    A new classification scheme for B-type stars
    The criteria for spectral classification of B-type stars were established almost 80 years ago from low-resolution spectra on photographic plates. Since...

    A New Code for Automatic Determination of Equivalent Widths: Automatic Routine for Line Equivalent Widths in Stellar Spectra (ARES)
    We present a new automatic code (ARES) for the determination of equivalent widths of absorption lines present in stellar spectra. We also describe its use for...

    A new era in galaxy edge characterisation with ultra-deep imaging
    For the first time, the LIGHTS survey is routinely imaging galaxies at a depth and spatial resolution comparable to what LSST will produce in 10 years (i.e. ~31...

    A new information system at the IAC and ING.
    Information about telescopes, instruments and facilities at the IAC and ING is now electronically accessible through the Gopher utility.
  • Publication
    A new ionization correction scheme for He(+)/H(+) and the determination of the helium abundance in H II regions
    A new ionization correction factor (ICF) scheme for He(+) is developed, based on the definition of the radiation softness parameter eta (Vilchez and Pagel, 1988...

    A New Measurement of the 6Li / 7Li Ratio in HD 82943
    We investigate the presence of possible blends in the spectral region of the Li resonance line at 6708Å in solar-type metal-rich stars using high resolution and...
