The two-dimensional internal rotation of KIC 11145123.

HATTA Y., SEKII T., TAKATA M. and KURTZ D.W.

Abstract (from CDS):

The 2D internal rotation of KIC 11145123 has been inferred via asteroseismology. Based on the optimally localized averaging method and a simple three-zone modeling of the internal rotation, we have found evidence for a contrast between the internal rotation of the radiative region and that of the convective core; the radiative region rotates almost uniformly throughout the region, but the convective core may be rotating about 6 times faster than the radiative region above. We have also found marginally significant evidence of latitudinal differential rotation in the outer envelope. These newly indicated features of the internal rotation of the star can help us further constrain the theory of angular momentum transport inside stars, as well as understand the complex physical properties of the star, which was once thought to be a main-sequence A-type star but recently has been proposed to be a blue straggler, based on spectroscopy.
