TP-AGB stars with envelope burning
In this paper we focus on the TP-AGB evolution of intermediate-mass stars experiencing envelope burning (M = 4÷5M⊙). Our model of the TP-AGB phase is suitably designed to follow the peculiar behaviour of these stars, to which the simple analytical treatment valid in the low-mass range can no longer be applied. The approach we have adopted is a semi-analytical one as it combines analytical relat...
متن کاملA C - Band Spectral Scan of Irc + 10 216
We report the results of the presently lowest frequency spectral line survey of the asymptotic giant branch carbon star IRC+10 216. The entire Arecibo C band (4–6 GHz) was observed with a noise level of 0.3 mJy (1 ). We report the detection of HC5N (J 1⁄4 2 1), which is the lowest frequency transition of the HC5N molecule found in the envelope of IRC +10 216. The HC5N J 1⁄4 2 column density der...
متن کاملIRC + 10 216 revisited II . The circumstellar CO shell ?
12 CO and 13 CO J = 6-5 observations of IRC +10 216 with the JCMT are presented. A spherically symmetric radia-tive transfer code is used to model these and other CO observations of the carbon star IRC +10 216/CW Leo. Compared to previously published model calculations a much larger set of observational data is used as constraints; on-source 12 CO and 13 CO J = 1-0 up to J = 6-5 and mapping dat...
متن کاملCS 30322 - 023 : an ultra metal - poor TP - AGB star ? ⋆
Context. The remarkable properties of CS 30322-023 became apparent during the course of a high-resolution spectroscopic study of a sample of 23 carbon-enhanced, metal-poor (CEMP) stars. Aims. This sample is studied in order to gain a better understanding of sand r-process nucleosynthesis at low metallicity, and to investigate the role of duplicity. Methods. High-resolution UVES spectra have bee...
متن کاملThe dynamical evolution of the fragmented , bipolar dust shell around the carbon star IRC + 10 216 ⋆ Rapid changes of a PPN - like structure ?
We present high–resolution J–, H–, and K–band observations and the first H − K color image of the carbon star IRC +10 216. The images were reconstructed from 6 m telescope speckle interferograms using the bispectrum speckle interferometry method. The H and K images with resolutions between 70 mas and 92 mas consist of several compact components within a 0. ′′2 radius and a fainter asymmetric ne...
