The velocity dispersion of LMC Carbon stars: possible detection of a kinematically distinct population
David S. Graff, Andrew P. Gould, Nicholas Suntzeff +2
We analyze the velocity residuals of 551 carbon stars relative to a rotating-disk model of the inner of the Large Magellanic Cloud (LMC). We find that the great…

The Stellar Populations of Spiral Disks. I. A New Observational
D. Beauchamp, E. Hardy
We describe an imaging method that makes use of interference filters to provide integrated stellar spectral indices for spiral disks to faint surface brightness limits. We use filt…
