Submillimetre images of dusty debris around nearby stars
Wayne S. Holland,Jane Greaves,Barry Zuckerman,R. A. Webb,C. McCarthy,I. M. Coulson,D. Walther,William R. M. Dent,Walter Kieran Gear,Ian Robson +9 more
TL;DR: In this paper, the presence of the central cavity, approximately the size of Neptune's orbit, was detected in the emission from Fomalhaut, beta Pictoris and Vega, which may be the signature of Earth-like planets.
Journal ArticleDOI
Discovery of Seven T Tauri Stars and a Brown Dwarf Candidatein the Nearby TW Hydrae Association
R. A. Webb,Barry Zuckerman,Imants Platais,Jennifer Patience,Russel White,M. J. Schwartz,C. McCarthy +6 more
TL;DR: The TW Hydrae Association as discussed by the authors was established by the discovery of five T Tauri star systems, two of which are resolved binaries, in the vicinity of the nearest known region of recent star formation.

Discovery of seven T Tauri stars and a brown dwarf candidate in the nearby TW Hydrae Association
R. A. Webb,Ben Zuckerman,Imants Platais,Jennifer Patience,Russel White,M. J. Schwartz,C. McCarthy +6 more
TL;DR: The TW Hydrae Association as discussed by the authors is a bona fide T Tauri association, unique in its proximity to Earth and its complete isolation from any known molecular clouds, and it has been used for future studies of the dissipation and formation of brown dwarfs and planets.

A Dust Ring around epsilon Eridani: Analog to the Young Solar System
Jane Greaves,W. S. Holland,Gerald Moriarty-Schieven,Tim Jenness,W. R. F. Dent,Barry Zuckerman,C. McCarthy,R. A. Webb,Harold M. Butner,Walter Kieran Gear,H. J. Walker +10 more
TL;DR: In this article, a new submillimeter camera was used to image the nearby star epsilon Eridani, where a ring of dust is seen peaking at 60 AU from the star and with much lower emission inside 30 AU, and the total mass of the ring is at least ~0.01 M⊕ in dust.

Jane Greaves,W. S. Holland,Gerald Moriarty-Schieven,T. Jenness,W. R. F. Dent,Ben Zuckerman,C. McCarthy,R. A. Webb,Harold M. Butner,Walter Kieran Gear,H. J. Walker +10 more
TL;DR: In this paper, a new submillimetre camera (SCUBA) was used at the JCMT at 850 microns wavelength to detect a ring of dust, peaking at 60 AU from the star and with much lower emission inside 30 AU.
