR3 Photometry
Kendall Sullivan, Adam L. Kraus, Travis A. Berger +1
Identifying and removing binary stars from stellar samples is a crucial but complicated task. Regardless of how carefully a sample is selected, some binaries will remain and compli…
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…
Stellar Models are Reliable at Low Metallicity: An Asteroseismic Age for the Ancient Very Metal-Poor Star KIC 8144907
Daniel Huber, Ditte Slumstrup, Marc Hon +15
Very metal-poor stars ([Fe/H]<-2) are important laboratories for testing stellar models and reconstructing the formation history of our galaxy. Asteroseismology is a powerful tool…
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…
Is [Y/Mg] a Reliable Age Diagnostic for FGK Stars?
Travis A. Berger, Jennifer L. van Saders, Daniel Huber +3
Current spectroscopic surveys are producing large catalogs of chemical abundances for stars of all types. The yttrium to magnesium ratio, [Y/Mg], has emerged as a candidate age ind…
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…
Rotation Distributions around the Kraft Break with TESS and Kepler: The Influences of Age, Metallicity, and Binarity
Ellis A. Avallone, Jamie N. Tayar, Jennifer L. van Saders +6
Stellar rotation is a complex function of mass, metallicity, and age and can be altered by binarity. To understand the importance of these parameters in main sequence stars, we hav…
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 Stars Kepler Missed: Investigating the Kepler Target Selection Function Using Gaia DR2
Linnea M. Wolniewicz, Travis A. Berger, Daniel Huber
The Kepler Mission revolutionized exoplanet science and stellar astrophysics by obtaining highly precise photometry of over 200,000 stars over 4 years. A critical piece of informat…
TESS Asteroseismology of Mensae: Benchmark Ages for a G7 Dwarf and its M-dwarf Companion
Ashley Chontos, Daniel Huber, Travis A. Berger +27
Asteroseismology of bright stars has become increasingly important as a method to determine fundamental properties (in particular ages) of stars. The Kepler Space Telescope initiat…
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…
Exploring the evolution of stellar rotation using Galactic kinematics
Ruth Angus, Angus Beane, Adrian M. Price-Whelan +9
The rotational evolution of cool dwarfs is poorly constrained after around 1-2 Gyr due to a lack of precise ages and rotation periods for old main-sequence stars. In this work we u…
Zodiacal Exoplanets in Time. X. The Orbit and Atmosphere of the Young "Neptune Desert"-Dwelling Planet K2-100b
