Constraints on rotation of B-type stars from the nitrogen abundance
Instytut Astronomiczny, Uniwersytet Wroclawski, ul. Kopernika 11, 51-622 Wroclaw, Poland
Published online: 8 September 2017
We study the effects of rotation on surface abundances of CNO elements in massive stars. Nitrogen enrichment caused by rotationally induced mixing can help to constrain parameters of observed stars, especially their rotational velocities. Here we present theoretical results and apply them to the star HD 163899.
