The Spectroscopic Orbit of σ PISCIUM.
Abstract
Observations of the spectroscopic binary, ~ Piscium, with the Mills 3-prism spectroscope of the Lick Observatory lead to a period of 81.12 days. The spectra of both cOmponents are visible for a few days near one node but are blended during the rest of the period. Thirty-two observations near the node result in an orbit of unusually high eccentricity, e = 0.898
