Journal ArticleDOI
The structure of the Milky Way's bar outside the bulge
TL;DR: In this paper, the authors investigated the long bar of the Milky Way using red clump giant (RCG) stars from UKIDSS, 2MASS, VVV, and GLIMPSE.
Journal ArticleDOI
Dynamical modelling of the galactic bulge and bar: the Milky Way's pattern speed, stellar and dark matter mass distribution
TL;DR: In this paper, a large set of dynamical models of the galactic bulge, bar and inner disk using the made-to-measure method was constructed to match the red clump giant density from a combination of the VVV, UKIDSS and 2MASS infrared surveys.
Journal ArticleDOI
Made-to-measure models of the Galactic box/peanut bulge: stellar and total mass in the bulge region
Matthieu Portail,Christopher Wegg,Ortwin Gerhard,Inma Martinez-Valpuesta,Inma Martinez-Valpuesta +4 more
TL;DR: In this paper, the authors construct dynamical models of the Milky Way's Box/Peanut (B/P) bulge, using the recently measured 3D density of Red Clump Giants (RCGs) as well as kinematic data from the BRAVA survey.
Journal ArticleDOI
Peanuts, brezels and bananas: food for thought on the orbital structure of the Galactic bulge
TL;DR: In this article, a set of N-body models where the peanut bulge is mainly supported by brezel-like orbits is presented, allowing strong peanuts to form with short extent relative to the bar length.
Journal ArticleDOI
Revisiting the Tale of Hercules: How Stars Orbiting the Lagrange Points Visit the Sun
TL;DR: In this paper, a made-to-measure dynamical model tailored for the Milky Way to investigate the kinematics of the solar neighborhood (SNd) was proposed.
