Orbital motion of three very young multiple stars within the Orion Trapezium

Observations of the bipolar nebula AFGL2688 on a 6m telescope with a record spectral resolution resulted in separating details of a photosphere origin from details of a circumstellar origin with velocities pertinent to the observable stage and to the previous stage of evolution of the object. For the first time a transition from a carbon stage star to a post-AGB star, the inner layers of which passed through a CN-cycle, has been registered.
As a result of modeling of a magnetic field structure of chemically peculiar
stars it was found that apart from the well known dipole component there
were quadrupole components unaccounted for in terms of relic mechanism. This
result requires some improvement of the theory of stellar magnetic field

Periodical increase in brightness of a white dwarf caused by gravitational amplification of radiation coming from binary systems of compact objects (white dwarfs, white dwarf and neutron star, white dwarf and black hole) can be detected in our Galaxy with a probability of 10-3 - 10-5. Deep wide field photometry allows to detect up to 10 pairs of compact objects per year. This method is presently the most effective one, especially for detection of black holes.
