On the formation of retrograde S-type planets in binaries with a polar circumbinary disk
Cheng Chen, Philip J. Armitage, C. J. Nixon +2
Retrograde S-type planets have been observed in several binary systems, yet their formation pathway remains poorly understood. With high-resolution hydrodynamic simulations, we dem…
Disc precession in Be/X-ray binaries drives superorbital variations of outbursts and colour
Rebecca G. Martin, Philip A. Charles
Superorbital periods that are observed in the brightness of Be/X-ray binaries may be driven by a misaligned and precessing Be star disc. We examine how the precessing disc model ex…
AC Her: Evidence of the first polar circumbinary planet
Rebecca G. Martin, Stephen H. Lubow, David Vallet +2
We examine the geometry of the post-asymptotic giant branch (AGB) star binary AC Her and its circumbinary disk. We show that the observations describe a binary orbit that is perpen…
Tilted circumbinary planetary systems as efficient progenitors of free-floating planets
Cheng Chen, Rebecca G. Martin, Stephen H. Lubow +1
The dominant mechanism for generating free-floating planets has so far remained elusive. One suggested mechanism is that planets are ejected from planetary systems due to planet-pl…
Can a binary star host three giant circumbinary planets?
Cheng Chen, Rebecca G. Martin, C. J. Nixon
We investigate the orbital stability of a tilted circumbinary planetary system with three giant planets. The planets are spaced by a constant number () of mutual Hill radii in t…
Tidal truncation of circumplanetary disks fails above a critical disk aspect ratio
Rebecca G. Martin, Philip J. Armitage, Stephen H. Lubow +1
We use numerical simulations of circumplanetary disks to determine the boundary between disks that are radially truncated by the tidal potential, and those where gas escapes the Hi…
