Low frequency catalogues of the CATS database
O. V. Verkhodanov, S. A. Trushkin, H. Andernach
The authors describe the largest existing publicly accessible radio source database CATS (``astrophysical CATalogues Supporting system''; http://cats.sao.ru). CATS contains more th…
The problem of identifying decametric sources
O. V. Verkhodanov, H. Andernach, N. V. Verkhodanova
We describe a method to construct continuum spectra for radio sources on the basis of entries from various source catalogues in comparatively large error boxes around a given sky p…
The formation of asymmetries in Multiple Shell Planetary Nebulae due to interaction with the ISM
E. Villaver, A. Manchado, G. Garcia-Segura
Multiple shell planetary nebulae (MSPNe) are most likely a consequence of the modulation of the mass-loss rate during the thermal pulses on the AGB. By using numerical simulations…
Bose-Einstein Condensation in a Constant Magnetic Field
H. Perez, L. Villegas
We discuss the occurrence of Bose-Einstein condensation in systems of noninteracting charged particles in three in one dimensions and in presence of an external magnetic field. In…
Magneto-rotational and thermal evolution of magnetars with crustal magnetic fields
U. Geppert, D. Page, M. Colpi +1
Soft Gamma-ray Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs) are interpreted as young highly magnetized neutron stars (NSs). Their X-ray luminosity in quiescence, exceeding 1…
Search for optical microvariability in a large sample of Seyfert I galaxies
P. O. Petrucci, A. Chelli, G. Henri +3
We present results of an optical (I band) monitoring of a sample of 22 Seyfert I galaxies. We aimed to detect microvariability with time resolution from ~ 6 minutes down to 30 seco…
