Negative superhumps in cataclysmic variables driven by retrograde apsidal disk precession
David Vallet, Rebecca G. Martin, Stephen H. Lubow +1
Negative superhumps are photometric modulations in cataclysmic variables with periods slightly shorter than the orbital period. They are usually attributed to retrograde nodal prec…
Coplanar circumbinary planets can be unstable to large tilt oscillations in the presence of an inner polar planet
Anna C. Childs, Rebecca G. Martin, Stephen Lepp +2
Mutually misaligned circumbinary planets may form in a warped or broken gas disc or from later planet-planet interactions. With numerical simulations and analytic estimates we expl…
Polar circumtriple planets and disks can only form close to a triple star
Stephen Lepp, Rebecca G. Martin, Stephen H. Lubow
Observations of protoplanetary disks around binary and triple star systems suggest that misalignments between the orbital plane of the stars and the disks are common. Motivated by…
Formation of super-Earths in icy dead zones around low-mass stars
David Vallet, Anna C. Childs, Rebecca G. Martin +2
While giant planet occurrence rates increase with stellar mass, occurrence rates of close-in super-Earths decrease. This is in contradiction to the expectation that the total mass…
Fast nodal precession of the disc around Pleione requires a broken disc
Rebecca G. Martin, Stephen Lepp
Pleione is a Be star that is in a 218 day orbit with a low-mass binary companion. Recent numerical simulations have shown that a Be star disc can be subject to breaking when materi…
A radial limit on polar circumbinary orbits from general relativity
Stephen Lepp, Rebecca G. Martin, Anna C. Childs
A particle orbiting a misaligned eccentric orbit binary undergoes nodal precession either around the binary angular momentum vector (a circulating orbit) or around a stationary inc…
