"Stars and stellar evolution"
ALMA has been producing stunning images and results for stars acrossthe mass and evolutionary ranges. In this talk, I will focus on someresults for Asymptotic Giant Branch Stars (AGB), Planetary Nebulae, RedSupergiants (RSG) and Supernovae. An area of particular interest is theshaping process by which AGB stars evolve to form often highly axisymmetricPlanetary Nebulae - what are the roles of binarity and magnetic fields? Aswell as the mechanisms by which some of the stars are losing large amountsof mass (10-7 to 10-4 Msun/yr) to the interstellar medium. Finally I willdiscuss how ALMA long baseline and high frequency data are starting tohelp answer some of the long-standing questions in stellar evolution.
