Resolving asymmetries along the pulsation cycle of the Mira star X Hya
X. Haubois, M. Wittkowski, G. Perrin +6
The mass-loss process in Mira stars probably occurs in an asymmetric way where dust can form in inhomogeneous circumstellar molecular clumps. Following asymmetries along the pulsat…
Resolving the stellar activity of the Mira AB binary with ALMA
W. H. T. Vlemmings, S. Ramstedt, E. O'Gorman +4
We present the size, shape and flux densities at millimeter continuum wavelengths, based on ALMA science verification observations in Band 3 (~94.6 GHz) and Band 6 (~228.7 GHz), fr…
Dissecting the AGB star L2 Puppis: a torus in the making
F. Lykou, D. Klotz, C. Paladini +11
The circumstellar environment of L2 Pup, an oxygen-rich semiregular variable, was observed to understand the evolution of mass loss and the shaping of ejecta in the late stages of…
From the atmosphere to the circumstellar environment in cool evolved stars
Markus Wittkowski, Claudia Paladini
We discuss and illustrate contributions that optical interferometry has made on our current understanding of cool evolved stars. We include red giant branch (RGB) stars, asymptotic…
What causes the large extensions of red-supergiant atmospheres? Comparisons of interferometric observations with 1-D hydrostatic, 3-D convection, and 1-D pulsating model atmospheres
B. Arroyo-Torres, M. Wittkowski, A. Chiavassa +6
We present the atmospheric structure and the fundamental parameters of three red supergiants, increasing the sample of RSGs observed by near-infrared spectro-interferometry. Additi…
