Observations of supergiant stars in the Small Magellanic Cloud.
Abstract
Spectrographic and photometric data are presented for 91 supergiant stars belonging to the Small Magellanic Cloud and its Wing. The data include MK classes for 52 stars, radial-velocity data for 51 stars, and UBV photometry for 90 stars. In V the limiting magnitude for the spectrographic observations is 13.7 and for the photometric observations, 13.9. Whenever possible, radial velocities for interstellar Ca II and forbidden O II have been measured and listed. Notes are given for the individual stars concerning the data obtained and comparisons with results of previous investigations.
