Spectroscopic binary orbits from photoelectric radial velocities. Paper 81: HD 177390
Abstract
The HD 177390/1 system, to which the Henry Draper Catalogue ascribes a composite spectrum (A0+G), is actually a double-lined spectroscopic binary consisting of a slightly unequal pair of metallic-lined A stars in a circular orbit whose period is very close to 8 days.
