Investigation of radius anomalies among short-period Cepheids
Journal Article

· Astrophys. J.; (United States)
Simultaneous photometric and spectroscopic observations have been obtained of two short-period Cepheids, SU Cas and TU Cas. The Wesselink method of Barnes et al. was used to obtain radii. The radii are found to agree, within the expected error, with evolutionary values. This strengthens the argument that the beat Cepheids are normal Cepheids in mixed-mode behavior rather than a separate class of objects and that evolutionary masses and radii are correct.
