Signs of Similar Stellar Obliquity Distributions for Hot and Warm Jupiters Orbiting Cool Stars
Marvin Morgan, Brendan P. Bowler, Quang H. Tran +3
Transiting giant planets provide a natural opportunity to examine stellar obliquities, which offer clues about the origin and dynamical histories of close-in planets. Hot Jupiters…
A Large and Variable Leading Tail of Helium in a Hot Saturn Undergoing Runaway Inflation
Michael Gully-Santiago, Caroline V. Morley, Jessica Luna +14
Atmospheric escape shapes the fate of exoplanets, with statistical evidence for transformative mass loss imprinted across the mass-radius-insolation distribution. Here we present t…
Giant Tidal Tails of Helium Escaping the Hot Jupiter HAT-P-32 b
Zhoujian Zhang, Caroline V. Morley, Michael Gully-Santiago +14
Capturing planets in the act of losing their atmospheres provides rare opportunities to probe their evolution history. Such analysis has been enabled by observations of the helium…
Joint Modeling of Radial Velocities and Photometry with a Gaussian Process Framework
Quang H. Tran, Megan Bedell, Daniel Foreman-Mackey +1
Developments in the stability of modern spectrographs have led to extremely precise instrumental radial velocity (RV) measurements. For most stars, the detection limit of planetary…
Astrometric Accelerations as Dynamical Beacons: A Giant Planet Imaged Inside the Debris Disk of the Young Star AF Lep
Kyle Franson, Brendan P. Bowler, Yifan Zhou +13
We present the direct imaging discovery of a giant planet orbiting the young star AF Lep, a 1.2 member of the 24 3 Myr Pic moving group. AF Lep was observed a…
Rotation Periods, Inclinations, and Obliquities of Cool Stars Hosting Directly Imaged Substellar Companions: Spin-Orbit Misalignments are Common
Brendan P. Bowler, Quang H. Tran, Zhoujian Zhang +10
The orientation between a star's spin axis and a planet's orbital plane provides valuable information about the system's formation and dynamical history. For non-transiting planets…
