Lyot Coronagraphy at the Palomar and Phase-Mask Coronagraphy at the VLT
Abstract
In this paper, we report on observations of faint companions and circumstellar disks at the Palomar 200-inch telescope. As a result, we present successful detection of the low-mass companion to HR 7672 and of the dusty disk around HD 141569 using ground-based coronagraphy. Finally, we will present the first promising images obtained with a Four-Quadrant Phase-Mask coronagraph on NACO at the VLT.
