Beyond the asymptotic giant branch [PDF]
, 2008 The evolution of the IR spectra of asymptotic giant branch (AGB) stars has been obtained by time-dependent radiative transfer models. These models are compared with IRAS photometric and spectroscopic observations. Extrapolation of the models to beyond the AGB lead to predictions of the spectra of proto-planetary nebulae.

Evolution on the Asymptotic Giant Branch
2012Stars of low and intermediate mass experience recurrent thermal instabilities during the phase of double (hydrogen and helium) shell burning. During this phase they populate the Asymptotic Giant Branch. The thermal instabilities give rise to drastic, but short-lived structure variations, mixing episodes and specific phases of nucleosynthesis.

Nucleosynthesis in asymptotic giant branch stars
AIP Conference Proceedings, 2014The nucleosynthesis in asymptotic giant branch stars (briefly: AGB)is a challenging and fascinating subject in the theory of stellar evolution and important for observations as well. This is because about of half the heavy elements beyond iron are synthesized during thermal pulsation phases of these stars.

Asymptotic giant branch stars in the ISOGAL survey
2000We present and analyse the data of a field at 1 = 0o, b = +1o from the ISOGAL survey of selected areas of the inner Galactic bulge at 15 and 7 ?m. In combination with IJKs data from the near-infrared southern sky survey DENIS, the ISOCAM data allow the first detailed study of infrared stellar populations in very obscured regions of the inner Galaxy ...
