Differential BVR light curves of DK Cyg
New CCD photometry is presented for the hot overcontact binary DK Cyg together with reasonable explanations for the light and period variations. Historical light and velocity... -
UBV and proper motions of Palomar 13
We present a proper-motion, CCD photometric study of stars in the distant halo globular cluster Palomar 13. The absolute proper motion of Pal 13 with respect to the background... -
UBV photometry of LMC OB associations
Using ultraviolet photometry from the Ultraviolet Imaging Telescope (UIT) combined with photometry and spectroscopy from three ground-based optical data sets we have analyzed... -
BVI photometry of Variables in M33
The DIRECT project aims to determine direct distances to two important galaxies in the cosmological distance ladder - M31 and M33 - using detached eclipsing binaries (DEBs) and... -
BVI photometry of central part of M33
The DIRECT project aims to determine direct distances to two important galaxies in the cosmological distance ladder - M31 and M33 - using detached eclipsing binaries (DEBs) and... -
BVIJH photometry of M82
We present high-resolution HST imaging in the optical (WFPC2) and near-infrared (NICMOS) of a disk region 1kpc northeast of the starburst core in the nearby galaxy M82. Cone... -
BV photometry in NGC 5986
We have obtained new CCD BV photometry of the little-studied southern Galactic globular cluster NGC 5986, including light curves of five of its RR Lyrae variables. The cluster's... -
UBVR photometry of NGC 6712 with VLT
We present extensive UBVR photometry of the Galactic globular cluster (GGC) NGC 6712 obtained with the ESO Very Large Telescope (VLT) which reaches down to 2 mag below the... -
UBVI photometry of NGC 3201
This paper aims at further studying one of the nearby Galactic globular clusters (GCs), NGC 3201. It is known to experience notable irregular variability of reddening across its... -
Photometry of candidate members of NGC6611
We present the list of candidate members of the young open cluster NGC 6611, selected in a field of view of 33'x34' by the X-rays emission and excesses in infrared bands. X-ray... -
BV photometry of RT Lac
Contemporaneous spectroscopic and photometric BV observations of the RS CVn type eclipsing binary RT Lacertae were performed in summer 2000. The photometric observations were... -
BVI photometry of two open clusters
We present the results of CCD BVI Johnson-Cousins photometry down to V~19mag in the regions of the unstudied stellar groups Pismis 23 and BH 222, both projected close to the... -
UBV photometry of V832 Cyg
An analysis of numerous homogenized UBV photoelectric observations and red spectra of the Be star from several observatories is presented. -
UBVI photometry of NGC 133 and NGC 1348
We present CCD UBVI observations obtained in the field of the previously unstudied northern open clusters NGC 133 and NGC 1348. We argue that NGC 133 is a heavily contaminated... -
UBV photometry of V899 Her
The data file (v899her.dat) includes photometric observations of the eclipsing binary system V899 Herculis. The observations were carried out at the Ankara University... -
UBV(RI)c photometry of 7 symbiotic stars
The Asiago photographic archive has been searched for plates containing the symbiotic stars Hen 2-468, QW Sge, LT Del, V407 Cyg, K 3-9, V335 Vul, FG Ser and Draco C-1. A total... -
BVRIJHK photometry of 27 post-AGB candidates
BVRIJHK photometric observations are presented for 27 post-AGB candidates. Almost all objects show a double peaked spatial energy distribution (SED) curve in the optical to... -
UBVI photometry of NGC 7036 and NGC 7772
We present CCD UBVI observations obtained in the field of the two previously unstudied dissolving open cluster candidates NGC 7036 and NGC 7772. Our analysis suggests that both...
