Sagittarius Dwarf Galaxy VI photometry
We present V,I deep CCD photometry for three fields of the dwarf galaxy in Sagittarius (Sgr), located at l=5.6{deg}, b=-14.1{deg}. One of the fields is centered on the globular... -
AN Lyn light maxima
New uvby data collected of AN Lyn together with the reanalysis of old data establish that this star is a multiperiodic pulsator. Three independent frequencies ({nu}1=10.1756,... -
Companions to M dwarfs within 5pc
The paper contains four tables which summarise the duplicity status of the 34 M dwarf primaries within 5.0pc. Table 1 gives the basic data for the sample: designation,... -
NGC 5548 continuum light curve
The variations of the [OIII]{lambda}5007 line profile in NGC 5548 are examine d from CCD spectra obtained at the Ohio State University and Crimean Astrophysic al Observatory in... -
Radial velocities & photometry of classical Cepheids
Radial velocities and distances have been measured for a sample of 48 remote classical Cepheids located in the outer disc of the Galaxy (118deg<l<274deg). The distances... -
Revised photometry of SNIa
Re-calibrated B magnitudes and (B-V) colors for the stars of the local sequences used at Asiago in the seventies as reference for the SN photometry are given in table3. For... -
Photometry of the Tuc dwarf galaxy
We present V and I CCD photometry for ~360 stars in the recently discovered dwarf galaxy Tucana. The large field investigated and the accurate photometric calibration make our... -
BVI photometry of two Orion galaxies
Two relatively faint (B=15.7 and B=18.4mag, respectively), low velocity (+276 and +322km/s) galaxies were imaged with a CCD in the B, V, I bands at the prime focus of the 6m... -
Tucana dwarf galaxy VI photometry
We present deep CCD photometry for the dwarf galaxy in Tucana (l=323, b=-47.4). The data indicate that the galaxy is dominated by an intermediate/old stellar population with... -
Optical brightness of 3 ROSAT Seyfert galaxies
The printed version of this paper describes the X-ray and optical properties of four new active galaxies discovered in the ROSAT All-Sky Survey. While one object (RX... -
Liller 1
We carried out VRI and Gunn z observations of the obscured globular cluster Liller 1. The cluster is so reddened (A_V_=~9.0) that it is at the detection limit in V. The RGB in I... -
Photometry and radial velocities of 16 Lac
Photometric and spectroscopic observations of the {beta} Cephei star 16 Lacertae obtained in 1983 and 1984 are presented and analysed. Using all the published maxima we have... -
NOT GL survey of multiply imaged quasars
A gravitational lens (GL)-search program, initiated in 1990 at the Nordic Optcal Telescope (NOT), has revealed several possible GL-candidates among a sample of 168 quasars... -
Pleiades field Membership probabilities
A catalogue of proper motions and photographic B,V magnitudes for stars up to B=19 mag within a region centered near Alcyone is presented. The catalogue is based on MAMA... -
Main sequence of NGC 6171
Deep J, K IR-array photometry for individual Main Sequence stars in NGC 6171 reaching K~18, about two magnitudes below the turnoff, is presented. The observations were made... -
E+A galaxies in Cl0939+472
We present results of a study of E+A galaxies in the cluster Cl0939+472 (z=0.41). We have used a series of narrow-band filters (FWHM~=90-200A) covering the range from 3800 to... -
Low Surface Brightness galaxies in Coma
Using the prime focus of the 6-meter telescope, we have searched for low surface brightness dwarf galaxies in two regions in the Coma cluster: one in the center of the cluster... -
3C 295 BRri photometry
We observed the cluster Cl 1409+524 (z=0.46) with an imaging Fabry-Perot interferometer. A sequence of Fabry-Perot images (FWHM=1.0-1.3nm) was used to search for redshifted... -
