Search for Giant Planets around White Dwarfs with HST, Spitzer, and VLT
S. Friedrich, H. Zinnecker, S. Correia +3
For the last three years we have performed a survey for young (<3 Gyrs) giant planets around nearby white dwarfs with HST, Spitzer, and VLT. Direct HST/NICMOS imaging of the seven…
A VLT/NACO Survey for Triple and Quadruple Systems among Visual Pre-Main Sequence Binaries
S. Correia, H. Zinnecker, Th. Ratzka +1
This paper describes a systematic search for high-order multiplicity among wide visual Pre-Main Sequence (PMS) binaries. We conducted an Adaptive Optics survey of a sample of 58 PM…
Disks around young stars with VLTI/MIDI
Roy van Boekel, Peter Abraham, Serge Correia +17
We report on observations of circumstellar disks around young stars that have been obtained with the MIDI instrument, which is mounted on the VLT Interferometer and operates in the…
