Improving exoplanet mass characterisation with Bayesian model selection using the Learned Harmonic Mean Estimator
Ross S. Dobson, Vincent Van Eylen, Ioanna Manolopoulou +1
Radial velocity (RV) analyses require modelling choices (such as eccentricity treatment, noise model, velocity trends, and number of planets) that can significantly affect derived…
Determining the Host Stars of Planets in Binary Star Systems with Asterodensity Profiling: Investigating the Canonical Radius Gap
Nathanael Burns-Watson, Kendall Sullivan, Adam Kraus
Over the past 30 years, thousands of exoplanets have been discovered, revealing detailed demographics of planets outside the Solar System. One of the most dramatic features of the…
Planetary Architectures of Kepler Compact Multis with Binary Star Companions
Kendall Sullivan, Gregory J. Gilbert
Planets in binary-star systems exhibit demographic differences compared to planets in single-star systems. In particular, planets with binary-star hosts have a lower overall occurr…
Barium Stars Across the Milky Way: Probing Their Origins via the GALAH Survey
Jaden Levine, Catherine Manea, Keith Hawkins +4
Barium stars are unusually enriched in barium ([Ba/Fe] >= 1.0 dex) and not predicted by current Galactic chemical evolution models. Previous observations of barium stars have found…
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…
Orbital Architectures of Planet-Hosting Binaries III. Testing Mutual Inclinations of Stellar and Planetary Orbits in Triple-Star Systems
Elise L. Evans, Trent J. Dupuy, Kendall Sullivan +7
Transiting planets in multiple-star systems, especially high-order multiples, make up a small fraction of the known planet population but provide unique opportunities to study the…
Revising Properties of Planet-Host Binary Systems. IV. The Radius Distribution of Small Planets in Binary Star Systems is Dependent on Stellar Separation
Kendall Sullivan, Adam L. Kraus, Travis A. Berger +10
Small planets () are divided into rocky super-Earths and gaseous sub-Neptunes separated by a radius gap, but the mechanisms that produce these distinct pla…
Starspots and Undetected Binary Stars Have Distinct Signatures in Young Stellar Associations
Kendall Sullivan, Adam L. Kraus
Young stars form in associations, meaning that young stellar associations provide an ideal environment to measure the age of a nominally coeval population. Isochrone fitting, which…
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…
Revising Properties of Planet-host Binary Systems II: Apparent Near-Earth Analog Planets in Binaries Are Often Sub-Neptunes
Kendall Sullivan, Adam L. Kraus
Identifying rocky planets in or near the habitable zones of their stars (near-Earth analogs) is one of the key motivations of many past and present planet-search missions. The cens…
Revising Properties of Planet-host Binary Systems I.: Methods and Pilot Study
Kendall Sullivan, Adam L. Kraus, Andrew W. Mann
To fully leverage the statistical strength of the large number of planets found by projects such as the Kepler survey, the properties of planets and their host stars must be measur…
Optical and Near-Infrared Excesses are Correlated in T Tauri Stars
Kendall Sullivan, Adam L. Kraus
Accretion is one of the defining characteristics of classical T Tauri stars, fueled by the presence of a circumstellar disk comprised of dust and gas. Accretion produces a UV and o…
Undetected Binary Stars Cause an Observed Mass Dependent Age Gradient in Upper Scorpius
Kendall Sullivan, Adam Kraus
Young stellar associations represent a key site for the study of star formation, but to accurately compare observations to models of stellar evolution, the age of an association mu…
Projected Rotational Velocities and Fundamental Properties of Low-Mass Pre-Main Sequence Stars in the Taurus-Auriga Star Forming Region
Larissa A. Nofi, Christopher M. Johns-Krull, Ricardo López-Valdivia +11
The projected stellar rotational velocity () is critical for our understanding of processes related to the evolution of angular momentum in pre-main sequence stars. We pr…
S and VV Corona Australis: Spectroscopic Variability in Two Young Binary Star Systems
Kendall Sullivan, L. Prato, Suzan Edwards +2
We used high-resolution near-infrared spectroscopy from the NIRSPEC instrument on the Keck II telescope, taken over multiple epochs spanning five years, to examine two young binary…
CO Detected in CI Tau b: Hot Start Implied by Planet Mass and M
Laura Flagg, Christopher M. Johns-Krull, Larissa Nofi +5
We acquired high resolution IR spectra of CI Tau, the host star of one of the few young planet candidates amenable to direct spectroscopic detection. We confirm the planet's existe…
CHANG-ES VIII: Uncovering Hidden AGN Activity in Radio Polarization
Judith A. Irwin, Philip Schmidt, A. Damas-Segovia +12
We report on C-band (5 - 7 GHz) observations of the galaxy, NGC~2992, from the CHANG-ES sample. This galaxy displays an embedded nuclear double-lobed radio morphology within its sp…
