Multiple scales analysis of a nonlinear timestepping instability in simulations of solitons
Benjamin A. Hyatt, Daniel Lecoanet, Evan H. Anders +1
The susceptibility of timestepping algorithms to numerical instabilities is an important consideration when simulating partial differential equations (PDEs). Here we identify and a…

Encounter circumstances of asteroid 99942 Apophis with the catalogue of known asteroids
Paul Wiegert, Ben Hyatt
Asteroid 99942 Apophis will pass near the Earth in April 2029. Expected to miss our planet by a safe margin, that could change if Apophis' path was perturbed by a collision with an…

The photometric variability of massive stars due to gravity waves excited by core convection
Evan H. Anders, Daniel Lecoanet, Matteo Cantiello +8
Massive stars die in catastrophic explosions, which seed the interstellar medium with heavy elements and produce neutron stars and black holes. Predictions of the explosion's chara…
