A second post-AGB nebula that contains gas in rotation and in expansion: ALMA maps of IW Car
V. Bujarrabal, A. Castro-Carrizo, H. Van Winckel +2
We aim to study the presence of both rotation and expansion in post-AGB nebulae, in particular around IW Car, a binary post-AGB star that was suspected to be surrounded by a Kepler…
ALMA high spatial resolution observations of the dense molecular region of NGC 6302
M. Santander-García, V. Bujarrabal, J. Alcolea +5
The mechanism behind the shaping of bipolar planetary nebulae is still poorly understood. Accurately tracing the molecule-rich equatorial regions of post-AGB stars can give valuabl…
The millimeter IRAM-30m line survey toward IK Tau
L. Velilla Prieto, C. Sánchez Contreras, J. Cernicharo +8
We carried out a millimeter wavelength line survey between 79 and 356 GHz with the IRAM-30m telescope to investigate the physical and chemical properties of the molecular envelope…
Further ALMA observations and detailed modeling of the Red Rectangle
V. Bujarrabal, A. Castro-Carrizo, J. Alcolea +3
We present new high-quality ALMA observations of the Red Rectangle (a well known post-AGB object) in C17O J=6-5 and H13CN J=4-3 line emission and results from a new reduction of al…
A lambda 3mm and 1mm line survey toward the yellow hypergiant IRC +10420
G. Quintana-Lacaci, M. Agúndez, J. Cernicharo +4
Our knowledge of the chemical properties of the circumstellar ejecta of the most massive evolved stars is particularly poor. We aim to study the chemical characteristics of the pro…
Imaging the dust sublimation front of a circumbinary disk
M. Hillen, J. Kluska, J. -B. Le Bouquin +4
We present the first near-IR milli-arcsecond-scale image of a post-AGB binary that is surrounded by hot circumbinary dust. A very rich interferometric data set in six spectral chan…
