On the circumstellar envelopes of semi-regular long-period variables
J. J. Díaz-Luis, J. Alcolea, V. Bujarrabal +3
The mass loss process along the AGB phase is crucial for the formation of circumstellar envelopes (CSEs), which in the post-AGB phase will evolve into planetary nebulae (PNe). Ther…

Through the magnifying glass: ALMA acute viewing of the intricate nebular architecture of OH231.8+4.2
C. Sánchez Contreras, J. Alcolea, A. Castro-Carrizo +4
We present continuum and molecular line emission ALMA observations of OH 231.8+4.2, a well studied bipolar nebula around an asymptotic giant branch (AGB) star. The high angular res…

The maser emitting structure and time variability of the SiS lines J=14-13 and 15-14 in IRC+10216
J. P. Fonfría, M. Fernández-López, J. R. Pardo +8
We present new high angular resolution interferometer observations of the v=0 J=14-13 and 15-14 SiS lines towards IRC+10216, carried out with CARMA and ALMA. The maps, with angular…
