J/ApJS/59/95 Visual multiples. VIII. (Abt+, 1985) ================================================================================ Visual multiples. VIII. 1000 MK types. Abt H.A. =1985ApJS...59...95A ================================================================================ ADC_Keywords: MK spectral classification ; Stars, double and multiple Keywords: stars: spectral classification - stars: visual multiples Abstract: A total of 1000 new classifications are given for stars brighter than B=8.0mag in the Aitken double star catalog. The classifications supplement 865 classifications obtained in 1981 and 1984. Among the newly discovered stars are 12 new Ap stars, eight Lambda Bootis stars, one Ba II star, and 60 Am stars. A detailed list of the new classifications is given.

HD 34078 apparently no longer considered a (visual) double. HD 168815 referenced type is from Morgan & Keenan (1973ARA&A..11...29M), not Miskin, who didn't observe this part of the sky. HD 186927 Stephenson type is K0II-III, not M0III-III. HD 220363 apparently no longer considered a (visual) double. Acknowledgements: This catalog was prepared and checked by Brian Skiff.
