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…
On the orbital evolution of binaries with polar circumbinary disks
Cheng Chen, Philip J. Armitage, C. J. Nixon
Binaries occur in many astrophysical systems, from young protostellar binaries in star forming regions to supermassive black hole binaries in galaxy centers. In many cases, a circu…
On the origin of polar planets around single stars
Cheng Chen, Stanley A. Baronett, C. J. Nixon +1
The Rossiter-McLaughlin effect measures the misalignment between a planet's orbital plane and its host star's rotation plane. Around 10 of planets exhibit misalignments in the…
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…
