HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT # 4145 PERIOD COVERED: UT June 28, 2006 (DOY 179) OBSERVATIONS SCHEDULED FGS 10612 Binary Stars in Cyg OB2: Relics of Massive Star Formation in a Super-Star Cluster We propose to make a high angular resolution SNAP survey of the massive stars in the nearby, super-star cluster Cyg OB2. We will use FGS1r TRANS mode observations to search for astrometric companions in the separation range of 0.01 to 1.00 arcsec and in the magnitud ...Continue Reading

HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT # 4144 PERIOD COVERED: UT June 27, 2006 (DOY 178) OBSERVATIONS SCHEDULED WFPC2 10551 Gamma-Ray Bursts from Start to Finish: A Legacy Approach The progenitors of long-duration GRBs are now known to be massive stars. This result lends credence to the collapsar model, where a rotating massive star ends its life leaving a black hole or a highly magnetized neutron star, and confirms its essential aspects. The focus of attention now ...Continue Reading
