GAA 2	AW Per. This Cepheid is an SB with an orbital period of ~40 yr. First
	discovered by Miller & Preston (1964 PASP 76, 47), it took several
	years to derive the first orbit from radial velocity data (Evans 1989
	AJ 97, 1737). It is likely that this companion is itself a binary, as
	argued by Evans and by Evans et al. (2000 AJ 120, 407), because the
	magnitude difference between the Cepheid and its companion is not
	consistent with equal masses and predictions from evolutionary tracks.
	Unfortunately, Gallenne et al. (2015) note they did not have enough
	angular resolution and sensitivity to detect this third companion. The
	properties of the brightest companion were studied based on IUE
	spectra by Evans (1994 ApJ 436, 273; 1995 ApJ 445, 393), who found its
	spectral type to be B8.3V. This is in agreement with their detection
	with a flux ratio f = 1.22 +/- 0.30%, i.e., a spectral type in the
	range B6-B9V (using d = 853 pc from a P-L relation and K = 4.63 mag
	for the Cepheid). They estimate the companion mH = 9.6 +/- 0.3 mag
	(using for the Cepheid at theirgiven phase mH = 4.84 +/- 0.01 mag from
	Monson & Pierce (2011 ApJS 193, 12). Massa & Evans (2008 MNRAS 383,
	139) also determined the angular separation of the component for
	another epoch, which will allow an estimate all the orbital elements,
	(see also Gallenne et al. 2013 EAS Pub. Ser. 64, 197). Gallenne et al.
	(2015) derived a maximum sensitivity limit at 3sigma of 0.62%, i.e.,
	dmH> 5.5 mag, so can therefore exclude any additional components with
	a spectral type earlier than B9V.	GaA2015
	Spectroscopic binary orbit with P = 13954d determined.	Grf2016c
