. Discovered initially by SkyMapper, SMSS J031300.36-670839.3, is a sub-giant halo star, found from a high resolution blue MIKE spectrum to have an undetectable Fe abundance and overabundances of C, Mg, and Ca, relative to Fe. We recently obtained 29 UVES spectra extending to 3060 Angstroms which has enabled us to measure the oxygen abundance from the OH lines, and lower the 1D, LTE Fe abundance limit to [Fe/H] .

... By means of deep optical images obtained at the Special Astrophysical Observatory 6-m telescope it was discovered that some Seyfert galaxies that were earlier considered to be non-interacting objects displayed signatures of elongated tidal envelopes belonging to satellite debris. ... Our results suggest that statistic studies based on popular imaging surveys (for example SDSS) can lead to an underestimation of the fraction of minor mergers among galaxies with active nuclei (AGN). ...

My research efforts have focused on three areas which are: . More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to the reflex motions of their host stars, and more recently through transits of some planets across the face of the host stars. ... Gravitational microlensing provides a novel technique to look for planets around lens stars, and this is the only technique currently capable of detecting Earth-mass planets. ...

... Cosmic Vacuum . Recent observational studies of remote supernovae have suggested the existence of cosmic vacuum with the density which is larger than the total density of all the other forms of cosmic energy in the Universe. Vacuum produces the field of anti-gravity and induces acceleration of the cosmological expansion. ...
