The first "water fountain" collimated outflow in a planetary nebula
J. F. Gomez, O. Suarez, Ph. Bendjoya +8
"Water fountains" (WFs) are evolved objects showing high-velocity, collimated jets traced by water maser emission. Most of them are in the post-Asymptotic Giant Branch and they may…
ALMA sub-mm maser and dust distribution of VY Canis Majoris
A. M. S. Richards, C. M. V. Impellizzeri, E. M. Humphreys +25
Cool, evolved stars have copious, enriched winds. The structure of these winds and the way they are accelerated is not well known. We need to improve our understanding by studying…
HO maser emission associated with the planetary nebula IRAS 163334807
L. Uscanga, J. F. Gómez, L. F. Miranda +5
We present simultaneous observations of HO maser emission and radio continuum at 1.3 cm carried out with the Australia Telescope Compact Array towards two sources, IRAS 16333$-…
Modelling the 3D morphology and proper motions of the planetary nebula NGC 6302
L. Uscanga, P. F. Velázquez, A. Esquivel +3
We present 3D hydrodynamical simulations of an isotropic fast wind interacting with a previously ejected toroidally-shaped slow wind in order to model both the observed morphology…
A sensitive search for methanol line emission toward evolved stars
J. F. Gomez, L. Uscanga, O. Suarez +2
We present a sensitive search for methanol line emission in evolved stars at 1 cm, aiming to detect, for the first time, methanol masers in this type of objects. Our sample compris…
