Dynamics of the Milky Way Bar/Bulge

Proceedings of the International Astronomical Union, 2019
AbstractStellar surveys and dynamical models have recently led to important progress on understanding the dynamical structure of the Milky Way’s bar and central box/peanut bulge. This talk briefly reviews the density structure of the bulge and bar from star count tomography, the cylindrical rotation of bulge stars, and the measurements of their stellar

Rotation and Dynamics of the Milky Way Galaxy

2020
When Oort returned to Leiden, his parents were in the Dutch East Indies for a year. Already on September 1, the day after his arrival, Oort was introduced to the staff at the Sterrewacht and started his appointment. His old study friend from Groningen, Jan Schilt, also worked in Leiden.

The Structure and Dynamics of the Milky Way Galaxy

2002
Now that we have become familiar with the stars, their properties and their motions, and also with the various components of the interstellar medium, we have collected all the “parts” we need in order to consider our Milky Way galaxy. We begin in Sect. 11.1 with the information about the structure of the Milky Way which can be gained from observations ...

Chemo-dynamical simulations of the Milky Way

Using a state of the art galaxy formation software package, GCD+, we model the formation and evolution of galaxies which resemble our own Galaxy, the Milky Way. The simulations include gravity, gas dynamics, radiative gas cooling, star formation and stellar evolution, tracing the production of several elements and the subsequent pollution of the ...

Stellar populations and dynamics in the Milky Way galaxy

2001
Our Galaxy offers a unique opportunity to deduce the important physics involved in galaxy formation from observations of those old stars that were formed at the time of the formation of the Milky Way, and whose present properties contain some fossil record of the Galaxy’s history.

Dynamics of Disrupting Milky Way Satellite Galaxies and Tidal Streams

AIP Conference Proceedings, 2005
The nature of the Galactic dSph satellites remains controversial. Do they have extreme M/L? Are they tidally disrupting? Do they contribute significantly to the creation of the halo and halo substructure? Does mass follow light in these Systems? Great insight into these questions will come from high quality radial velocity surveys over large areas ...
