We report the preliminary near- and mid-infrared 3D radiative transfer simulations of the carbon-rich AGB star RUVir 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 RUVir’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.

我们使用 3D 辐射传输代码 RADMC-3D 报告了富碳 AGB 恒星 RUVir 的初步近红外和中红外 3D 辐射传输模拟。我们发现，分子和尘埃物种的包含很好地再现了这颗恒星的扩展大气。这项研究是对 RUVir 的扩展大气和其他 AGB 恒星进行更系统的 3D 辐射传输建模的努力的开始。这些努力旨在限制恒星的恒星参数，并作为使用最新的 VLTI/MATISSE 干涉仪对富碳 AGB 恒星进行首次多波长成像的准备工作。
