Realistic error estimates on kinematic parameters
V. De Bruyne, P. Vauterin, S. De Rijcke +1
Current error estimates on kinematic parameters are based on the assumption that the data points in the spectra follow a Poisson distribution. For realistic data that have undergon…
On the kinematic signature of a central Galactic bar in observed star samples
P. Vauterin, H. Dejonghe
A quasi self-consistent model for a barred structure in the central regions of our Galaxy is used to calculate the signature of such a triaxial structure on the kinematical propert…
Numerical calculation of linear modes in stellar disks
P. Vauterin, H. Dejonghe
We present a method for solving the two-dimensional linearized collisionless Boltzmann equation using Fourier expansion along the orbits. It resembles very much solutions present i…
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…
The stability of uniformly rotating stellar disks
P. Vauterin, H. Dejonghe
We explore a series expansion method to calculate the modes of oscillations for a variety of uniformly rotating finite disks, either with or without a dark halo. Since all models h…
A method for solving the linearized Boltzmann equation for almost uniformly rotating stellar disks.
P. Vauterin, H. Dejonghe
We construct analytical phase-space solutions for perturbations of flat disks by performing a power series expansion for the radius and the velocity coordinates. We show that this…
