Gaia Exoplanet Orbits, Demographics, and Evolution Survey (GEODES): Characteristics of Three Long-Period Companions Accelerating their Host Stars

Judah Van Zandt, Brendan Bowler, Erik Petigura +12

The upcoming release of DR4 will yield thousands of giant planet candidates, eventually enabling studies of giant planet eccentricities, masses, and occurrence rates across…

A Smooth Transition from Giant Planets to Brown Dwarfs from the Radial Occurrence Distribution

Judah Van Zandt, Greg Gilbert, Steven Giacalone +3

Measuring the occurrence rates of celestial objects is a valuable way to study their origins and evolution. Giant planets and brown dwarfs produce large Doppler signatures that are…

Extreme winds on the emerging dayside of an ultrahot Jupiter

Yapeng Zhang, Joost P. Wardenier, Aaron Householder +16

High-resolution spectroscopy provides a unique opportunity to directly probe atmospheric dynamics by resolving Doppler shifts of planetary signal as a function of orbital phases. U…

The Transition from Giant Planets to Brown Dwarfs beyond 1 au from the Stellar Metallicity Distribution

Steven Giacalone, Andrew W. Howard, Gregory J. Gilbert +3

Giant planets and brown dwarfs are thought to form via a combination of pathways, including bottom-up mechanisms in which gas is accreted onto a solid core and top-down mechanisms…

Orbital Eccentricities Suggest a Gradual Transition from Giant Planets to Brown Dwarfs

Gregory J. Gilbert, Judah Van Zandt, Erik A. Petigura +3

To date, hundreds of sub-stellar objects with masses between have been detected orbiting main-sequence stars. The current convention uses the deuterium-burning…

The TESS Grand Unified Hot Jupiter Survey. III. Thirty More Giant Planets

Samuel W. Yee, Joshua N. Winn, Joel D. Hartman +123

We present the discovery of 30 transiting giant planets that were initially detected using data from NASA's Transiting Exoplanet Survey Satellite (TESS) mission. These new planets…
