V1073 Cygni: A New Light Curve and Analysis
A new CCD light curve of the A-type W UMa star V1073 Cygni has beenobtained, and the differential-corrections method of Wilson and Devinneywas used to compute a new set of system parameters. The same analysishas been applied to the other photometric light curves in theliterature, including the Hipparcos light curve. A new ephemeris isdetermined for the times of primary minimum. V1073 Cygni probably hasinitially formed as a detached system and evolved into contact.
| A photometric study of the eclipsing binary V 1073 CYGNI
Photoelectric observations of the eclipsing binary V 1073 Cyg have beencarried out in B and V colors at the Ege University Observatory. Thelight curves were analyzed with the Wilson-Devinney approach. A periodstudy reveals that the orbital period of the system is decreasing at therate of (3.21 +/- 0.17) second per century.
| Radial-velocity measurements. III - Ground observations accompanying the HIPPARCOS satellite observation program: Measurements of the radial velocities of 391 stars in 12 fields
The radial velocities of 391 stars, obtained with the Fehrenbachobjective prism associated to the Schmidt telescope of the Observatoirede Haute-Provence are presented. These stars belong to fields speciallychosen for containing several Hipparcos input catalog star members. Eachfield is presented independently. The list includes HD and BDidentifiers when available, 1950 coordinates, spectral type, and B and Vmagnitudes as they appear in the CSI catalog, the radial velocity, theprobable error, the number of independent measurements and commentariessuch as known radial velocity and their origin.
| The S201 far-ultraviolet imaging survey. II - A field in Cygnus
Far-ultraviolet imagery of a region in Cygnus, a 20 deg diameter fieldcentered near (1950) R. A. 21 h 31.2 m decl. +37 deg 25 arcmin, wasobtained by the S201 far-ultraviolet camera during the Apollo 16mission. In a 10 minute exposure covering the 1250-1600 A wavelengthrange (effective wavelength 1400 A), 730 star images can be detected,corresponding to a limiting ultraviolet magnitude of about m (1400) =10. Assuming nominal interstellar extinction values in this region nearthe galactic plane, this result corresponds to the detection of A0 Vstars to a distance of 300 pc and of B0 V stars to 1500 pc.Uncertainties in spectral classification and interstellar extinction forindividual objects are probably more significant than calibration ormeasurement errors. Most of the objects detected are identified withstars in the Smithsonian Astrophysical Observatory Star Catalog (1966),or the Catalog of Stellar Identifications (1979) or both, but 87 objectsremain unidentified (or are identified with late-type stars).
