Report by the ESA-ESO Working Group on Extra-Solar Planets
M. Perryman, O. Hainaut, D. Dravins +14
Various techniques are being used to search for extra-solar planetary signatures, including accurate measurement of radial velocity and positional (astrometric) displacements, grav…
Dust disks around old Pre Main-Sequence stars: HST/NICMOS2 scattered light images and modeling
J. C. Augereau, A. M. Lagrange, D. Mouillet +1
We present recent near-infrared detections of circumstellar disks around the two old PMS Herbig stars HD 141569 and HD 100546 obtained with the HST/NICMOS2 camera. They reveal exte…
Possible spectral lines from the gaseous Beta Pictoris disk
A. Lecavelier des Etangs, L. M. Hobbs, A. Vidal-Madjar +6
We present the results of exploratory HST observations to detect the emission lines of ions in the Beta Pic disk with the spectrograph slit placed off the star. Possible emission l…
On the HR 4796A circumstellar disk
J. C. Augereau, A. M. Lagrange, D. Mouillet +2
We investigate in details the properties of the disk surrounding the 8 Myr old star HR 4796A, one of the few stars bringing precious clues to better understand the scenario which l…
