Abstract: |
Reliable prediction of stellar diameters, particularly angular diameters, is a useful and necessary tool for the increasing number of milliarcsecond resolution studies being carried out in the astronomical community. A new and accurate technique of predicting V = 0 and B = 0 apparent angular sizes is presented for both giant and supergiant stars, and for more evolved sources. This technique uses observed K and either V or B magnitudes to predict angular sizes for giant and supergiant stars to 10%; the same technique can be also applied to evolved sources such as Mira variables and carbon stars with results at the 20% level. |
