An Unbiased Survey of 500 Nearby Stars for Debris Disks: A JCMT Legacy Program
B. C. Matthews, J. S. Greaves, W. S. Holland +28
We present the scientific motivation and observing plan for an upcoming detection survey for debris disks using the James Clerk Maxwell Telescope. The SCUBA-2 Unbiased Nearby Stars…
CO emission from discs around isolated HAeBe and Vega-excess stars
W. R. F. Dent, J. S. Greaves, I. M. Coulson
We describe results from a survey for J=3-2 12CO emission from visible stars with an infrared excess. The line is clearly detected in 21 objects, with molecular gas (>10^-3 Jupiter…
Sub-mm observations and modelling of Vega type stars
I. Sheret, W. R. F. Dent, M. C. Wyatt
We present new sub-mm observations and modelling of Vega excess stars, using realistic dust grain models. For resolved disks, we find that different objects require very different…
A search for H2 around pre-main-sequence stars
I. Sheret, S. K. Ramsay Howat, W. R. F. Dent
We present the results of a search for pure rotational molecular hydrogen emission from two pre-main-sequence stars, AB Aur and CQ Tau. Observations were made using MICHELLE, the m…
