... Line radiative transfer in C 18 O, HCO + , and CS lines is considered in a spherically symmetric chemo-dynamical model of a starless core, evolution of which is driven by the ambipolar diffusion. Theoretical line profiles are compared to observational data on the well-known L1544 core, which is one of possible candidates for collapsing protostellar clouds. ... Comparison between modelled and observed spectra suggests that L1544 has flattened structure and is observed at some inclination. ...

... part 2 | ... Part 1 . The new concept of formation and development of the Solar system. ... Thus, the initial pulse of the rotation of a protosolar cloud of the solar system was determined as a result of the diversion of a part of the moment of the rotational pulse of the Galaxy. ... Besides this new approach to the pre-solar system as a system of the destroyed vortex structure, we can understand now a number of other peculiarities of the Solar system's structure. ...

... In less then one day "Mir" station will finish its flight. ... Besides, the operability of motion control systems will be tested to ensure further dynamic operation at the final stage of "Mir" complex. ... The final third burn is given in daily orbit 2 using the "ProgressM1-5" 8 control engines and its main engine with the trust of 300 rg/s. Thus, to peform deorbit maneuver the OC"MIr" real-time tested manuevers involving control engines and their combination with the main engine are used. ...

... The department was founded in late sixties by Prof. D.Ya.Martynov, who for many years was also the director of Sternberg Astronomical Institute. At present time, the head of the department is Prof. A.M.Cherepashchuk, a pupil of D.Ya.Martynov and his successor as the director of SAI. Since Prof. Martynov, the scientific activity of the department was primarily related to binary stars. ... The department consists of 15 members most of which have Ph.D. in Astrophysics. ...

... 1) The MS lower envelopes for groups of stars with different metallicities turn out to be coincident. ... 4) The conformation of the kinematics of stars within narrow ranges ob b-y with the ages derived from isohrones reveals that, at Z < Z , the isohrone ages seem to be increasingly overestimated with growing b-y . ... At a given metallicity, they have a much narrower MS and the locus of their MS lower envelope seems to be brighter for the metal-rich group of stars. ...
