1. Solar System Research
... This recently reintroduced area of research at the Observatory continues a tradition established at the Observatory by E.J. Opik , focusing on problems involving the origin and evolution of comets , their dynamical transfer from the Oort cloud and other reservoirs into short-period orbits , the interrelationship between comets and asteroids (particularly objects in Earth-crossing ... The first concerns the origin and evolution of the Oort cloud in the Galaxy. ...

... The observed isotropy on the sky and non-uniform spatial distribution of gamma-ray bursts (GRB) revealed by the BATSE device onboard the Compton Gamma-Ray Observatory (e.g. Meegan et al. , 1992)[ 138 ] lend support to the idea of a cosmological origin of GRB (Prilutski and Usov, 1975;[ 165 ] Usov and Chibisov, 1975)[ 199 ] for which the best candidates could be merging binary NS+NS or NS+BH at high redshifts (z 1 -2), (Blinnikov et al. ...

... The analysis shows, that asteroid rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

4. A New Stable Method for Long-Time Integration in an N-Body Problem
Next: Imaging by an Optimizing Method . ... A big advantage of this numerical integrator is its stability: the error in the semi-major axis and the eccentricity depends only on the step size and does not grow with an increasing number of time steps. ... As the integration time increases, the numerical results become more contaminated by various errors. ... A new symplectic integrator produces no secular truncation errors in the actions of a Hamiltonian system. ...

5. Informational system "Evolution of RG"
The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

Overall, there are about 100 rotation periods known for PMS stars. ... Furthermore, the stars with periods near 8 days also tend to have infrared excesses which can be interpreted as arising from disks. ... In the first interpretation, the gap occurs because locking mechanism holds stars at a eight day rotation period. ...

Morphology and Models of Faint Galaxy Counts D.C. Koo University of California Observatories/Lick Observatory University of California, Santa Cruz Most models of faint galaxy counts continue to rely on transforming observed distributions of morphology of local galaxies to estimate the distribution of K corrections. ... For example, at B ё 24, our noevolution models predict counts that are only 50% shy of the observed (Koo, Gronwall, & Bruzual 1993, ApJL, 415, L21). ...
