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…
Fast Radio Bursts and Interstellar Objects
Dang Pham, Matthew J. Hopkins, Chris Lintott +2
Fast radio bursts (FRBs) are transient radio events with millisecond-scale durations, and debated origins. Collisions between planetesimals and neutron stars have been proposed as…
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…
