Sažetak
We present a study of the properties of circumstellar dust in symbiotic Miras during sufficiently long time intervals, including observed obscuration events. The published JHKL magnitudes of o Ceti, RX Pup, KM Vel, V366 Car, V835 Cen, HM Sge, V1016 Cyg, RR Tel, V407 Cyg, R Aqr have been collected. In order to follow the evolution of their colours in time, we removed the Mira pulsations to correct their light curves. Assuming spherical distribution of the dust in the close neighbourhood of the Mira, the DUSTY code was used to solve the radiative transfer in order to determine the dust temperature and its properties in each particular case. The preliminary results of this first systematic study of dust envelopes in symbiotic stars with Miras as cool components provide information on common nature of dust in these objects.
