HR 362 : double-line spectroscopic binary.
Abstract
Orbital elements are determined for the double-line spectroscopic binary HR 362. The elements for the primary component agree well with those determined by Christie (1933), with a revised period of 9.07530 + or - 0.00001 days, and a small but significant eccentricity of 0.040 + or - 0.007. The spectral types of the two components, as indicated by the mass ratio of 1.41 + or - 0.03, are F7 V and G7 V. The system may also exhibit partial eclipses, indicating that the minimum masses of 1.16 + or - 0.04 solar masses and 0.83 + or - 0.02 solar mass are within a few percent of the true masses.
