Milky Way Mass Models for Orbit Calculations

Understand

Studying the trajectories of objects like stars, globular clusters or satellite galaxies in the Milky Way allows to trace the dark matter halo but requires reliable models of its gravitational potential.

• Realistic, yet simple and fully analytical models have already been presented in the past.
• However, improved as well as new observational constraints have become available in the meantime calling for a recalibration of the respective model parameters.
• Three widely used model potentials are revisited.
