... In this case the F5-F9 dwarfs turn out to be more metal-rich (by 0.1 in [Fe/H] ) thab G and K dwarfs, and the metallicity of the Hyades cluster turns out to be larger than the solar one [Fe/H] Hyades =+0.1 . ... При этом карлики F5-F9 оказываются богаче металлами, чем более поздние звезды, примерно на 0.1 по [Fe/H] , и металличность звезд Гиад относительно Солнца равна [Fe/H] Hyades =+0.1 . ...

... A demonstration of HST WFPC image restoration has been made using both empirical and simulated PSFs. Empirical PSFs are obtained from the WFPC PSF library and also extracted from the image to be restored. ... The best results obtained thus far rely upon being able to determine a high S/N empirical PSF from the data frame. In order to achieve accurate restorations of data with high dynamic range excellent PSF models are required. ... Keywords: image restoration, HST WFPC image, PSFs . ...

... The object is remarkable because of its low estimated mass and age and because it is associated with a mid-infrared source, an indication of a surrounding dusty disk. Based on the comparison of our spectrum with similar spectra of field M-dwarfs and atmospheric models, we obtain revised estimates of the spectral type, effective temperature and luminosity of the central object. ...

We investigate models for main-sequence and horizontal-branch (HB) stars constructed using the Carson opacities and make comparisons with models based on the Cox-Stewart opacities. ... The drop in the hydrogen-shell luminosity due to the helium-core expansion during HB evolution is greater than that obtained with the Cox-Stewart opacities. ... Studies of main-sequence (MS) stars lead to agreement with Stothers' (1974a,b, 1976) results for homogeneous models constructed with Carson opacities. ...

... Comparative study of Tl-2201 single crystals with different temperatures of superconducting transition by means of specific heat method. Abstract: . The comparison studies of the specific heat of Tl-2201 single crystals with the different oxygen concentration have led to the conclusion that the doping by oxygen, resulting in lowering of T c and increasing of number of paramagnetic centers, leads to diminishing of antiferromagnetic correlations contribution to the specific heat. ...

... These sources are much more likely to be gravitationally lensed by intervening galaxies as compared with sources discovered in surveys in other wavebands. ... The effect of lensing by clusters is then discussed briefly. This is expected to increase the source confusion noise in a Planck survey in the directions of clusters, and could provide information about galaxies with flux densities that are too faint to be detected directly by Planck . ... 2 The properties of galaxy--galaxy lensing . ...

... Study of Mg-Fe-silicate glasses of variable composition. ... With the new data, the astrophysical discussion started in Paper I was continued and focussed on the comparison of the olivine glass data with IRAS LRS spectra of O-rich circumstellar envelopes around Mira stars. ... The new olivine glasses point to the interesting consequence that the temperature for silicate dust grains at the inner edge of circumstellar envelopes must be considerably higher than the values often given in the literature....

PERFORMANCE COMPARISION OF KODAK DCS460 DIGITAL CAMERA AND PIXELVISION BACK-ILLUMINATED CCD . ... ABSTRACT : A Kodak DCS460 digital camera (with 1300 x 1000, 9-micron square pixels) and a PixelVision, back-illuminated digital CCD camera (with 1024 x 1024 elements, 12-micron square pixels) were tested at calibrated light levels ranging from 10 -2 footcandles to 10 -5 footcandles. The PixelVision back-illuminated CCD was shown to be 10,000 more sensitive than the Kodak DCS460 CCD camera. ...

... The DAL is essentially implemented in C++. The design takes the form of a set of abstract classes which provides the fundamental DAL interface. There are currently two implementations (both in C++) of this abstract interface; one is the High Memory Model and the other is the HighLow Memory Model. ... In particular, an understanding of the C++ class hierarchy will lead to more generic algorithms e.g. use BlockT rather than ArrayT if only the BlockT methods are needed. Class Hierarchy . ...

... Dust in the region is studied photometrically at ultraviolet, optical, and far-infrared wavelengths to analyze nebular colors, grain properties, and scattering geometry. Constraints on this geometry are provided by spectroscopy of radio emission lines and optical absorption lines of the interstellar gas, which also reveal a significant amount of fine-scale filamentary structure. ...
