Imaging of the core of the OMC-1 region using NICMOS camera 2 through the F212N and F215N filters shows a wide variety of interesting structure on scales of 0.2" at a very high dynamic range (Stolovy et al. ... The application of image restoration techniques, including multi-channel variants of the Richardson-Lucy technique, offers the chance to enhance structure on the finest scales and also to suppress the prominent and richly structured point-spread functions of the many bright stars in the...
... 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). ...
