Abstract:
An analysis of an extensive collection of photometric and
spectroscopic observations of the little studied bright Be star V360
Lac lead to the following main conclusions:
(1) V360 Lac is a binary system consisting of a B3e primary and a F9IV
secondary which probably fills the Roche lobe and losses mass towards
the primary. Radial-velocity curves of both components were obtained.
(2) The light variations arise from superposition of variations on at
least three time scales: phase-locked orbital brightness and colour
changes with two minima; sinusoidal variation with a 322.24d period
and low-amplitude rapid changes with a possible period of 1.6738d.
(3) A tentative solution of the B and V light curves which assumes the
semi-detached configuration and presence of a disk around the primary,
combined with the orbital solution, leads to preliminary basic
physical elements of the system which are consistent with the
radiative properties of the binary components.
