Hartmann, L. ; Apruzese, J. P. Abstract A consistent picture explaining both the spectral and photometric (infrared and visual) variations of R Coronae Borealis is developed. It is found that the extreme infrared maximum and minimum can be fitted by dispersion of the same mass of graphite dust. Random clumps of this dust crossing the line of sight both obscure the visual continuum of the object and reveal an emission spectrum from a circumstellar gas cloud, which satisfactorily accounts for the correlation of the emission with episodes of a faint visual continuum.
