Electric fields at the quark surface of strange stars in the color-flavor locked phaseAug 12 2004Oct 14 2004It is shown that extremely strong electric fields may be generated at the surface of strange quark matter in the color-flavor locked phase because of the surface effects. Some properties of strange stars made of this matter are briefly discussed.
On the persistent X-ray emission from the soft gamma-ray repeatersDec 10 1996It is suggested that the persistent X-ray emission from the soft gamma-ray repeaters is the thermal radiation of neutron stars which is enhanced by a factor of 10 or more due to the effect of a very strong magnetic field on the thermal structure of the ...

Experimental study of a transformer with superconducting elements for fault current limitation and energy redistributionApr 19 2005Numerous proposed and developed superconducting fault current limiters and self-limiting transformers limit successfully fault currents but do not provide uninterrupted supplying of consumers. A design investigated in the work combines the functions of ... More
Young Stars in the Camelopardalis Dust and Molecular Clouds. I. The Cam OB1 AssociationMar 17 2008Mar 31 2008The distribution of dust and molecular clouds in the direction of Galactic longitudes 132--158 deg and latitudes pm 12 deg is investigated. The maps of dust distribution in the area were plotted from the following surveys: the star counts in the DSS I ... More
A narrow plane cut near the crystal surface increases the probability of capture into the stable channeling motion up to 99 percentMar 07 2007It is shown that a narrow plane cut near the crystal surface considerably increases the probability of capture into the stable channeling motion of positively charged particles entering a crystal at angles smaller than a quarter of the critical channeling ...

The Carlitz AlgebrasMay 18 2005The Carlitz $\mathbb{F}_q$-algebra $C=C_\nu$, $\nu \in \mathbb{N}$, is generated by an algebraically closed field $\CK $ (which contains a non-discrete locally compact field of positive characteristic $p>0$, i.e. $K\simeq \mathbb{F}_q[[ x,x^{-1}]]$, $q=p^\nu$), ...

On the instability of classical dynamics in theories with higher derivativesDec 25 2006Jan 09 2007The development of instability in the dynamics of theories with higher derivatives is traced in detail in the framework of the Pais-Uhlenbeck fourth oder oscillator. For this aim the external friction force is introduced in the model and the relevant ... More
Boundary conditions at spatial infinity for fields in Casimir calculationsNov 02 2005The importance of imposing proper boundary conditions for fields at spatial infinity in the Casimir calculations is elucidated.
The Association of PSR B1757-24 and the SNR G5.4-1.2Oct 14 2003The association of PSR B1757-24 and the supernova remnant (SNR) G5.4-1.2 was recently questioned by Thorsett et al. (2002) on the basis of proper motion measurements of the pulsar and the "incorrect" orientation of the vector of pulsar transverse velocity ... More
On the origin of the hypervelocity runaway star HD271791Sep 27 2009We discuss the origin of the runaway early B-type star HD271791 and show that its extremely high velocity (\simeq 530-920 km/s) cannot be explained within the framework of the binary-supernova ejection scenario. Instead, we suggest that HD271791 attained ... More
Neutron Stars in Supernova Remnants and BeyondDec 26 2002We discuss a concept of off-centred cavity supernova explosion as applied to neutron star/supernova remnant associations and show how this concept could be used to preclude the anti-humane decapitating the Duck (G5.4-1.2 + G5.27-0.9) and dismembering ...

Explicit solution of the problem of equivalence for some Painleve equationsSep 10 2009For an arbitrary ordinary second order differential equation a test is constructed that checks if this equation is equivalent to Painleve I, II or Painleve III with three zero parameters equations under the substitutions of variables. If it is true then ... More
Installing of cosmological constantAug 05 2013Jan 14 2014An artificial scale of observable cosmological constant is dynamically related to its natural bare value due to an installation of relevant coherent state for the inflationary field in a finite volume of early Universe, because of exponential suppression ...

Extra charmonium states as bag-quarkoniaMay 28 2008Jun 06 2008Exotic states in the charmonium family are systematically treated in the framework of simplest model with an effective coulomb-like interaction of heavy quark and antiquark in the presence of static excitation of quark-gluon modes responsible for a nonperturbative ...

A quantum mass-spectrum of Kerr black hole: superstringsDec 23 2004Jan 12 2005Using thermal quantization of geodesics confined under horizons and reasonable conjecture on massless modes, we evaluate quantum spectrum of Kerr black hole masses compatible with superstring symmetries.
Radial geodesics as a microscopic origin of black hole entropy. II: Features of Reissner--Nordstrom black holeDec 21 2004Jan 04 2005The entropy of charged black hole is calculated by using the partition function evaluated at radial geodesics confined under horizons. We establish two quantum phase states inside the black hole and a transition between them.
