An Adaptive Optics Survey of M8-M9 Stars: Discovery of 4 Very Low mass Binaries With at Least One System Containing a Brown Dwarf Companion (2002)

Close, Laird M., Siegler, Nick, Potter, Dan, Brandner, Wolfgang, Liebert, James

Use of the highly sensitive Hokupa'a/Gemini curvature wavefront sensor has allowed for the first time direct adaptive optics (AO) guiding on M8-M9 very low mass (VLM) stars. An initial survey of 20...

The Evolution of Circumstellar Disks: Lessons from the VLT and ISO (2001)

Brandner, Wolfgang, Potter, Dan, Sheppard, Scott S., Moneti, Andrea, Zinnecker, Hans

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 aims at tracing back...

Observing the planet formation time-scale by ground-based direct imaging of planetary companions to young nearby stars: Gemini/Hokupa'a image of TWA-5 (2001)

Neuhaeuser, Ralph, Potter, Dan, Brandner, Wolfgang

Many extra-solar planets and a few planetary systems have been found indirectly by small periodic radial velocity variations around old nearby stars. The orbital characteristics of most of them are...
