... The metal abundance gradient in the disk of the Galaxy is found from stars with abundance determination from detailed analysis: d[Fe/H]/dR=(-0.05?0.01) kpc -1 . It is shown that the gradient can be explained by the fact that the disk is constituted of two metallicity groups of stars with an abundance jump between the groups. ... По звездам с определениями [Fe/H] из детального анализа найден градиент металличности в диске Галактики: d[Fe/H]/dR=(-0.05?0.01) кпс -1 . ...

The variations of the orbital period of the RS CVn-type binary system SZ Psc are examined through a detailed description of the O-C diagram and the use of a new analysis technique. Continuous changes of very large magnidude have been found. ... A combination of a magnetic activity cycle mechanism and an enhanced stellar wind are found to reproduce satisfactorily the period changes. Key words: orbital period variations - mass transfer - mass loss - third body - magnetic activity ...

In the main part of this lecture, we will give an overview of the theory of fractal strings and of the associated complex fractal dimensions, with emphasis on the case of self-similar strings. ... These oscillations are expressed in terms of suitable explicit formulas (in the sense of number theory, but more general) and yield precise asymptotic expansions for certain geometric, dynamical or spectral counting functions associated to fractal strings. ...

Since the light from galaxies represents the integrated contribution of its consitutient stars, then we can learn about stellar populations in galaxies by modelling their light by summing up individual stellar spectra for different kinds of stars. ... The data cover the wavelength range 3500 - 9000 angstroms. ... Retrieve Digital Stellar Spectra Click on the appropriate spectral type. ... Note that the designation V means main sequence, IV means subgiants, III means giants, I means supergiant. ...

The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...

The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...

. The shell uses a command called test to evaluate conditional expressions. Full details of this command can be found in the test manual page. For example: if test ! -f $FILE then if test "$WARN" = "yes" then echo "$FILE does not exist" fi fi . First, we test to see if the filename specified by the variable $FILE exists and is a regular file. If it does not then we test to see if the variable $WARN is assigned the value yes , and if it is a message that the filename does not exist is displayed.
