... Adopting the HIPPARCOS parallax we derived from the 1045 nm-observation a photospheric radius (Rosseland Ross = 1 radius) of R Leo of 417 R ? 97 R (19.2 mas ? 2.0 mas) indicating pulsation in the first-overtone mode. ... The closest E model with phase 1.21 has an effective temperature of 2610 K. Application of its CLV and mbol = 0.24 ? 0.20 (measured at phase 0.20) to our 1045/9 observation yields for R Leo an angular Rosseland radius of 19.1 mas ? 2.0 mas and an K.-H. Hofmann et al.: ...

Schematic view of the central star, an obscuring dust cloud, and an optically thin dust shell. ... Simultaneous fits of the models to the observed SED and visibility have demonstrated that a model with the central star and an optically thin dust shell with density proportional to r-2 seems to be appropriate for R CrB near maximum light. ...
