Stellar Populations in Field Early-Type Galaxies
F. Annibali, A. Bressan, R. Rampazzo +2
We have acquired intermediate resolution spectra in the 3700-7000 A wavelength range for a sample of 65 early-type galaxies predominantly located in low density environments, a lar…
The dynamics of the dE galaxy FS76 : bridging the kinematic dichotomy between Es and dEs
S. De Rijcke, H. Dejonghe, W. W. Zeilinger +1
We present major and minor axis kinematics out to 2 half-light radii for the bright (M_B=-16.7) dwarf elliptical FS76, a member of the NGC5044 group. Its velocity dispersion is 46…
Correlation between kinematics and Hubble Sequence in disk galaxies?
J. C. Vega Beltran, E. Pignatelli, W. W. Zeilinger +4
We present a comparison between ionized gas and stellar kinematics for a sample of 5 early-to-intermediate disc galaxies. We measured the major axis V and sigma radial profiles for…
The kinematics and the origin of the ionized gas in NGC 4036
E. M. Corsini, F. Bertola, M. Sarzi +3
The kinematics of stars and ionized gas has been studied near the center of the S0 galaxy NGC 4036. Dynamical models based both on stellar photometry and kinematics have been built…
Kinematics of Gas and Stars in Early-type Disk Galaxies
J. C. Vega Beltran, E. Pignatelli, W. W. Zeilinger +4
We present a comparison between ionized gas and stellar kinematics for a sample of 5 early-to-intermediate disk galaxies. We measured the major axis V and velocity dispersion radia…
The internal dynamics of very flattened normal galaxies: Stellar distribution functions for NGC 4697
H. Dejonghe, V. De Bruyne, P. Vauterin +1
Using the photometry and the kinematic data, part of which acquired with the NTT, we constructed a 2-integral and a 3-integral distribution function for NGC 4697. We detected a nuc…
