This study provides new arguments for the existence of local quasars, i.e. quasars in the vicinity of low redshift galaxies. Local quasars are probably ejected from respective parent galaxy. The sample includes 74 quasars in the vicinity of 8 differe

A new approach is proposed for the old problem of the planetary orbital distances in the Solar System. The solution is a simple exponential formula of the type: an= C e 2n/k . The same formula with different parameters could be used also for a large

We follow, using both optical spectroscopy and photometry, the ‘‘ textbook ’’ colliding-wind WR+O binary WR 140 through and between the periastron passages of 1993 and 2001. An extensive collection of high-quality spectra allows us to derive

In the framework of a search campaign for short-term oscillations of early-type stars we analysed recently obtained spectroscopic and photometric observations of the early A-type spectroscopic binaries 21 Her and Gem. From the radial velocities of 21

In 1999 and 2000 we obtained spectroscopic and photometric observations of the A-type binary star HD 169981. The observations were part of a campaign to search for short-term photometric and radial-velocity variations among early-type binaries. From

We describe multi-wavelength, simultaneous observations of the RS CVn star, II Pegasi, most of which were obtained during the first three weeks of September 1992. These observations were made using optical and infra-red broad-band photometry, ultravi

Spot photometry in theUBV was obtained for the flare star BY Dra during 1985-1991 at the Bulgarian National Astronomical Observatory. Light curves are presented for 1986, 1987, 1988, and 1991. There are significant variations of the amplitudes of the

Photographic photometry reveals the dwarf galaxy VIIZw009 as an outstanding object with respect to the large colour excess of its central star burst region. It seems to be a similarity to the system IC 10, which also contains at least one star burst

The ll year sunspot cycle is but one manifestation of the variability in the atmospheric activity of the Sun. For other stars Wilson (1978) demonstrated cyclic behavior in the chromospheric output as measured by variation in the strength of the Ca II
