Title: Speckle Interferometry and Photometry of Binary Stars

Abstract: Binary orbits, when combined with parallaxes, yield dynamical masses, while photometry of the components restrains astrophysical models. Both are vital to understanding stellar evolution. Speckle interferometry, which is telescope resolution limited as opposed to seeing limited, allows observation of close, short-period binaries. We will use our EMCCD based speckle camera to observe some 500 binaries in the other half of the sky, complimenting (and slightly overlapping) our 2013B-0064 run on the same telescope with the same camera. We will confirm Hipparcos/Tycho double star discoveries as candidates for new binaries, classify new pairs by determining if their motion is curved (binary) or linear (optical double), add high-accuracy speckle observations that will allow the first determination of orbits, refine existing orbits by extending orbital coverage with speckle observations, and obtain precise photometry of binary components to link photometric with dynamical masses. This run will, again, employ a number of graduate and undergraduate student researchers as full research partners.
