The kinematics and distribution of H I in IC 10.

WILCOTS E.M. and MILLER B.W.

Abstract (from CDS):

We present the results of an extensive study of the neutral hydrogen content of IC 10, a dwarf irregular in the Local Group that is rightly considered a starburst. The H I content of IC 10 is characterized by a regularly rotating disk embedded within an extended and complex distribution of gas. The distribution of gas within the disk is dominated by holes and shells and has been and continues to be shaped by stellar winds associated with the numerous Wolf-Rayet and O stars. The stellar winds have likely triggered secondary generations of star formation within the shells surrounding many of the holes. We have detected the kinematic signature of the previously reported young superbubble in a large H I cloud at the southeastern tip of the optical galaxy. Finally, the complex distribution and kinematics of the extended gas around IC 10 suggest that this is a galaxy that is still forming via the accretion of the surrounding gas.
