RVTESS I: Modeling Asteroseismic Signals with Simultaneous Photometry and RVs

Jiaxin Tang, Sharon X. Wang, Yaguang Li +22

Detecting small planets via the radial velocity method remains challenged by signals induced by stellar variability, versus the effects of the planet(s). Here, we explore using Gau…

Precise Radial Velocities

Jennifer A. Burt, Xavier Dumusque, Samuel Halverson

Precise measurements of a star's radial velocity (RV) made using extremely stable, high resolution, optical or near infrared spectrographs can be used to determine the masses and o…

The NCORES Program: Precise planetary masses, null results, and insight into the planet mass distribution near the radius gap

David J. Armstrong, Ares Osborn, Remo Burn +39

NCORES was a large observing program on the ESO HARPS spectrograph, dedicated to measuring the masses of Neptune-like and smaller transiting planets discovered by the TESS satellit…

Effects of planetary mass uncertainties on the interpretation of the reflectance spectra of Earth-like exoplanets

Mario Damiano, Zachary Burr, Renyu Hu +2

Atmospheric characterization of Earth-like exoplanets through reflected light spectroscopy is a key goal for upcoming direct imaging missions. A critical challenge in this endeavor…

Preparing for the Early eVolution Explorer: Characterizing the photochemical inputs and transit detection efficiencies of young planets using multiwavelength flare observations by TESS and Swift

Ward S. Howard, Meredith A. MacGregor, Adina D. Feinstein +6

Ultraviolet flare emission can drive photochemistry in exoplanet atmospheres and even serve as the primary source of uncertainty in atmospheric retrievals. Additionally, flare ener…
