Mass-loss rates of B supergiants from global wind models

How much depends the predicted mass-lost rate due stellar winds on the parameters of the star and how these calculated values ​​correspond to the observed stars? That were question the team of authors (including Jiří Kubát from ASU) was interested in this new paper. A very detailed study shows that some evolutionary stages of the massive stars are still not described satisfactorily, although the nature of the stellar wind and the associated mass-loss rate are very important parameters for the further evolution of the star.

Details can by found in the ASU press release (in Czech).
