Scientific paper

We present new direct imaging results on the planet and debris disk surrounding 12 Myr-old beta Pictoris. Using an updated version of our reduction pipeline, we extract a new detection of beta Pic b from 2008 VLT/NaCo data at a sub-Jupiter projected separation ( 4 AU), about 1.5 lambda/D. We also obtain a high signal-to-noise rereduction of L' data taken in 2009 December. Intriguingly, the planet's orbit is aligned with the major axis of the outer disk (Omega 31 deg) but is probably misaligned with the warp/inclined disk at 80 AU, often cited as a signpost for the planet's existence. We also present new images of the beta Pic debris disk and discuss any evidence for a 2nd massive gas giant planet in the system.
