Star formation in Perseus
J. Hatchell, J. S. Richer, G. A. Fuller +3
We present a complete survey of current star formation in the Perseus molecular cloud, made at 850 and 450 micron with SCUBA at the JCMT. Covering 3 deg^2, this submillimetre conti…
The Effect of Diffusion on Pulsations of Stars on the Upper Main Sequence. delta Scuti and Metallic A Stars
S. Turcotte, J. Richer, G. Michaud +1
Recent dramatic improvements in the modeling of abundance evolution due to diffusion in A stars have been achieved with the help of monochromatic opacity tables from the OPAL group…
Detection of polarized mm and submm emission from SgrA*
D. K. Aitken, J. S. Greaves, A. Chrysostomou +4
We report the detection of linear polarization from SgrA* at 750, 850, 1350 and 2000 microns which confirms the contribution of synchrotron radiation. From the lack of polarization…
Molecular Outflows from Young Stellar Objects
John Richer, Debra Shepherd, Sylvie Cabrit +2
We review some aspects of the bipolar molecular outflow phenomenon. In particular, we compare the morphological properties, energetics and velocity structures of outflows from high…
