▪ Abstract In this contribution, a review is presented on the ample data obtained on post-AGB
stars, both on the central stars and their circumstellar material. The fast evolutionary phase is …

▪ Abstract Absolute magnitudes are estimated for carbon stars of various subtypes in the
Hipparcos catalogue and as found in the Magellanic Clouds. Stellar radii fall within the limits …

Wave–particle duality, as manifest in the two-slit experiment, provides perhaps the most
vivid illustration of Bohr's complementarity principle: wave-like behaviour (interference) …

We have constructed three-dimensional smoothed particle hydrodynamics models to
examine the influence of a detached binary companion on the dusty winds from red giants …

Aims. We aim at showing that the broad-band SED characteristics of our sample of post-AGB
stars are best interpreted, assuming the circumstellar dust is stored in Keplerian rotating …

Abstract The Red Rectangle is the prototype of a class of carbon-rich reflection nebulae
surrounding low-mass stars in the final stages of evolution. The central star of this nebula …

We discuss the interaction of the slow wind blown by an asymptotic giant branch (AGB) star
with a collimated fast wind (CFW) blown by its main-sequence or white dwarf companion, at …

This is the first paper in a series of three where we present the first comprehensive inventory
of solid state emission bands observed in a sample of 17 oxygen-rich circumstellar dust …

Abstract We present Hubble Space Telescope (HST) Wide Field Planetary Camera 2 and
deep ground-based images of the Red Rectangle (RR), a bipolar proto–planetary nebula …

We report the discovery of the rotational spectrum of CH+ in the Infrared Space Observatory
Long Wavelength Spectrometer (LWS) spectrum of the planetary nebula NGC 7027. The …
