Binaries in galactic nuclei and gravitational-wave sources
In Petrovich & Antonini 2017 we studied the orbital evolution of stellar binaries in our galactic center and proposed that a sizable...
White dwarf pollution by rocky bodies
A sizable fraction of both young and old white dwarfs (WDs) are found to have metals in their atmospheres. This is puzzling because...
Stability and fates of planetary systems
One important lesson that have learnt from the thousands of exoplanets discovered to date is that planetary systems often become...
High-eccentricity migration of hot and warm Jupiters
I worked on my thesis trying to understand how the hundreds of Jupiter-like planets discovered in short-period orbits (<10 days, the...
Kepler planets around resonances: in-situ planet formation
The orbital architecture of multi-planet systems discovered by Kepler encode information about their formation history and evolution. One...
Disk-satellite interactions
We revisit some fundamental aspects of the theory of disk-satellite interaction and address the questions of how is the tidal torque...
Thermal evolution of old neutron stars
From the standard Neutron Star cooling theory after we expect that after ~10 million years the initially very hot stars have to cooled...
