2658 20160701171708.0 ASTROimport-815 Zorec, J. 2005 Achernar can be a differential rotator We take advantage of interferometric measurements of Achernar to inquire on its internal rotational law. The reinterpretation of interferometric data and the use of fundamental parameters corrected for gravitational darkening effects and 2D-models of internal stellar structures, lead us to the conclusion that the star could not be a rigid, near critical, rotator but a differential rotator with the core rotating ˜3 times faster than the surface.
