CO observations in rotating circumbinary post-AGB disks
I. Gallardo Cava, J. Alcolea, H. Van Winckel +3
There is a group of post-AGB stars that are part of a binary system and that show a significant NIR excess. These systems are known to host disks with Keplerian or quasi-Keplerian…
Continuum and molecular emission from the inner regions of the symbiotic system R Aquarii
M. Gómez-Garrido, V. Bujarrabal, J. Alcolea +3
Symbiotic systems often include an asymptotic giant branch (AGB) star and a hot compact companion, such as a white dwarf, that are in close interaction. Due to the intense ultravio…
The nebula around the binary post-AGB star 89 Herculis
I. Gallardo Cava, J. Alcolea, V. Bujarrabal +2
There is a class of binary post-asymptotic giant branch (post-AGB) stars that exhibit remarkable near-infrared (NIR) excess. These stars are surrounded by disks with Keplerian or q…
Chemistry of nebulae around binary post-AGB stars: A molecular survey of mm-wave lines
I. Gallardo Cava, V. Bujarrabal, J. Alcolea +2
Context. There is a class of binary post-asymptotic giant branch (post-AGB) stars that exhibit remarkable near-infrared (NIR) excess. Such stars are surrounded by Keplerian or quas…
Ultra-deep 31.0-50.3 GHz spectral survey of IRC+10216
J. R. Pardo, J. Cernicharo, B. Tercero +8
Context. IRC+10216, the carbon-rich envelope of the asymptotic giant branch (AGB) star CW Leo, is one of the richest molecular sources in the sky. Available spectral surveys below…
Keplerian disks and outflows in post-AGB stars: AC Herculis, 89 Herculis, IRAS 19125+0343, and R Scuti
I. Gallardo Cava, M. Gómez-Garrido, V. Bujarrabal +3
There is a class of binary post-AGB stars with a remarkable near-infrared excess that are surrounded by Keplerian or quasi-Keplerian disks and extended outflows composed of gas esc…
Circumstellar envelopes of semi-regular long-period variables: mass-loss rate estimates and general model-fitting of the molecular gas
J. J. Díaz-Luis, J. Alcolea, V. Bujarrabal +4
We aim to study the main properties of a volume-limited unbiased sample of well-characterized semi-regular variables (SRs) in order to clarify important issues, such as the formati…
