Abstract:
We present spectroscopic and photometric observations of the eclipsing
system V1061 Cyg (P=2.35days). A third star is visible in the
spectrum, and the system is a hierarchical triple.
Description:
V1061 Cyg was observed at the CfA with an echelle spectrograph
on the 1.5m Wyeth reflector at the Oak Ridge Observatory (eastern
Massachusetts) and occasionally also with a nearly identical
instrument on the 1.5m Tillinghast reflector at the F. L. Whipple
Observatory (Arizona). Relative photometric observations of V1061 Cyg
were obtained at two different facilities. Measurements in the V band
were made with the 0.26m URSA robotic telescope at Kimpel Observatory
on the campus of the University of Arkansas at Fayetteville. A total
of 6914 observations were collected between 2001 March and 2004
October. Observations were also made with the 0.4m f/11 Ealing
Cassegrain reflector at Gettysburg College Observatory, in Gettysburg
(Pennsylvania), between 2002 September and 2003 September.
