HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT       # 4577 PERIOD COVERED: UT March 27, 2008 (DOY 087) OBSERVATIONS SCHEDULED FGS 11210 The Architecture of Exoplanetary Systems Are all planetary systems coplanar? Concordance cosmogony makes that prediction. It is, however, a prediction of extrasolar planetary system architecture as yet untested by direct observation for main sequence stars other than the Sun. To provide such a test, we propose to c ...Continue Reading

HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT    # 4576 PERIOD COVERED: UT March 26, 2008 (DOY 086) OBSERVATIONS SCHEDULED FGS 11211 An Astrometric Calibration of Population II Distance Indicators In 2002 HST produced a highly precise parallax for RR Lyrae. That measurement resulted in an absolute magnitude, M{V}= 0.61+/-0.11, a useful result, judged by the over ten refereed citations each year since. It is, however, unsatisfactory to have the direct, parallax-b ...Continue Reading

The main goal of this proposal is to measure the FUV continuum, Ly-a emission line flux, and their evolution to {1} quantify and interpret Type IIn SN transient event det ...Continue Reading
