A new method based on Markov chains for deriving SB2 orbits directly from their spectra
J. -B. Salomon, R. Ibata, P. Guillout +7
We present a new method to derive orbital elements of double-lined spectroscopic binaries (SB2). The aim is to have accurate orbital parameters of a selection of SB2 in order to pr…
Gaia and the dynamics of the Galaxy
Benoit Famaey
Gaia is an ambitious ESA space mission which will provide photometric and astrometric measurements with the accuracies needed to produce a kinematic census of almost one billion st…
Unifying all mass discrepancies with one effective gravity law?
HongSheng Zhao, Benoit Famaey
A remarkably tight relation is observed between the Newtonian gravity sourced by the baryons and the actual gravity in galaxies of all sizes. This can be interpreted as the effect…
The properties of the local spiral arms from RAVE data: two-dimensional density wave approach
A. Siebert, B. Famaey, J. Binney +19
Using the RAVE survey, we recently brought to light a gradient in the mean galactocentric radial velocity of stars in the extended solar neighbourhood. This gradient likely origina…
Isolated and non-isolated dwarfs in terms of modified Newtonian dynamics
G. Gentile, G. W. Angus, B. Famaey +2
Within the framework of modified Newtonian dynamics (MOND) we investigate the kinematics of two dwarf spiral galaxies belonging to very different environments, namely KK 246 in the…
Radial Migration Does Little for Galactic Disc Thickening
I. Minchev, B. Famaey, A. C. Quillen +3
Non-axisymmetric components, such as spirals and central bars, play a major role in shaping galactic discs. An important aspect of the disc secular evolution driven by these pertur…
