Closer look at red supergiant Antares suggests convection not enough to remove surface material
(PHYSorg.com Space & Earth)
 


(Phys.org)-A trio of researchers with Universidad Católica del Norte and the Max-Planck-Institut für Radioastronomie has found evidence that suggests that convection alone cannot account for the amount of material that is pulled from the surface of a red supergiant. In their paper published in the journal Nature, K. Ohnaka, G. Weigelt and K.-H. Hofmann describe their study of the supergiant Antares, what they found and why they now believe there is an unknown force pulling some parts of the star`s surface into space. Gail Schaefer with Georgia State University offers a News & Views piece on the work done by the team in the same journal issue.
