The Enigma of Lithium: from CP Stars to K Giants. First Results of CP Star Observations Obtained at Mount Stromlo Observatory
N. S. Polosukhina, N. A. Drake, M. Hack +3
We present the results of the observations of some roAp stars made at Mount Stromlo Observatory during 17 nights in 2001 September-October. This long observing run permitted us to…
Near-infrared and Br_gamma observations of post-AGB stars
G. C. Van de Steene, P. A. M. van Hoof, P. R. Wood
We investigate the infrared properties of the IRAS sources not confirmed as PNe in Van de Steene & Pottasch (1993). We observed 28 objects in the N-band of which 20 were detected a…
Degenerate thermal pulses in AGB stars
Cheryl Frost, John Lattanzio, Peter Wood
We report on the discovery of a new kind of thermal pulse in intermediate mass AGB stars. Deep dredge-up during normal thermal pulses on the AGB leads to the formation of a long, u…
The Brightest Carbon Stars
Cheryl Frost, Robert Cannon, John Lattanzio +2
It is currently accepted that Hot-Bottom-Burning (HBB) in intermediate-mass asymptotic giant branch (AGB) stars prevents the formation of C~stars. Nevertheless, we present in this…
