SBE 1 Aa,Ab: Herschel 36 is a young massive system located at 1.3kpc in the
Hourglass high-mass star-forming region in the central part of the M8
nebula. The Ab component is comprised of two stars, spectral types O9V
and B0.5V, in a close orbit with period 1.54d. The Aa component is of
type O9.5V, and is the most luminous star of the system, dominating
its ionizing flux. Aa and Ab are in an orbit with estimated period
500d and projected semi-major axis 3.5mas. The minimum spectrosopic
predicted mass of the Aa+Ab1+Ab2 system is 45,2 Msun. Arias et al.
(2010, ApJ 710, L30) label the components A, B1, and B2 in their
spectroscopic study of the system. SBe2014
