... BLUE STRAGGLER STARS are unusually hot and bright stars found in the cores of ancient star clusters known as globulars. ... BACKGROUND (from wikipedia): Blue straggler stars are stars in open or globular clusters that are hotter and bluer than other cluster stars having the same luminosity. ... There is evidence in favor of this view, notably that blue straggler stars appear to be much more common in dense regions of clusters, especially in the cores of globular clusters. ...

From the Cosmos-1809, Intercosmos-19 and Cosmos-900 satellite data the ring ionospheric trough, RIT, associated with the ring magnetospheric current and SAR-arcs was revealed and its characteristic were in detail investigated. ... The occurrence probability dependence of the both troughs on season, local time, longitude and magnetic activity was investigated. ...

Polycyclic aromatic hydrocarbons in HII regions: correlation with metallicity . ... We have perfomed the aperture photometry of HII regions using infrared images from telescopes Spitzer and Herschel at passbands 3.6, 4.5, 5.8, 8.0, 24, 70 and 160 m. Emission of PAHs are observed at passbands 3.6 - 8.0 m, 24 m is emission likely of hot small particles and finally large particles are responsible for emission at 70 and 160 m. We determine abundances of PAHs using model of Draine Li (2007) . ...

... Theoretical investigation was carried out of electron transport phenomena in superconducting heterostructures S-MB-N and S-MB-S with magnetic barriers (MB) determined by monolayer of ferromagnet (F) or spin-valve structures FNF or FIF (N is a normal metal, I is insulating layer). ... The I-V characteristics of cuprate bicrystal Josephson junctions have been experimentally investigated at different temperatures, barrier transparency factors and the phase difference of superconducting electrodes. ...

... We also take care to characterise the flat fields, especially their colour dependence, to very high precision which enables high precision photometry even without autoguiding. ... The Blue Diamond Effect The blue diamond effect is caused by surface imperfections on the silicon chip introduced during manufacture, resulting in a repeated large scale pattern in the flat field at blue wavelengths. ... We can remove the blue diamond by using a colour appropriate flat field produced in the lab. ...

... Fit the ring around the equator and then change its inclination from 0 degrees (equatorial orbit used by geosynchronous satellites) to 28.5 degrees (space shuttle orbit) to 51.6 degrees (space station orbit) to 90 degrees (polar orbit used by spy satellites). by Rob Landis, Space Telescope Science Institute . ...

... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...
