A free-floating planet population in the Galaxy?
Hans Zinnecker
Most young low-mass stars are born as binary systems, and circumstellar disks have recently been observed around the individual components of proto-binary systems (e.g. L1551-IRS5)…
The Evolution of Circumstellar Disks: Lessons from the VLT and ISO
Wolfgang Brandner, Dan Potter, Scott S. Sheppard +2
There is strong evidence that the planets in the solar system evolved from a disk-shaped solar nebula ~4.56 Gyr ago. By studying young stars in various evolutionary stages, one aim…
NGC 3603 - a Local Template for Massive Young Clusters
B. Brandl, W. Brandner, F. Eisenhauer +3
We present a study of the star cluster associated with the massive Galactic HII region NGC3603 based on near-IR broad-- and narrowband observations taken with ISAAC/VLT under excel…
The Flattened, Rotating Molecular Gas Core of Protostellar Jet HH 212
Jennifer Wiseman, Alwyn Wootten, Hans Zinnecker +1
The recently discovered protostellar jet known as HH212 is beautifully symmetric, with a series of paired shock knots and bow shocks on either side of the exciting source region, I…
