... 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 . ...
