... The main field of my investigations is stellar spectrophotometry. As a result of scientific activity of our group spectrophotometric catalog was created including energy distribution data on 900 stars in the range 3200-7600AA and 250 stars in the range 6000-10800AA (Voloshina et al., Spectrophotometry of Bright Stars, ed. I.N.Glushneva, 1982, Moscow, Nauka, in Russian). ...

... The first two catalogues (the one has been calculated using all input catalogues and the second one using only catalogues obtained with CALC/SOLVE software) provide a stochastic improvement of the ICRF 2. and the last two of them one allow us to account also for systematic errors in the current ICRF version. ... Input Catalogues and Comparisons Table 1. ... In result, the combined catalogue PUL08C01a and PUL08C01b (only input catalogues constructed using CALC/SOLVE were used) were constructed. ...

Classroom Activity: Pinhole Protractor Gene Byrd and Renato Dupke . ... We cannot directly perceive the distances or sizes of far-away objects. Instead, our eyes only detect the angular size of objects. ... In Part II, which will appear in a future issue of The Universe in the Classroom, students will see how astronomers use parallax -- an extension of binocular vision -- to determine the distances of stars in the Sun's neighborhood. ... distance = 57.3 x physical size angular size (in degrees). ...

. F IGURE . 6. Properties of metal-poor subsystems of RR Lyraes with low peculiar velocity (top row) and high peculiar velocity (bottom row). The first column shows histograms in the rotation velocities. The second column shows the distribution of Z (see text for details), and the curves approximate the reconstructed distributions with exponential law The third column shows relations between maximum height above the galactic plane and metallicity. discussion in the text | privious figure | next figure .

... Polish scientists at the Space Research Centre, Polish Academy of Sciences, in Wroclaw, south-west Poland, have constructed an instrument called SphinX (short for Solar PHotometer In X-rays), which is an X-ray spectrophotometer, that will obtain spectra in the energy range 0.5--15 keV in 256 energy channels with frequency of up to 100 times a second. ... SphinX is part of a package of instruments known as TESIS (PI Prof. Sergei Kuzin, Lebedev Institute, Moscow). ... Space Research Centre, . ...
