The variations of universal times difference UT1-TAI and Earth’s rotation instantaneous pˆole coordinates (X,Y) are studied in the frequency range of 3 - 8 yr−1 as a function of the solar...
143 precise astrometric positions of seven comets were obtained with the CCD equipped Askania astrograph (13.5/160) of Belgrade Astronomical Observatory. The SBIG ST-8(1530 × 1020 pixel array) camer...
We report on BVR precise photometry of active late-type stars EK Dra and 29 Dra in the spring of 2004. The analysis suggests a reasonable t with single spot model for both cases in the season as fa...
We present the results of a search for new candidate radio su- pernova remnants (SNRs) in the nearby starburst irregular galaxies NGC 4214 and NGC 4395 using archived radio observations made with th...
太阳系外恒星行星系统的探测与研究进展。
Based on the relevant available data, the distributions of masses and apparent magnitudes of stars belonging to globular star clusters are simulated. The simulations are aimed at examining the in°ue...

The current paper is aimed at getting more insight on three main points concerning large-scale astrophysical systems, namely: (i) formulation of ten- sor virial equations from the standpoint of anal...
Assuming that the disc of our Galaxy, the Milky Way, obeys the classical exponential law, that it is maximal and the Sun is rather far from the maximum of its circular velocity, one ¯nds that, ...
We reconsider the basic properties of the classical minihalo model of Rees and Milgrom in light of the new work, both observational (on "dark galax- ies" and masses of baryonic haloes) and theoretic...
We present the results of new high resolution ATCA observations of SNR J0519{6926. We found that this SNR exhibits a typical "horseshoe" ap- pearance with ®={0.55§0.08 and D=28§1 pc. No polariza...
A particular case of steady state and spherical symmetry - the so- called logarithmic potential introduced as the ¯rst approximation for dark coronae of galaxies - is studied. Both time and ang...
The long-term discharge evolution of branches of rivers can potentially be derived from inactive and fossil river meanders using relations between discharge and channel width and meander dimensions....
