Abstract:
The β Pictoris system with its debris disk and a massive giant
planet orbiting at ~=9AU represents an ideal laboratory for studying
giant planet formation and evolution as well as planet-disk
interactions. β Pic b can also help in testing brightness-mass
relations at young ages. Other planets, yet undetected, may of course
be present in the system.
We aim at directly constraining the mass of β Pic b and at
searching for additional jovian planets on orbits closer than
typically 2AU.
Description:
We used high-precision Harps data collected over eight years since
2003 to measure and analyse β Pic radial velocities.
