III/106     Visual Multiples. VII. MK Classifications (Abt 1981)
================================================================================
Visual Multiples. VII. MK Classifications
    Abt H.A.
    <Astrophys. J. Suppl., 45, 437 (1981)>
    =1981ApJS...45..437A
================================================================================
ADC_Keywords: Stars, double and multiple; MK spectral classification; Spectral
    types

Abstract:
   Classifications are given for 865 components of visual multiples; they show
   no systematic differences from the MK system, and the random errors are one 
   subclass in type and two-thirds of a luminosity class.

   Fields given include ADS, HD and HR identification, MK classifications, 
   luminosity classes, alternative names, selected published spectral types
   and references.
