Were the Obliquities in DI Herculis Excited by an Unseen Tertiary Companion?
Kassandra R. Anderson, Joshua N. Winn
The eclipsing binary DI Herculis garnered interest for several decades because of an apparent disagreement between the observed and calculated values of the apsidal precession rate…
Further Evidence for Tidal Spin-Up of Hot Jupiter Host Stars
Roberto A. Tejada Arevalo, Joshua N. Winn, Kassandra R. Anderson
For most hot Jupiters around main-sequence Sun-like stars, tidal torques are expected to transfer angular momentum from the planet's orbit to the star's rotation. The timescale for…
On a Possible Solution to the Tidal Realignment Problem for Hot Jupiters
Kassandra R. Anderson, Joshua N. Winn, Kaloyan Penev
Hot stars with hot Jupiters have a wide range of obliquities, while cool stars with hot Jupiters tend to have low obliquities. An enticing explanation for this pattern is tidal rea…
Excitation of Spin-Orbit Misalignments in Stellar Binaries with Circumbinary Disks: Application to DI Herculis
Kassandra R. Anderson, Dong Lai
The large spin-orbit misalignments in the DI Herculis stellar binary system have resolved the decades-long puzzle of the anomalously slow apsidal precession rate, but raise new que…
Giant Planet Scatterings and Collisions: Hydrodynamics, Merger-Ejection Branching Ratio, and Properties of the Remnants
Jiaru Li, Dong Lai, Kassandra R. Anderson +1
Planetary systems with sufficiently small orbital spacings can experience planetary mergers and ejections. The branching ratio of mergers vs ejections depends sensitively on the tr…
In-Situ Scattering of Warm Jupiters and Implications for Dynamical Histories
Kassandra R. Anderson, Dong Lai, Bonan Pu
Many warm Jupiters (WJs) have substantial eccentricities, which are linked to their formation and migration histories. This paper explores eccentricity excitation of WJs due to pla…
