We perent radio flux measurements at 5 GHz for a sample of RS CVn-type chromospherically active binary systems made from 1988 to 1992 using the NRAL broad-band interferometer (BBI). The derived radio luminosities are consistent with previous observations but show that radio flaring is a common feature which will affect the results of rotation-activity studies. ... Key words: stars: activity - stars: late type - stars: binaries: close - stars: flare - stars: variables - stars: radio continuum ...

... PUL2 catalog contains original absolute proper motions of 59646 stars in 149 fields with galaxies. ... Mean errors of relative proper motions in PUL2 catalog is 5.5 mas/year. ... The external mean error of one relative proper motion of a bright star of PUL2 catalog is 9 mas/year for both of coordinates. ... After issue of UCAC2 catalog, we decided to improve accuracy of proper motions, using Pul-3 coordinates (of 1950s) as the first epoch, and UCAC2 coordinates as the second epoch. ...

This all-sky image shows the spatial distribution over the whole sky of the galactic haze at 30 and 44 GHz, extracted from the Planck observations. In addition to this component, other foreground components such as charged particles accelerated radially, known as synchrotron radiation, thermal dust, spinning dust, and extragalactic point sources contribute to the total emission detected by Planck at these frequencies. ...

... Seminar archive . ... The structure of the X-ray sources in the hard spectral state of accreting black-hole binaries has been a subject of intense debate. The paradigm dominant for many years postulated that the accretion disc in the hard state is truncated at some radius >> the innermost stable orbit (ISCO) whereas the disc reaches the ISCO in the soft state. ... On the other hand, there have been numerous claims in recent years that the disc extends to the ISCO in the hard state. ...
