Description:
One-thousand one-hundred ninety-seven observations of 730 binary star
systems, observed by means of speckle interferometry with the 4m
telescope on Kitt Peak, are presented. Included in these binary stars
are new interferometric companions to five visual binaries. These
measurements, made mostly during the period 1991 to 1993, comprise the
11th installment of results stemming from our speckle program at the
4m class telescopes on Kitt Peak, Cerro Tololo, and Mauna Kea.

Notes (1): Notes on individual stars:
02366+1226 = HR 763 = McA 7: These three measurements of 31 Ari were based
on reprocessing of archival video data. A combined spectroscopic/speckle
orbital analysis of this very close system is now in progress, in
collaboration with Frank Fekel.
04404+1631 = vB 185 = CHARA 154: This confirms the discovery observation of
this Hyades binary, made in 1991 (Mason et al. 1993a).
05271+1758 = ADS 4038 = McA 19 Aa: All archival data for this system were
reprocessed, resulting in four new unresolved measures as well as the
new 1991 measurement. In addition, new rho and theta values have been
determined for the observations originally published from 1986.9-1988.3
(McAlister et al. 1989), 1988.7-1989.2 (McAlister et al. 1990), and
1990.3-1990.8 (Hartkopf et al. 1992). The date of the 1988.2518
measurement was incorrectly given as 1988.2490 in McAlister et al. (1989).
Orbital analysis of this system is in progress; a preliminary orbit gives a
period of ~15.3 years and a semi-major axis of 0".080.
06017+2224 = HR 2116 = CHARA 161: This confirms the discovery observation,
made in 1988 (McAlister et al. 1993).
06212+2932 = HR 2272 = CHARA 165: This confirms the discovery observation,
made in 1988 (McAlister et al. 1993).
07277+2127 = ADS 6089 = McA 30 Aa: A combined spectroscopic/speckle orbit of
this system has been undertaken in collaboration with Frank Fekel.
08095+3213 = ADS 6623 = CHARA 190 Aa: This is a new component to the wide
(2".8) pair STF 1187, discovered by Struve in 1829.
10453+3831 = ADS 7915 = Ho 532 AB and CHARA 191 Aa: The Aa pair appears to be
a new component to the 0".7 pair Ho 532. This new component was actually
first resolved back in 1983 (McAlister et al. 1987) but it was believed at
the time that the measurement was of the known pair (the wide component laid
outside the processor "window" of our old autocorrelator). Reprocessing
of our archival video data allowed us to resolve both components in
the 1983 and 1984 data sets, although both early measurements of
the Aa component are quite weak.
11150+3735 = ADS 8102 = CHARA 192 Aa: This is a new component to the 0".6
pair STT 232, discovered by Otto Struve in 1843. Reprocessing of archival
data (whose 1987 and 1988 measurements for the wide pair were originally
published in McAlister et al. 1989) has allowed us to confirm this discovery
and also to note that the system appears to be accelerating toward
periastron.
11182+3132 = ADS 8119 = STF 1523 AB: An orbital analysis of Xi UMa,
including both the AB pair, the astrometric companion, and the
newly-discovered Bc companion, is now in preparation by Mason et al.
13175-0041 = HR 5014 = Fin 350: Orbital analysis of this system is in
progress. In the process we have been able to resolve the uncertainty between
a possible short-period/high-eccentricity orbit and a
long-period/low-eccentricity one.
13197+4747 = ADS 8862 = CHARA 193 Aa: This is a new component to the
1".5 49-year period pair of M2 dwarfs Hu 644. This is the only one of the
current crop of new interferometric binaries which has not yet been
confirmed.
15245+3723 = ADS 9626 = CHARA 181 Aa: This confirms the discovery observation
of this pair, made in 1988 (McAlister et al. 1993).
17215+2845 = HR 6466 = CHARA 194 Aa: This is a new close companion to the
0".7 pair Kui 80. The primary of this system is listed in the preliminary
version of the BSC5 (Hoffleit & Warren 1992) as a G0III spectroscopic binary.
17217+3958 = HR 6469 = McA 47: A new combined spectroscopic/interferometric
orbital solution has now been completed and submitted to AJ
(Scarfe et al. 1994).
17572+2400 = HR 6697 = McA 50: All our CCD speckle data for this close system
have been reprocessed and examined. In addition, we have listed 7 negative
measures dating from observations made at the KPNO 2.1-m in the 1970's. A
combined spectroscopic/interferometric orbit is now in preparation
(McAlister et al. 1994).
17584+0427 = +04 3562 = Kui 84: A measurement published by McAlister et al.
(1987) dating from 1985.4872 was misidentified as being of Kui 84; the
measurement actually was of Kui 89 (WDS 18594-1250). In addition, an
observation of Kui 84 dating from 1988.6655 (theta=270.6deg, rho=0".134)
was published by McAlister et al. (1990). These data have been reprocessed,
and we now believe this measurement was spurious.
18594-1250 = HR 7166 = Kui 89: This measurement was incorrectly attributed to
Kui 84 (WDS 17584+0427) by McAlister et al. (1987).
20158+2749 = HR 7744 = CHARA 94 Aa: These two observations confirm the
discovery measurement of this close component, made in 1985 (McAlister et al.
1987), and indicate considerable motion during this interval.
20462+3358 = ADS 14274 = CHARA 100 Aa: This appears to have finally confirmed
the discovery observation of this component, made in 1983 (McAlister et al.
1987). A number of unresolved observations of this very close system, dating
from 1979 to 1981, were published by Hartkopf & McAlister (1984).
20474+3629 = ADS 14296 = McA 63 Aa: Orbital analysis of Lambda Cyg is in
preparation; a preliminary orbit gives a period of 11.8 years and a
semi-major axis of 0".049.
21145+1001 = ADS 14773 = STT 535 AB: A combined spectroscopic/speckle orbit of
this system has been undertaken in collaboration with Frank Fekel.
23460+4625 = HR 9003 = McA 75 Aac: With this measurement we appear to have
finally confirmed the discovery observation of this component, made in 1981!
(McAlister et al. 1984).
