Astro Space Center of P.N.Lebedev Physical Institute , Profsoyuznaya 84/32, Moscow 117810, Russia . We argue that the contribution of cosmic gravitational waves into the large-scale CMBR anisotropy can exceed for a broad class of the inflationary models with effective -term producing the standard local spectrum of primordial cosmological perturbations. ...

... Study of Mg-Fe-silicate glasses of variable composition. ... With the new data, the astrophysical discussion started in Paper I was continued and focussed on the comparison of the olivine glass data with IRAS LRS spectra of O-rich circumstellar envelopes around Mira stars. ... The new olivine glasses point to the interesting consequence that the temperature for silicate dust grains at the inner edge of circumstellar envelopes must be considerably higher than the values often given in the literature....

... We have used a coupled dynamical and chemical model to examine the chemical changes caused by the passage of a density wave propagating into the protostellar cloud. ... The chemical coupling between gas and dust causes locally increased number densities of active ra dicals, such as C, N, O, NH, and OH, and hydrogen saturated molecules CH 4 , NH 3 and H 2 O. We show that chemical evolution in the post-wave gas can account for the observed abundance of water and NH 3 observed in interstellar clouds. ...

Dogiel (P.N.Lebedev Institute of Physics) . ... It was concluded also from these investigations that it is problematic to produce emitting electrons from a background plasma by stochastic (Fermi) acceleration because the energy supplied by external sources in the form of Fermi acceleration is quickly absorbed by background plasma. ...

... Programme . ... Abstract: Active galactic nuclei such as Centaurus A have been proposed as sources of ultra-high energy (UHE) cosmic rays and neutrinos. ... The most recent such experiment was with the Parkes radio telescope in March 2009, and employed a new scheme to discriminate against impulsive radio-frequency interference. It was optimised for sensitivity to any UHE neutrino flux from Centaurus A. The non-detection from this experiment allows us to place an upper limit on this flux. go back . ...

Influence of Asteroids and Trans-Neptunian Objects on the Motion of Major Planets and Masses of the Asteroid Main Belt and the TNO Ring . ... Perturbations from asteroids and Trans-Neptunian Objects (TNOs) produce a significant effect on the orbits of planets and should be taken into account when high-accuracy planetary ephemerides are constructed. On the other hand, from an analysis of motion of the major planets some physical parameters of the asteroids and TNOs may be obtained. ...

... We construct a composite quasar spectrum from 149 HST FOS spectra of 80 quasars with mean redshift . ... The continuum longward of 1000? can be modeled as a power law with . ... The break in the power--law index is a feature expected in Comptonized accretion--disk spectra. ... The spectral features in the sub--Ly region of AGN spectra provide critical insights into the physical processes around the central engine, and they become accessible to IUE and HST at intermediate redshift. ...

Close binary systems of the RS CVn and Algol type are characterized by a highly variable radio emission, from typical flux densities of a few mJy during low-activity (quiescent) periods, up to 1 Jy during strong flares. The origin of this radio emission is attributed to the gyrosynchrotron mechanism. Several observations of these stars have shown an evolution of the radio spectrum during both the rising and decay phases of flares. ...
