| Abstract: | We present the results of JHKLM-photometry for the symbiotic Mira star candidate V 335 Vul. Based on the average flux data, supplemented by IRAS, MSX, AKARI, and WISE mid-IR observations, we calculated a model of a spherically symmetric dust envelope of the star, made up of amorphous carbon and silicon carbide particles. The optical depth of the envelope in the visible range with a dust temperature at the inner boundary of T1 = 1300 K is τ V = 0.58. For an envelope expansion velocity of 26.5 km s?1, the estimated mass loss rate is equal to 5.7 × 10?7M⊙ yr?1. |
