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…
Circumstellar envelopes of semi-regular long-period variables: mass-loss rate estimates and general model-fitting of the molecular gas
J. J. Díaz-Luis, J. Alcolea, V. Bujarrabal +4
We aim to study the main properties of a volume-limited unbiased sample of well-characterized semi-regular variables (SRs) in order to clarify important issues, such as the formati…
Resolving discrepancy in the pPN OH231.8+4.2
J. -F. Desmurs, J. Alcolea, M. Lindqvist +3
OH231.8+4.2 is an archetypal pre-planetary nebulae (pPN). It is a binary system surrounded by bipolar nebula. Some years ago the authors extensively studied it and performed severa…
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…
Missing flux in VLBI observations of SiO maser at 7mm in IRC+10011
J. -F. Desmurs, J. Alcolea, V. Bujarrabal +2
VLBI observations of SiO masers recover at most 40-50% of the total flux obtained by single dish observations at any spectral channel. Some previous studies seems to indicate that,…
The Spanish Square Kilometre Array White Book
J. A. Acosta-Pulido, I. Agudo, A. Alberdi +116
The Square Kilometre Array (SKA) is called to revolutionise essentially all areas of Astrophysics. With a collecting area of about a square kilometre, the SKA will be a transformat…
