Orbits of Low Mass Binary Stars in the Taurus Star-forming Region
Abstract
We present new astrometry and orbital solutions for a set of binary stars in the Taurus star-forming region. These binaries, some of which have been monitored for over two decades, were observed by our team using speckle interferometry and adaptive optics at Keck Observatory between 1997 - 2015. We combine our new data with astrometric points from the literature in order to fit orbits to those binaries with sufficient measurements. We will present new and/or updated mass estimates for these binaries, which are aided by new parallax estimates from Gaia. Our masses will be compared to predictions from theoretical evolutionary models, with a focus on the M-type binaries that have the fewest empirical constraints at the age of Taurus. Our results will aid in understanding the early evolution of low mass stars
