High angular resolution detection of β Pictoris b at 2.18 μm
Abstract
Context. A giant planet was recently discovered around the young star
Aims: Previous detections were made in the L' band (3.8 μm) and at 4.05 μm. We recorded new Ks-band data (2.18 μm) in order to measure its color and get an additional estimate of its mass and effective temperature
Methods: Angular differential Ks-band images of
Results: The companion is detected at Ks. This independently confirms the physical nature of
