THYME XIII: Two young Neptunes orbiting a 75-Myr star in the Alpha Persei Cluster

Anne Dattilo, Andrew M. Vanderburg, Madyson G. Barber +28

Young planets with mass measurements are particularly valuable in studying atmospheric mass-loss processes, but these planets are rare and their masses difficult to measure due to…

Planet Masses, Radii, and Orbits from NASA's K2 Mission

Andrew W. Howard, Evan Sinukoff, Sarah Blunt +50

We report the masses, sizes, and orbital properties of 86 planets orbiting 55 stars observed by NASA's K2 Mission with follow-up Doppler measurements by the HIRES spectrometer at t…

A Pair of Dynamically Interacting Sub-Neptunes Around TOI-6054

Maxwell A. Kroft, Thomas G. Beatty, Ian J. M. Crossfield +31

We confirm the planetary nature of a pair of transiting sub-Neptune exoplanets orbiting the bright F-type sub-giant star TOI-6054 (, ) as a part of the OrCAS radia…

The TESS-Keck Survey XXIV: Outer Giants may be More Prevalent in the Presence of Inner Small Planets

Judah Van Zandt, Erik A. Petigura, Jack Lubin +38

We present the results of the Distant Giants Survey, a three-year radial velocity (RV) campaign to search for wide-separation giant planets orbiting Sun-like stars known to host an…

OrCAS: Origins, Compositions, and Atmospheres of Sub-neptunes. I. Survey Definition

Ian J. M. Crossfield, Alex S. Polanski, Paul Robertson +61

Sub-Neptunes - volatile-rich exoplanets smaller than Neptune - are intrinsically the most common type of planet known. However, the formation and nature of these objects, as well a…

Utilizing Photometry from Multiple Sources to Mitigate Stellar Variability in Precise Radial Velocities: A Case Study of Kepler-21

Corey Beard, Paul Robertson, Mark R. Giovinazzi +26

We present a new analysis of Kepler-21, the brightest (V = 8.5) Kepler system with a known transiting exoplanet, Kepler-21 b. Kepler-21 b is a radius valley planet ($R = 1.6\pm 0.2…
