Abstract:
We present kinematics of 135 planetary nebulae (PNs) in M31 from a
survey covering 3.9°2 and extending out to 15kpc from the
southwest major axis and more than 20kpc along the minor axis. The
majority of our sample, even well outside the disk, shows significant
rotational support (mean line-of-sight velocity 116km/s).
Description:
Imaging of M31 was carried out at the Case Western Reserve University
Burrell Schmidt on the nights of 2000 September 23-30.
