SUMMARY:Physical Manifestations of Evolution\, Regularity and Chaos In and
  Around Our Galaxy - Kathryn Johnston (Columbia University)
DTSTART:20170309T160000Z

UID:TALK70216@talks.cam.ac.uk
CONTACT:Simon Hodgkin
DESCRIPTION:Our Galaxy is thought to be dynamically young with a fairly sm
 ooth potential\ndominated by a nearly spherical dark matter halo that has 
 evolved little in\nthe last several billion years. These attributes broadl
 y suggest that\npotential evolution and dynamical chaos should have neglig
 ible influences on\nthe orbits of its constituent stars\, as well as on th
 e stellar structures\nthey collectively support. This talk reviews some re
 cent results which point\nto signatures of Galactic evolution and the chao
 tic nature of stellar orbits\nthat can be (and have been) observed.
