HUBBLE SPACE TELESCOPE - Continuing to collect World Class Science DAILY REPORT       # 4581 PERIOD COVERED: UT April 02, 2008 (DOY 093) OBSERVATIONS SCHEDULED NIC 11495 The first direct detection of an extrasolar planetary stratosphere? We request NICMOS grism spectroscopy to observe the transit of WASP-3b. This newly discovered planet is the hottest nearby planet discovered so far. The atmosphere is predicted to be so hot that TiO and VO remain in the gas phase, creating a hot, s ...Continue Reading

Here we propose to discover binaries ...Continue Reading

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

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
