The spectroscopic binary δ Pictoris
Abstract
The first spectroscopic orbit of the early-type binary 8 Pic (revised type B o (?III)) has been derived. The period of days fits observations at Radcliffe (1963-4), Cordoba (1949-50) and Lick Southern Expedition (`914). A secondary spectrum is detected for the first time and a mass ratio of I 89 j is derived; the system is a massive one with m1 sin3 i = 0, m2 sin3 i = 0. Cousins' discovery that the star is an eclipsing binary with two minima will eventually allow individual masses to be calculated.
