Kinematic evidence for different Planetary Nebulae Populations in the elliptical galaxy NGC 4697
Niranjan Sambhus, Ortwin Gerhard, Roberto H. Mendez
We have analysed the magnitudes, kinematics and positions of a complete sample of 320 PNs in the elliptical galaxy NGC 4697. We show (i) that the PNs in NGC 4697 do not constitute…

Oxygen and neon abundances of planetary nebulae in the elliptical galaxy NGC 4697
R. H. Mendez, D. Thomas, R. P. Saglia +3
This paper presents deep spectra of 14 planetary nebulae (PNs) at a variety of angular distances from the center of the flattened elliptical galaxy NGC 4697. Both near the center a…
