Next: A Coronagraphic Search for Up: NICMOS Science Previous: NICMOS Science . ... A search for previously unknown low-mass (giant planet and brown dwarf) companions to stars in the solar neighborhood, and circumstellar dust disks around main sequence stars by direct coronagraphic imaging has been undertaken by the NICMOS Instrument Definition Team (IDT). ... The problem in the target acquisition process resulted in degraded pointing and target centration performance for these observations. ...

... 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). ...
