... Maps of six sources (0420+022, 0420-014, 1308+326, 1345+125, 1803+784, and DA 193) obtained with milliarcsecond resolution are presented and discussed, together with their broadband (1­22 GHz) spectra obtained on the RATAN­600 radio telescope at epochs close to those of the VLBI observations. ... The image (Fig. 5) shows that the source structure at 18 cm is compact, consisting of a VLBI core and two jet components, with the outer component lying 5 mas (30 pc) to the northwest of the core ( = 54 ). ...

The Database of Close Binary Systems . ... Team . ... This web-based interactive database is being developed and maintained by a team at the Sternberg Astronomical Institute of the Moscow State University . The project is an on-line extension of our catalogue on "Highly Evolved Close Binary Stars" (volumes I, II) published by Gordon and Breach in 1996. As of September 2009, the database (both the software and the content) is in its development/testing phase. ...
