ROTATION OF STARS AND GAS IN M-82

New observations of near IR emission and absorption lines along M 82's major axis yield radial velocity-position curves that differ markedly from those derived from lines at visible wavelengths. For the central disk we find identical rotation for the -as and the stars, contrary t o earlier results. The rotation derived from emission and absorption l ines at visible wavelengths refer to outer regions of the galaxy since at these wavelengths the central disk is obscured by dust.
