DESCRIPTION:Adrian Fraser\, Astrophysical and Planetary Sciences\, Universi
 ty of Colorado Boulder\n\nMagnetic Instabilities in rapidly rotating\, sta
 bly stratified cylinders\n\nAs stars evolve beyond their core-hydrogen-bur
 ning phase\, angular momentum conservation suggests their contracting core
 s should spin up and their expanding envelopes should spin down. However\,
  observations show a much smaller core-envelope rotation difference than e
 xpected\, indicating some angular momentum transport in the stably stratif
 ied region between the core and envelope. One proposed source of transport
  is MHD turbulence driven by the Tayler instability\, which combines with 
 differential rotation to form the Tayler-Spruit dynamo (TSD). However\, th
 e extreme parameter regimes relevant to stellar interiors have confounded 
 efforts to probe the properties of the TSD directly via numerical simulati
 ons. In this talk\, I will discuss this issue and present preliminary resu
 lts towards studying this system in rapidly rotation\, stably stratified r
 egimes.
