Five-colour photometry of supergiants and the dust-to-gas ratio in the Large Magellanic Cloud.
Abstract
A discussion is presented of photo-electric five-colour observations of about 70 supergiants made in 1966. Sllght photometric differences between these supergiants and those in our galaxy need further confirmation. The dust-to-gas ratio in the LMC appears to be about four times smaller than in the Galaxy. Key words: photometry - supergiants - - dust-to-gas ratio
