High-resolution resonant portraits of a single-planet white dwarf system
Dimitri Veras, Nikolaos Georgakarakos, Ian Dobbs-Dixon
The dynamical excitation of asteroids due to mean motion resonant interactions with planets is enhanced when their parent star leaves the main sequence. However, numerical investig…
TESS Giants Transiting Giants III: An eccentric warm Jupiter supports a period-eccentricity relation for giant planets transiting evolved stars
Samuel K. Grunblatt, Nicholas Saunders, Ashley Chontos +27
The fate of planets around rapidly evolving stars is not well understood. Previous studies have suggested that relative to the main sequence population, planets transiting evolved…
Mathematical encoding within multi-resonant planetary systems as SETI beacons
Matthew S. Clement, Sean N. Raymond, Dimitri Veras +1
How might an advanced alien civilization manipulate the orbits within a planetary system to create a durable signpost that communicates its existence? While it is still debated whe…
Chaos over Order: Mapping 3D Rotation of Triaxial Asteroids and Minor Planets
Valeri V. Makarov, Alexey Goldin, Alexei V. Tkachenko +2
Celestial bodies approximated with rigid triaxial ellipsoids in a two-body system can rotate chaotically due to the time-varying gravitational torque from the central mass. At smal…
Birth cluster simulations of planetary systems with multiple super-Earths: initial conditions for white dwarf pollution drivers
Katja Stock, Dimitri Veras, Maxwell X. Cai +2
Previous investigations have revealed that eccentric super-Earths represent a class of planets which are particularly effective at transporting minor bodies towards white dwarfs an…
A white dwarf accreting planetary material determined from X-ray observations
Tim Cunningham, Peter J. Wheatley, Pier-Emmanuel Tremblay +4
The atmospheres of a large proportion of white dwarf stars are polluted by heavy elements that are expected to sink out of visible layers on short timescales. This has been interpr…
