... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it’s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ... Some stars as Pollux show a spectrum similar to that of our sun with strong Ca II and Fe II lines, others as Sirius or Vega show strong absorption lines of hydrogen, others, as Mira show very complicated spectra due to molecular absorption lines (see figure 5). ...

. The smaller circle is the sigma+systematic Fermi GBM error box, and another circle is the 3sigma+systematic Fermi GBM error box).

Prague, August 16, 2006 . Another problem that was making it difficult to automatically merge GCVS and survey catalogs has been recently solved: 'old' variable stars also had only very rough coordinates. The GCVS has been identified, on a star-by-star basis, with positional catalogs. ... The total number of stars we were unable to identify, at least tentatively, is only 200, most of them from two or three sources of especially unreliable positional information. ...

The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...
