J/A+A/18/341        Double stars of equal components         (Stock+, 1972)

Double stars of equal components. Stock J., Wroblewski H. <Astron. Astrophys., 18, 341-349 (1972)> =1972A&A....18..341S (SIMBAD/NED BibCode)
ADC_Keywords: Stars, double and multiple ; MK spectral classification Keywords: Double stars - equal components Abstract: A list of 271 double stars of nearly equal components with separations up to about one minute of arc is given. Their physical nature is demonstrated by their spectral type distribution which coincides with that of close double stars of equal components, but differs from that of general field stars.
