Early evidence for isotropic planetary obliquities in young super-Jupiter systems
Michael Poon, Marta L. Bryan, Hanno Rein +3
This decade has seen the first measurements of extrasolar planetary obliquities, characterizing how an exoplanet's spin axis is oriented relative to its orbital axis. These measure…
A potential exomoon from the predicted planet obliquity of Pictoris b
Michael Poon, Hanno Rein, Dang Pham
Planet obliquity is the alignment or misalignment of a planet spin axis relative to its orbit normal. In a multiplanet system, this obliquity is a valuable signature of planet form…
Polluting White Dwarfs with Oort Cloud Comets
Dang Pham, Hanno Rein
Observations point to old white dwarfs (WDs) accreting metals at a relatively constant rate over 8~Gyrs. Exo-Oort clouds around WDs have been proposed as potential reservoirs of ma…
A new timestep criterion for N-body simulations
Dang Pham, Hanno Rein, David S. Spiegel
We derive a new criterion for estimating characteristic dynamical timescales in N-body simulations. The criterion uses the second, third, and fourth derivatives of particle positio…
