Submillimetre images of dusty debris around nearby stars
Indirect detections of massive — presumably Jupiter-like — planets orbiting nearby Sun-like stars have recently been reported,. Rocky, Earth-like planets are much more difficult to detect, but clues
In this paper a simple model for the steady state evolution of debris disks due to collisions is developed and confronted with the properties of the emerging population of seven Sun-like stars that
CO emission from discs around isolated HAeBe and Vega-excess stars
We describe results from a survey for J = 3‐2 12 CO emission from visible stars classified as having an infrared excess. The line is clearly detected in 21 objects, and significant molecular gas (10
A Dust Ring around epsilon Eridani: Analog to the Young Solar System
Dust emission around the nearby star Eridani has been imaged using a new submillimeter camera (the Submillimetre Common-User Bolometer Array at the James Clerk Maxwell Telescope). At an 850 μm
Steady State Evolution of Debris Disks around A Stars
In this paper a simple analytical model for the steady-state evolution of debris disks due to collisions is confronted with Spitzer observations of dust around main sequence A stars. All stars are
Herschel images of Fomalhaut: an extrasolar Kuiper belt at the height of its dynamical activity
Context. Fomalhaut is a young (2 ± 1 × 10 8 years), nearby (7.7 pc), 2 Mstar that is suspected to harbor an infant planetary system, interspersed with one or more belts of dusty debris. Aims. We
Models of the dust structures around Vega-excess stars
ABSTRA C T We present models of the submillimetre dust emission around four Vega-excess stars. The results are adjusted to fit simultaneously the spectral energy distribution from millimetre through
A deep submillimeter survey of the Galactic center
We present first results from a submillimeter continuum survey of the Galactic center central molecular zone (CMZ), made with the Submillimeter Common-User Bolometer Array (SCUBA) on the James Clerk
Spiral density waves in a young protoplanetary disk
Using the Atacama Large Millimeter/submillimeter Array, a pair of trailing symmetric spiral arms are detected in the protoplanetary disk surrounding the young star Elias 2-27, suggesting shocks of spiral density waves in the midplane of this young disk.
Molecular Gas Clumps from the Destruction of Icy Bodies in the β Pictoris Debris Disk
A highly asymmetric disk of dust and carbon monoxide orbiting the planet-hosting star, β Pictoris, delineates a region of enhanced collisions, either from a mean motion resonance with an unseen giant planet or from the remnants of a collision of Mars-mass planets.
