Double Pair Production by Ultra High Energy Cosmic Ray Photons
S. V. Demidov, O. E. Kalashev
With use of CompHEP package we've made the detailed estimate of the influence of double e+e- pair production by photons (DPP) on the propagation of ultra high energy electromagneti…
Shape parameters of Galactic open clusters

There is a robust upper limit on the energy of synchrotron radiation in high-energy astrophysics: , where is the fine structure constant and the…
HeII->HeI Recombination of Primordial Helium Plasma Including the Effect of Neutral Hydrogen
E. E. Kholupenko, A. V. Ivanchik, D. A. Varshalovich
The HeII->HeI recombination of primordial helium plasma (z = 1500 - 3000) is considered in terms of the standard cosmological model. This process affects the formation of cosmic mi…
Discovery of very low amplitude 9-minute multiperiodic pulsations in the magnetic Ap star HD 75445
O. Kochukhov, S. Bagnulo, G. Lo Curto +1
We present our discovery of pulsational radial-velocity variations in the cool Ap star HD 75445, an object spectroscopically similar to the bright, rapidly-oscillating Ap (roAp) st…
Star-forming cores embedded in a massive cold clump: Fragmentation, collapse and energetic outflows
Martin Hennemann, Stephan M. Birkmann, Oliver Krause +4
The fate of massive cold clumps, their internal structure and collapse need to be characterised to understand the initial conditions for the formation of high-mass stars, stellar s…
Toward mode selection in Delta Scuti stars: Regularities in observed and theoretical frequency spectra
M. Breger, P. Lenz, A. A. Pamyatnykh
Only a fraction of the theoretically predicted nonradial pulsation modes have so far been observed in Delta Scuti stars. Nevertheless, the large number of frequencies detected in r…
CMB anisotropy induced by tachyonic perturbations of dark energy
M. V. Libanov, V. A. Rubakov, O. S. Sazhina +1
We study effects of possible tachyonic perturbations of dark energy on the CMB temperature anisotropy. Motivated by some models of phantom energy, we consider both Lorentz-invarian…
Sensitivity of cosmic-ray experiments to ultra-high-energy photons: reconstruction of the spectrum and limits on the superheavy dark matter
O. E. Kalashev, G. I. Rubtsov, S. V. Troitsky
We estimate the sensitivity of various experiments detecting ultra-high-energy cosmic rays to primary photons with energies above 10^19 eV. We demonstrate that the energy of a prim…
Stellar dynamos with effect
V. V. Pipin, N. Seehafer
We study axisymmetric mean-field dynamo models containing differential rotation, the effect and the additional turbulent induction effects. The additional effects result from t…
Distances and peculiar velocities of spiral galaxies in the 2MFGC and SFI++ samples
Yu. N. Kudrya, V. E. Karachentseva, I. D. Karachentsev +2
We compare infrared Tully-Fisher (TF) distances and peculiar velocities derived for spiral galaxies from the two largest datasets: the 2MASS selected Flat Galaxy Catalog, 2MFGC [19…
Rotating molecular outflows: the young T Tauri star in CB26
R. Launhardt, Ya. Pavlyuchenkov, F. Gueth +7
The disk-outflow connection is thought to play a key role in extracting excess angular momentum from a forming proto-star. Though jet rotation has been observed in a few objects, n…
Non-LTE line formation for Pr II and Pr III in A and Ap stars
L. Mashonkina, T. Ryabchikova, A. Ryabtsev +1
Non-LTE line formation for Pr II and Pr III is considered through a range of effective temperatures between 7250 K and 9500 K. A comprehensive model atom for Pr II/III is based on…
Science with the World Space Observatory - Ultraviolet
Ana I. Gomez de Castro, Isabella Pagano, Mikhail Sachkov +4
The World Space Observatory-Ultraviolet (WSO-UV) will provide access to the UV range during the next decade. The instrumentation on board will allow to carry out high resolution im…
A likely optical counterpart of the G292.0+1.8 pulsar wind nebula
S. V. Zharikov, Yu. A. Shibanov, D. A. Zyuzin +2
G292.0+1.8 is the Cas A-like supernova remnant containing the young pulsar PSR J1124-5916, which powers a compact torus-like pulsar wind nebula with a jet visible in X-rays. We hav…
A Unified Monte Carlo Treatment of Gas-Grain Chemistry for Large Reaction Networks. I. Testing Validity of Rate Equations in Molecular Clouds
A. I. Vasyunin, D. A. Semenov, D. S. Wiebe +1
In this study we demonstrate for the first time that the unified Monte Carlo approach can be applied to model gas-grain chemistry in large reaction networks. Specifically, we build…
