Imaging the circumstellar envelopes of AGB stars

Astronomy and Astrophysics, 2006
We report the results of an exploratory program to image the extended circumstellar envelopes of asymptotic giant branch (AGB) stars in dust-scattered galactic light. The goal is to characterize the morphology of the envelopes as a probe of the mass-loss

Unveiling the Circumstellar Envelope and Disk: A Sub-Arcsecond Survey of Circumstellar Structures [PDF]

The Astrophysical Journal, 1999
We present the results of a 2.7 mm continuum interferometric survey of 24 young stellar objects in 11 fields. The target objects range from deeply embedded Class 0 sources to optical T Tauri sources.

A search for diffuse bands in the circumstellar envelopes of post-AGB stars [PDF]

, 2007
In this work we present the results of a systematic search for diffuse bands (DBs, hereafter) in the circumstellar envelopes of a carefully selected sample of post-AGB stars.

n-Alkanes formed by methyl-methylene addition as a source of meteoritic aliphatics [PDF]

Communications Chemistry
Aliphatics prevail in asteroids, comets, meteorites and other bodies in our solar system. They are also found in the interstellar and circumstellar media both in gas-phase and in dust grains.

CO line emission from circumstellar envelopes [PDF]

Astronomy & Astrophysics, 2006
Aims. We present the results of a multi-transition CO observational program conducted on a sample of AGB and post-AGB stars envelopes. We have collected maps and single pointing observations of these envelopes in 5 rotational transitions ranging from J = 1–0 to J = 6–5, including in particular new observations of the CO line at 691 GHz at the CSO.
