Structure and dynamics of the inner nebula around the symbiotic stellar system R Aqr
V. Bujarrabal, M. Agundez, M. Gomez-Garrido +5
We investigate the structure, dynamics, and chemistry of the molecule-rich nebula around the stellar symbiotic system R Aqr, which is significantly affected by the presence of a wh…
Very fast variations of SiO maser emission in evolved stars
Miguel Gómez-Garrido, Valentín Bujarrabal, Javier Alcolea +3
Context. Stars on the asymptotic giant branch (AGB) are long-period variables that present strong flux variations at almost all wavelengths, including the SiO maser lines. The peri…
Interferometric observations of SiO thermal emission in the inner wind of M-type AGB stars IK Tauri and IRC+10011
J. L. Verbena, V. Bujarrabal, J. Alcolea +2
Context. AGB stars go through a process of strong mass-loss that involves pulsations of the atmosphere, which extends to a region where the conditions are adequate for dust grains…
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…
