... Sagittarius Star Cloud . ... Stars come in all different colors. ... Most stars in the above Sagittarius Star Cloud are orange or red and relatively faint, as our Sun would appear. ... Stars like HD 82943 are main sequence G dwarf stars with temperatures and compositions similar to the Sun. Also like the Sun, HD 82943 is known to have at least two giant planets, but unlike gas giants in our solar system their orbits are not nearly circular and bring them closer to the parent star. ...

... While there is practically no detector noise present at energies above , X-ray data below are considerably contaminated by noise events, which become more and more dominant towards the lowest transmitted energies (Fig. ... Investigations of 40 hours of in-orbit calibration data with the filter wheel closed, taken over a period of more than two years, showed that the noise properties vary with position and energy, but are fairly stable in time for most areas on the detector. ...

... We study ergodic properties of random maps defined as collections of nonsingular maps $f_1,\dots,f_w$ from a compact metric space $(X,\rho)$ into itself taken with probabilities $p_1,\dots,p_w$ ($\sum_i^wp_i=1$) and considered as Markov processes on $X$. ... In the first situation, when the random map is expanding on average, we mainly follow ideas borrowed from the theory of piecewise expanding maps and the corresponding Banach space is a version of the space of functions of bounded variation on $X...

Authors: Yu.G. Shevelev , V.A. Marsakov , . ... We have constructed and investigated properties of metallicity function of disk stars with different ages, proceeding from the statistically restored real altitude distributions of stars at the solar galactocentric distance. It is shown that the metallicity distribution of stars in each age range is not of Gaussian form, but it may be considered as a superposition of two normal distributions centered at -0.2 and 0.0 dex. ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...
