The evolved stars of Leo II dSph galaxy from near-infrared UKIRT/WFCAM observations
M. Gullieuszik, E. V. Held, L. Rizzi +3
We present a study of the evolved stellar populations in the dwarf spheroidal galaxy LeoII, based on JHKs observations obtained with the near-infrared array WFCAM at the UKIRT tele…
Scaled solar tracks and isochrones in a large region of the Z-Y plane I. From the ZAMS to the TP-AGB end for 0.15 - 2.5 Mo stars
G. Bertelli, L. Girardi, P. Marigo +1
Tracks and isochrones have been computed in the range of initial masses 0.15 - 20 Mo for a grid of 39 chemical compositions with the metal content Z between 0.0001 and 0.070, and h…
Evolution of asymptotic giant branch stars II. Optical to far-infrared isochrones with improved TP-AGB models
Paola Marigo, Leo Girardi, Alessandro Bressan +3
We present a large set of theoretical isochrones, whose distinctive features mostly reside on the greatly improved treatment of the thermally pulsing asymptotic giant branch (TP-AG…
Evolution of asymptotic giant branch stars I. Updated synthetic TP-AGB models and their basic calibration
Paola Marigo, Leo Girardi
We present new synthetic models of the TP-AGB evolution. They are computed for 7 values of initial metal content (Z from 0.0001 to 0.03) and for initial masses between 0.5 and 5.0…
Can the third dredge-up extinguish hot-bottom burning in massive AGB stars?
Paola Marigo
Marigo (2002) has highlighted the crucial importance of molecular opacities in modelling the evolution of AGB stars at varying surface C/O ratio. In particular, it has been shown t…
Population synthesis models including AGB stars and their ingredients
Paola Marigo
I will briefly review the state of the art of evolutionary population synthesis (EPS) models that include the contribution from AGB stars.
