Pink Dwarfs and the Paths to Stardom: How Brown Dwarfs Pushed Above the Hydrogen Burning Limit Evolve
Jaime Luisi, John C. Forbes, Heather V. Rusk +1
Brown dwarfs that gain mass through binary interactions may be pushed above the boundary that divides brown dwarfs from low-mass stars: the hydrogen burning limit (HBL). Some of th…
Semi-analytic Orbits: A Practical Implementation of Lynden-Bell's Planar Orbits and Extension to Vertical Oscillations
John C. Forbes, Michele T. Bannister, Angus Forrest +2
We present a practical implementation of the perturbation theory derived by Lynden-Bell (2015) for describing, to arbitrary precision, the orbit of a particle in an arbitrary spher…
Enhanced Disruption of Axion Minihalos by Multiple Stellar Encounters in the Milky Way
Ian DSouza, Chris Gordon, John C. Forbes
If QCD axion dark matter formed post-inflation, axion miniclusters emerged from isocurvature fluctuations and later merged hierarchically into minihalos. These minihalos, potential…
Non-linear scattering of plane gravitational and electromagnetic waves
Breanna Camden, Chris Stevens, John Forbes
Fully non-linear, plane-symmetric exact solutions of the Einstein equations describing the scattering of gravitational and electromagnetic waves have existed for many years. For th…
