3D Radiative Transfer Simulations of the Atmospheric Environment of the Carbon-rich AGB Star RU Vir.

RAU G.

Abstract (from CDS):

We report the preliminary near- and mid-infrared 3D radiative transfer simulations of the carbon-rich AGB star RU Vir using the 3D radiative transfer code RADMC-3D. We found that the inclusion of molecular and dust species reproduces the extended atmosphere of this star well. This study is the beginning of an in-progress effort toward a more systematic 3D radiative transfer modeling of RU Vir's extended atmosphere, and other AGB stars. These efforts aim at constraining the stars' stellar parameters, and as preparatory work for the first multi-wavelength imaging of carbon-rich AGB stars with the newest VLTI/MATISSE interferometric instrument.
