Abstract This is a continuation of a project begun in Cycle 7 and continued up through Cycle 11. The program consists of annual or biannual WFPC2 or FGS observations of three visual binary stars that will ultimately yield fundamental astrophysical results, once their orbits and masses are determined. Our targets are the following: (1) Procyon (P = 41 yr), for which our first WFPC2 images yielded an extremely accurate angular separation of the bright F star and its much fainter white-dwarf companion. Combined with ground-based astrometry of the bright star, our observation significantly revised downward the derived masses, and brought Procyon A into excellent agreement with theoretical evolutionary tracks for the first time. With the continued monitoring proposed here, we will obtain masses to an accuracy of better than 1%, providing a testbed for theories of both Sun-like stars and white dwarfs. (2) G 107-70, a close double white dwarf (P = 19 yr) that promises to add two accurate masses to the tiny handful of white-dwarf masses that are directly known from dynamical measurements. (3) Mu Cas (P = 21 yr), a famous metal-deficient G dwarf for which accurate masses will lead to the stars' helium contents, with cosmological implications. ------------------------------------------------------------------------------------ 10112( 2) - 05/17/04 14:21 - [ 2] Observations Description ------------------------ We will obtain direct images with WFPC2 of Procyon and Mu Cas, and astrometry with FGS of G~107-70 and surrounding reference stars. Each binary will be observed once or twice per year for the next three years (and we would expect to continue to observe them through the lifetime of HST), in order to obtain very accurate masses for the stellar components. The WFPC2 filters have been chosen appropriately for each target. Unfortunately, Procyon~A is far too bright for the High Resolution Channel of ACS, (which has a 0.1~sec minimum exposure time, high sensitivity [a disadvantage for this program suitably narrow filters). Even 5th-mag Mu Cas~A would reach $\sim$2/3 of saturation in 0.1~sec, in the narrowest near-IR filter, making a switch from WFPC2 to ACS/HRC too risky. Fortunately, WFC3 will have suitable filters for use after WFPC2 is removed during Servicing Mission~4, so that the program can be continued. The FGS cannot be used for Procyon, because it is too bright, and for Mu Cas, the $\Delta$mag in the optical band is too large for FGS. The following table summarizes the program. Each observation requires just one orbit of HST time. Star delta mag sep (") P (yr) Visits/yr Instrument Procyon 9 4.7 41 1 WFPC2/F218W G 107-70 0.3 0.6 19 2 FGS/F583W Mu Cas 5 0.7 21 2 WFPC2/F953N Real Time Justification ----------------------- The observation times are weakly time-critical, since we want them spaced roughly equally in time, at about yearly intervals for Procyon and biannually for the other two targets. G 107-70 has moreover to be observed at the times of maximum parallax factor, in April and October.
