... Formation of large-scale inhomogeneous magnetic structures in a turbulent convection". ... Magnetic fluctuations generated by a tangling of the mean magnetic field by velocity fluctuations are studied in a developed turbulent convection with large magnetic Reynolds numbers. ... This effect is caused by a negative contribution of the turbulent convection to the effective mean Lorentz force. ... The energy for this instability is supplied by the small-scale turbulent convection. ...

Top] [Prev] [Next] . Recent results of timing observations of the planets pulsar, PSR B1257+12, are discussed. ...

The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ... Particle size expressed in units of the wavelength of incident radiation, together with chemical composition, most strongly affects the optical properties of a scatterer. ... There are many methods to solve the light-scattering problem for a homogeneous spheroid (our survey of the light-scattering methods see here ). ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...

... It was found that the Sun lies 9?2 pc above the plane of hte Galactic disk in the direction of North Galactic pole and that F0-F9 stars contribute 0.0035 M /pc 3 to the density of the Galactic disk. ... We used this method to determine the scale height of the subsystem of F stars of the Galactic disk, Z 0 =160?10 pc. ... It is suggested that scale height of the metal-poor stars subsystem is due to the infall of the metall-poor intergalactic gas onto the disk. ...

Visual Discovery of SN1995V in NGC 1087. ... My basic supernova search still continues with my backyard 41cm telescope. ... The discovery of supernova 1995V in NGC 1087 is the second discovery to be made this year with the larger telescope. ... After this, they took two CCD pictures of NGC 1087 from which the magnitude of the supernova could be calculated in relation to a nearby measured star, and the offsets of the supernova could also be measured. ...

... Programme . ... Abstract: We reveal the stellar light originating from the kiloparsec-scale, ring-like structure of the Centaurus A galaxy in unprecedented detail. In particular, we use sub-arcsecond resolution near infrared images to create a dust-free view of this structure that is heavily obscured by the central dust lane at visual wavelengths. ... Finally, we discuss the large-scale geometry implied by the reddening signatures of dust in our near infrared images. go back . ...
