Spectral classification at ultra-low dispersion

  • 28 Accesses

Abstract

We demonstrate here the possibility of using very low dispersion (10000 Å mm−1) slitless spectroscopy of stars for a fairly accurate spectral classification. The technique is shown to be very useful in studies of star clusters.
