... Of the fundamental properties that determine the state of a star (mass, composition and age, primarily), we can directly and accurately measure many stars' masses and then estimate the mass of a single star of the same spectral types. ...
... We model the spectral energy distributions using radiative transfer codes and find that these three stars have mass-loss rates up to 10-3 M_тКЩ yr-1, suggesting that high-mass stars are important contributors to the life-cycle of dust. ...
