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. ...

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. ...

... 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. ...

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. ...

... Obs., 1974, v.49, p.80-85. The sixty five radial velocity measurements of Cep C (blue visual companion of Cep A) have been obtained. The evidences are give that Cep C is spectral binary. The most probable periods of system are: 0 d ,89986 and 0 d ,46458 . In both cases the -velocity of Cep C is in good agreement with mean velocity of Cep A. It is a strong argument on their physical connection. The secondary component of Cep C may have very low mass (near 0.1 solar mass or less). ...

Meteor showers on Earth from sungrazing comets . ... The perihelion passage of comet C/2012 S1 (ISON) at the end of this year (on 2013 November 28) is an eagerly awaited event. ... Our calculations show that although the orbital elements of this comet are much more favourable than for most sungrazers to have its descending node near the Earth's orbit, even ejection velocities as high as 1 km s-1 do not induce sufficient nodal dispersion to bring meteoroids to Earth intersection during present times. ...

ABSTRACT: Both previous radiomessages for aliens, Arecibo 1974 and Evpatoria 1999 (see http://ebe.allwebco.com/Science for details) were the logical ones and represented the binary stream of FM information, which should be arranged into two-dimensional forms to perceive by eye-like sense-organ. ...

Despite the wide spread use of the terms MTF, CTF, limiting resolution, minimum resolvable target, and contrast to describe CCD image system quality, the terms are often misused and their relations are little understood. ... The modulation transfer function (MTF) is a Fourier transform of the line spread function i.e. its equivalent as an integral sum of sine waves taken over the whole range of spatial frequencies. MTF by its Fourier nature can only be used to operate on sinusoidal frequencies. ...
