Context. The stellar metallicity gradients of disc galaxies provide information on disc assembly, star formation processes, and chemical evolution. They also might store information on dynamical processes that could affect ...

We have classified orbits in a stationary triaxial stellar system created from a cold dissipationless collapse of 100,000 particles. In order to integrate the orbits, two potential approximations with different fitting ...

he Theory Group at the Departamento de Astronom ıa at the Universidad de Concepci on will organise the MODEST 15 conference, which will be held in Concepci on, Chile at the 2nd - 6th of March 2015. This will be the 15th ...

The origin of ultracompact dwarf (UCD) galaxies, compact extragalactic stellar systems, is still a puzzle for present galaxy formation models. We present the comprehensive analysis of high resolution multi-object spectroscopic ...
