SUMMARY:Kinematics and stellar populations in the outer halos of early type
  galaxies
DESCRIPTION:Kinematics and stellar populations in the outer halos of early 
 type galaxies\nDr. Lodovico Coccato\n\nStellar halos of galaxies offer an 
 important laboratory to understand the galaxies’ formation process a
 nd evolution. In fact, the dynamic time scale in the halos are large, and 
 the imprint of the formation mechanisms may still be preserved at large ra
 dii in the kinematics, in the orbital structure, in streams and substructu
 res, or in the chemical composition and distribution of stars.  I will dis
 cuss i) the kinematic and dynamical properties of stellar halos in early t
 ype galaxies as derived from tracers like planetary nebulae and globular c
 lusters; and ii) the stellar population properties as derived from deep lo
 ng-slit spectra in a number of massive ellipticals. Results are then discu
 ssed in the framework of galaxy halo formation mechanisms.
