Retrograde Hot Jupiters from Secular Planet-Planet Interactions
Retrograde Hot Jupiters Secular Planet-Planet Interactions
2010/11/15
The search for extra-solar planets has led to the surprising discovery of many Jupiter-like planets in very close proximity to their host star1, the so-called “hot Jupiters.”
Retrograde Accretion and Merging Supermassive Black Holes
accretion accretion discs black hole physics galaxies formation – galaxies
2010/11/12
We investigate whether a circumbinary gas disc can coalesce a supermassive black hole
binary system in the centre of a galaxy. This is known to be problematic for a prograde disc.
We show that in co...
Orbital Orientations of Exoplanets: HAT-P-4b is Prograde and HAT-P-14b is Retrograde
Earth and Planetary Astrophysics (astro-ph.EP)

We present observations of the Rossiter-McLaughlin effect for two exoplanetary systems, revealing the orientations of their orbits relative to the rotation axes of their parent stars.
