Unveiling the dust nucleation zone of IRC+10216 with ALMA
J. Cernicharo, F. Daniel, A. Castro-Carrizo +5
We report the detection in IRC+10216 of lines of HNC =3-2 pertaining to 9 excited vibrational states with energies up to 5300 K. The spectrum, observed with ALMA, also sho…
ALMA observations of the Red Rectangle, a preliminary analysis
V. Bujarrabal, A. Castro-Carrizo, J. Alcolea +5
We aim to study equatorial disks in rotation and axial outflows in post-AGB objects, as to disclose the formation and shaping mechanisms in planetary nebulae. So far, both disks an…
Extended rotating disks around post-AGB stars
V. Bujarrabal, J. Alcolea, H. Van Winckel +2
There is a group of binary post-AGB stars that show a conspicuous NIR excess, usually assumed to arise from hot dust in very compact possibly rotating disks. These stars are surrou…
