Аннотация:We carried out detailed kinematic studies of the complex of multiple H I and H II shells that represent the only region of ongoing star formation in the dwarf irregular galaxy IC 1613. We investigated the ionized-gas kinematics by using Fabry-Perot H observations with the 6-m Special Astrophysical Observatory telescope and the neutral-gas kinematics by using VLA 21-cm radio observations. We identified three extended (300-350 pc) neutral shells with which the brightest H II shells in the complex of star formation are associated. The neutral-gas kinematics in the complex has been studied for the first time and the H I shells were found to expand at a velocity of 15-18 km/s. We constructed velocity ellipses for all H II shells in the complex and refined (increased) the expansion velocities of most of them. The nature of the interacting ionized and neutral shells is discussed.
