Positive superhumps in high mass ratio cataclysmic variables driven by apsidal disk precession
Rebecca G. Martin, Stephen H. Lubow, David Vallet +1
The paper uses 3D hydrodynamic simulations to show that cataclysmic variable disks can become eccentric and produce positive superhumps even when the 3:1 resonance lies outside the…
The Eccentric Disk Model for Superhumps
Stephen H. Lubow
An important goal of the disk instability model is to explain the superhump phenomenon. Superhumps are features found in the light curves of binary systems, characterized by a peri…
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…
The Impact of the MAST Data Archive
Richard A. Shaw, Jenny L. Novacescu, Sarah Weissman +31
The Barbara A. Mikulski Archive for Space Telescopes (MAST) hosts science-ready data products from over twenty NASA missions, plus community-contributed data collections, and other…
Primordial planet spin driven by boundary layer effects in a decretion disc
Rebecca G. Martin, Stephen H. Lubow, David Vallet +4
Accretion of material from a protoplanetary disc on to a forming giant planet can spin the planet up to close to its breakup rate, , where $M_…
Planet-disc interactions around eccentric binaries and misaligned ring formation
Rebecca G. Martin, Stephen H. Lubow
We explore the evolution of a giant planet that interacts with a circumbinary disc that orbits a misaligned binary by means of analytic models and hydrodynamical simulations. Plane…
