Study of the light curve of old classical novae: The long term photometric behaviour of all known classical novae (in collaboration with German, American and Chilean collaborators).

Photometry with high temporal resolution of novae near maximum light.

Investigation of the nature of Symbiotic stars: Optical and UV photometry and spectroscopy of Symbiotic stars.

The WET project: The Wise Observatory is taking an active part in the international network of optical observatories entitled the Whole Earth Telescope. A group of observatories, extending over 6 continents, are observing together for about 10 or more days one and the same astronomical object. The distribution of the observing station around Earth, enables a continuous photometric monitoring of the target object for the entire duration of such a long period of time. The "temporal spectroscopy" of variable stars provides observational data on masses and on the internal structure of stars that have no parallel in any other mode of astronomical observations.
