The POKEMON Speckle Survey of Nearby M dwarfs. IV. Distance-Limited Catalog (POKEMON-DLC)
Catherine A. Clark, Zafar Rustamkulov, Gerard T. van Belle +5
The Solar Neighborhood is dominated by stars smaller, colder, and fainter than the Sun: the M dwarfs. If we are to understand the context in which the Sun formed and evolved, then…
The POKEMON Speckle Survey of Nearby M Dwarfs. III. The Stellar Multiplicity Rate of M Dwarfs within 15 pc
Catherine A. Clark, Gerard T. van Belle, Elliott P. Horch +8
M dwarfs are ubiquitous in our galaxy, and the rate at which they host stellar companions, and the properties of these companions, provides a window into the formation and evolutio…
The POKEMON Speckle Survey of Nearby M Dwarfs. II. Observations of 1125 Targets
Catherine A. Clark, Gerard T. van Belle, Elliott P. Horch +7
Stellar multiplicity is correlated with many stellar properties, yet multiplicity measurements have proven difficult for the M dwarfs -- the most common type of star in our galaxy…
Asteroseismology with the Roman Galactic Bulge Time-Domain Survey
Daniel Huber, Marc Pinsonneault, Paul Beck +24

A Dearth of Close-In Stellar Companions to M-dwarf TESS Objects of Interest
Catherine A. Clark, Gerard T. van Belle, David R. Ciardi +5
TESS has proven to be a powerful resource for finding planets, including those that orbit the most prevalent stars in our galaxy: the M dwarfs. Identification of stellar companions…
Direct Measurements of Giant Star Effective Temperatures and Linear Radii: Calibration Against Spectral Types and V-K Color

E. Furlan, D. R. Ciardi, M. E. Everett +16
We present results from high-resolution, optical to near-IR imaging of host stars of Kepler Objects of Interest (KOIs), identified in the original Kepler field. Part of the data we…
A Catalog of Calibrator Stars for Next-Generation Optical Interferometers
Samuel J. Swihart, E. Victor Garcia, Keivan G. Stassun +3
Benchmark stars with known angular diameters are key to calibrating interferometric observations. With the advent of optical interferometry, there is a need for suitably bright, we…
Spectroscopic and Interferometric Measurements of Nine K Giant Stars
