V light curve of SDSS J080434.20+510349.2 (Zharikov+, 2008)
We observed a new cataclysmic variable (CV) SDSS J080434.20+510349.2 to study the origin of long-term variability found in its light curve. Multi-longitude...
We present differential CCD photometry for the high-amplitude delta Scuti star V567 Ophiuchi obtained in the Johnson V-band. It was observed on 15 nights in two...
V-R diagram for spiral galaxies - New insights into the Hubble sequence
The present examination of the relation between the global parameters of spiral galaxies and their morphological type represents rotational velocity V at 25 mag...
The relation among V-type asteroids in the Main Belt, the large basaltic asteroid (4) Vesta and the HED meteorites is a long standing issue. To better...
Current theories predict that very young giant planets have large radii and very low densities before they slowly contract to reach their final size after...
