We present CCD photometric observations of 23 main-belt asteroids, of which 8 have never been observed before; thus, the data of these objects are the first in...

CCD photometry of 18 Jupiter family comets, observed at medium and large heliocentric distances, was carried out between April 1990 and July 1995. This is part...

We present CCD observations of the galactic globular cluster M15, in the B and V filters. The cluster was reasonably covered, except in its northern region...

The authors present CCD UBV photometry of 142 resolved stars in the Local Group dwarf irregular galaxy GR 8. Its distance modulus has been found to be 25.0. The...

CCD UBV photometry of 2279 stars in Sextans A is presented. Differences with the photometric scales of Sandage and Carlson (1985) and Hoessel et al. (1983) are...

CCD photometry of resolved dwarf irregular galaxies was obtained with the 4-m Cerro Tololo Interamerican Observatory telescope in February 1985. BV data from 77...

CCD photometry for stars in three fields centered on the old open cluster NGC 188 is presented, with the aim of investigating the HR diagram distribution of...

We report the results of CCD V and R photometry of the RR Lyrae stars in M2. The periodicities of most variables are revised and new ephemerides are calculated...

CCD photometry of the M87 jet in the Thuan-Gunn r and g filters is presented. Accurate elliptical models of the underlying stellar emission were subtracted from...
