Abstract
We have developed an axisymmetric model for the dust envelope of the carbon star RW LMi with a density distribution typical for the superwind stage using JHKLM photometric data obtained in 1997–2003, supplemented by flux data at optical, mid-IR, and far-IR wavelengths. In contrast to earlier spherically-symmetric models, the model is able to reproduce the observed fluxes in all observed wavelength ranges, and provides a good agreement with the observational data. The estimated mass-loss rate is \(\dot M = 1.2 \times 10^{ - 5} M_ \odot /yr\). The computed brightness distribution of the envelope in the near-IR is in satisfactory agreement with high-resolution observations, while the optical size is considerably larger than is observed.
