Using Cepheids to determine the galactic abundance gradient I. The solar neighbourhood
S. M. Andrievsky, V. V. Kovtyukh, R. E. Luck +7
A number of studies of abundance gradients in the galactic disk have been performed in recent years. The results obtained are rather disparate: from no detectable gradient to a rat…
Using Cepheids to determine the galactic abundance gradient II. Towards the galactic center
S. M. Andrievsky, D. Bersier, V. V. Kovtyukh +4
Based on spectra obtained at the Anglo-Australian Observatory, we present a discussion of the metallicity of the galactic disc derived using Cepheids at galactocentric distances 4-…
ESO 603-G21: A strange polar-ring galaxy
V. P. Reshetnikov, M. Faundez-Abans, M. de Oliveira-Abans
We present the results of B, V, R surface photometry of ESO603-G21 - a galaxy with a possible polar ring. The morphological and photometric features of this galaxy are discussed. T…
X-ray and optical periodicities in X-ray binaries. I.A0535+26
V. Larionov, V. M. Lyuty, G. V. Zaitseva
A homogeneous set of UBV photometry (354 data points obtained between 1983 and 1998) for the Be/X-ray binary A0535+26 = V725Tau is analysed, aiming to look for possible periodic co…
Radial Velocities of Dwarf Spheroidal Galaxies in the M81 Group
M. E. Sharina, I. D. Karachentsev, A. N. Burenkov
Long-slit observations of 4 dwarf spheroidal galaxies in the M81 group are presented. We have obtained a heliocentric velocity of globular cluster candidate located near the center…
Statistics of galaxy warps in the HDF North and South
V. Reshetnikov, E. Battaner, F. Combes +1
We present a statistical study of the presence of galaxy warps in the Hubble deep fields. Among a complete sample of 45 edge-on galaxies above a diameter of 1.''3, we find 5 galaxi…
