The β Pictoris Moving Group
- B. Zuckerman, I. Song, M. Bessell, R. Webb
- Physics, Geology
- 30 October 2001
Following the 1983 IRAS detection and subsequent imaging of its extensive dusty circumstellar disk, β Pictoris became the prototypical and most studied example of a potential forming planetary…
Young Stars Near the Sun

- Physics
- 17 August 2004
▪ Abstract Until the late 1990s the rich Hyades and the sparse UMa clusters were the only coeval, comoving concentrations of stars known within 60 pc of Earth. Both are hundreds of millions of years…
A giant planet candidate near a young brown dwarf - Direct VLT/NACO observations using IR wavefront sensing
- G. Chauvin, A. Lagrange, P. Lowrance
- Physics, Geology
- 14 September 2004
We present deep VLT/NACO infrared imaging and spectroscopic observations of the brown dwarf 2MASSWJ 1207334−393254, obtained during our on-going adaptive optics survey of southern young, nearby…
Metal Lines in DA White Dwarfs
- B. Zuckerman, D. Koester, I. Reid, M. Hünsch
- Physics, Geology
- 10 October 2003
We report Keck telescope HIRES echelle observations of DA white dwarfs in a continuation of an extensive search for metals. These spectra are supplemented with new JHK magnitudes that are used to…
Giant Planet Companion to 2MASSW J1207334-393254
- G. Chauvin, A. Lagrange, P. Lowrance
- Physics, Geology
- 29 April 2005
We report new VLT/NACO imaging observations of the young, nearby brown dwarf 2MASSW J1207334-393254 and its suggested planetary mass companion (2M1207 b). Three epochs of VLT/NACO measurements…
The AB Doradus Moving Group
- B. Zuckerman, I. Song, M. Bessell
- Physics
- 23 August 2004
From radio to X-ray wavelengths, AB Doradus has been an intensively studied star. We have identified ~30 nearby star systems, each with one or more characteristics of youth, that are moving through…
X-ray and molecular emission from the nearest region of recent star formation.
- J. Kastner, B. Zuckerman, D. Weintraub, T. Forveille
- Physics, GeologyScience
- 4 July 1997
Being at least three times closer to Earth than any well-studied region of star formation, the TW Hya Association serves as a test-bed for the study of x-ray emission from young stars and the formation of planetary systems around sunlike stars.
A companion to AB Pic at the planet/brown dwarf boundary
- G. Chauvin, A. Lagrange, M. Bessell
- Geology, Physics
- 29 April 2005
We report deep imaging observations of the young, nearby star AB Pic, a member of the large Tucana-Horologium association. We have detected a faint, red source $5.5''$ South of the star with JHK …
Inhibition of giant-planet formation by rapid gas depletion around young stars
- B. Zuckerman, T. Forveille, J. Kastner
- Physics, GeologyNature
- 9 February 1995
Observations of the molecular gas surrounding 20 stars whose ages are likely to be in this range are reported, finding that the gas dissipates rapidly; after a few million years the mass remaining is typically much less than the mass of Jupiter.
THE TUCANA/HOROLOGIUM, COLUMBA, AB DORADUS, AND ARGUS ASSOCIATIONS: NEW MEMBERS AND DUSTY DEBRIS DISKS
- B. Zuckerman, Joseph H. Rhee, I. Song, M. Bessell
- Physics, Geology
- 2 April 2011
We propose 35 star systems within ∼70 pc of Earth as newly identified members of nearby young stellar kinematic groups; these identifications include the first A- and late-B-type members of the AB…
