The H I chronicles of LITTLE THINGS BCDs: evidence for external perturbations in the morphology and kinematics of Haro 29 and Haro 36.

ASHLEY T., SIMPSON C.E. and ELMEGREEN B.G.

Abstract (from CDS):

We analyze high angular and velocity resolution H I line data of two LITTLE THINGS blue compact dwarfs (BCDs): Haro 29 and Haro 36. Both of these BCDs are disturbed morphologically and kinematically. Haro 29's H I data reveal a kinematic major axis that is offset from the optical major axis, and a disturbed outer H I component, indicating that Haro 29 may have had a past interaction. Position-velocity diagrams of Haro 36 indicate that it has two kinematically separate components at its center and a likely tidal tail in front of the galaxy. We find that Haro 36 most likely had an interaction in the past, is currently interacting with an unknown companion, or is a merger remnant.
