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. ...

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. ...

Dear colleagues, we would like to remind you about Workshop on Precision Physics and Fundamental Physical Constants (FFK 2013), which will be held in St. Petersburg from October 7 until October 11, 2013 in Pulkovo observatory ( http://www.gao.spb.ru ). We thank those who has already registered ( http://www.gao.spb.ru/russian/psas/ffk2013/part-en.html ), and invite those who has not to do it before August 31. Please, send your abstracts before July 31. ... The main topics of the workshop are: . ...

... 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). ...

... These include support for spectral coordinate systems, and compliance with FITS WCS papers I, II and III. ... Supported . ... Supported (all coordinate systems [including helio-ecliptic] and algorithm codes listed in papers I, II and III, with the exception of the ``STOKES'' and ``COMPLEX'' values defined in paper I, the ``CUBEFACE'' value defined in paper II, and the ``-TAB'' algorithm defined in paper III) . ... Supported (all systems, except ecliptic coordinates are currently assumed to be FK5) ....

... In addition to time, frequency, and scale, there are two other coordinate axes within this transform space: shear-in-time (obtained through convolution with a q-chirp) and shear-in-frequency (obtained through multiplication by a q-chirp). Signals in this multidimensional space can be obtained by a new transform which we call the ``q-chirplet transform'', or simply the ``chirplet transform''. ... CHIRPLET TRANSFORM SUBSPACES . ...

... This task converts an EPIC PN raw events file (produced by epframes and badpix ) into a calibrated event list with flagged trailing events and corrected for gain variations of the preamplifier channels and charge transfer inefficiency (CTI). It performs a pattern analysis to identify and recombine split events and converts the raw unlinearized detector coordinates into corresponding physical locations. ...

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. ... So, I suggest to implement the 1st Theremin Concert for Aliens from Arecibo or Evpatoria Radar facility. ... The theremin was invented 80 years ago, in 1920 by Leon Theremin. ...

Arecibo Proposal No. ... And I guess the primary one-dimensional message is more understandable by unfamiliar aliens and the music is the most universal expression of intellectual activity by means of one-channel ear-like radio link. ... So, I suggest to implement the 1st Theremin Concert for Aliens from Arecibo or Evpatoria Radar facility. ... There were four Messages from Earth to proposed aliens -- two material (Pioneer Plaque and Voyager Record) and two ethereal (Arecibo-1974 and Evpatoria-1999). ...

... 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. ...
