Universidad de Granada.<br /><br />Abstract: </p><p>The Asymptotic Giant Branch stars, in particular those of carbon types,<br />are excellent laboratories to constraint the theory of structure,<br />evolution and nucleosynthesis of low mass stars. Despite the uncertainties<br />still existing in the chemical analysis of these stars,<br />the determination of the abundances of several key speciesin their<br />atmospheres (lithium, carbon, fluorine and s-elements etc..) is an useful<br />tool to test these theories and the mixing processes occurring inside<br />these stars. I will briefly review recent advances on this subject.</p><p> </p><p>Place and time:</p><p> Physics Depertment meetign room, 2nd floor</p><p>2 June 2010, 11:00 </p>
