I am working on open questions in theoretical astrophysics. Recently my main focus is

  •  How do stars explode to produce supernovae?
  • What is the long time evolution of the three body problem (three masses with 1/r^2 Newtonian gravitational attraction)?

Amazingly, these two questions may be tightly connected.

Other questions include
Where do cosmic rays come from?
How do 1% of stars and (extrasolar) planets find themselves in tight systems with few day orbits?

I am looking for more students. Feel free to contact me by email or drop by my office.
