Abstract
Compression of the interstellar gas by a passing density-wave is thought to be responsible for triggering the presently observable star formation processes in the arms of spiral galaxies. We present new observations of the distribution and kinematics of the Hβ emission in the spiral arms of M83, obtained with the TAURUS imaging Fabry-Pérot system. These results, when combined with observations of the neutral and molecular components with sufficiently high resolution, should contribute to our understanding of the time sequence by which stars form out of the interstellar gas.
