Planned visits 2 & 3 (same), based on not using G140L and adding in G160M and G185M (with some gaps in wavelength coverage). Fixed order of FP-POS in visit 3 ----- Attempting Submission 11 (Mon Nov 08 00:41:25 GMT 2010) ----- ----- Attempting Submission 12 (Mon Nov 08 23:33:53 GMT 2010) ----- ----- Attempting Submission 13 (Tue Nov 09 18:38:03 GMT 2010) ----- Usual errors (to ignore) and visit 2 $ 3 are identical using new grating settings. Taming the Invisible Monster with COS: Eclipse Spectroscopy of Epsilon Aurigae We request three single orbit COS observations of the enigmatic binary epsilon Aurigae. This 27-year binary will be in total eclipse during all of 2010 and into spring 2011. COS observations are needed in order to (1) confirm, via higher S/N UV spectroscopy, the FUSE observation that a B5V star lurks inside the eclipse-causing dust disk, (2) obtain temperature and density diagnostics of the line of sight columns during eclipse for inclusion in the ongoing, panchromatic studies of this rare event, and (3) allow, in coordination with Spitzer Space Telescope observations, a detailed view of the "invisible" large eclipsing dust disk surrounding the B star. Only COS has the full UV wavelength coverage to sample two of the three components in this binary (the F and B stars) with the SNR to accomplish our scientific goals.
We wish to use the three orbits as follows: 1) One in Sept 2010 2) Two in Dec 2010 3) Three in April 2010 HOT STARS 12 false 0.0 0.0 false false false false false false AVAILABLE STAR F3-F9 This object was generated by the targetselector and retrieved from the SIMBAD database.
