Symbiotic stars are interacting binary systems composed of an evolved star (generally a late-type red giant) and a degenerate or dwarf companion in orbit close enough for mass transfer to occur. Understanding the status of the late-type star is impor

Some types of variable stars often show long-term variations superimposed on the dominant short-period changes in brightness. Removal of the short-term component is crucial if we are interested to study the long-term variations. We propose Phase Dist

Circumstellar dust in symbiotic Miras plays a key role in driving stellar outflow and mass transfer that can lead to nova outbursts. We have studied dust properties and mass loss rates in 14 symbiotic Miras, including five symbiotic novae, by use of

We present a model of inner dust regions around the cool Mira component of the two symbiotic novae, RR Tel and HM Sge, based on the near-IR photometry, ISO spectra and mid-IR interferometry. The dust properties were determined using the DUSTY code. A
