The Old Disk Population Star HR 1071 McAlister, Harold A. ; Hartkopf, William I. ; Mason, Brian D. Abstract HR 1071 (F7V, V = +6.36) is an old disk population star of low rotational velocity, moderately low metallicity, and extremely low Li abundance. The star was not recognized as being a binary system until its discovery as such from speckle observations obtained in late 1985. Rapid orbital motion has now permitted us to make a preliminary orbit determination from which we find an orbital period of 13.8 yr. Combining the elements of the apparent orbit with an estimation of the distance to the system and with a qualitative determination of the magnitude difference, we show that the system is a likely candidate for detection as a double-lined spectroscopic binary. This provides an excellent opportunity to directly determine masses and luminosities for the components of this intersting system. Finally, we discuss the implications of the duplicity of HR 1071 and other stars upon lithium abundance.
