Diameters of O Type Stars Based on Ultraviolet Observations

摘要

Using the ultraviolet flux obtained by the TD-1 satellite and assuming the Planck radiation law, the diameters of 0 type stars were calculated. These values are shown to be in good agreement with the earlier values obtained by direct techniques and indirect methods. Using this method diameters are also calculated for some 0 stars for which no previous data are available.
