Silicate condensation in Mira variables
Hans-Peter Gail, Michael Scholz, Annemarie Pucci
We study whether the condensation of silicate dust in Mira envelopes could be caused by cluster formation by the abundant SiO molecules. For a simplified model of the pulsational m…
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…
Effects of moderate abundance changes on the atmospheric structure and colours of Mira variables (Research Note)
Michael Scholz, Michael J. Ireland, Peter R. Wood
Aims. We study the effects of moderate deviations from solar abundances upon the atmospheric structure and colours of typical Mira variables. Methods. We present two model series o…
New insights into the dust formation of oxygen-rich AGB stars
I. Karovicova, M. Wittkowski, K. Ohnaka +3
We observed the AGB stars S Ori, GX Mon and R Cnc with the MIDI instrument at the VLTI. We compared the data to radiative transfer models of the dust shells, where the central stel…
Dynamical Opacity-Sampling Models of Mira Variables. II: Time-Dependent Atmospheric Structure and Observable Properties of 4 M-Type Model Series
Michael J. Ireland, Michael Scholz, Peter R. Wood
We present 4 model series of the CODEX dynamical opacity-sampling models of Mira variables with solar abundances, designed to have parameters similar to Cet, R Leo and R Cas. W…
Mid-infrared interferometric monitoring of evolved stars - The dust shell around the Mira variable RR Aql at 13 epochs
I. Karovicova, M. Wittkowski, D. A. Boboltz +3
We obtained 13 epochs of mid-infrared interferometry with the MIDI instrument at the VLTI between April 2004 and July 2007, covering pulsation phases 0.45-0.85 within four cycles.…
