Tutuł wystąpienia: "Life cycles of symbiotic novae"
Accreting white dwarf binaries are the most common interacting binaries in the Universe. The accretion leads to various outburst phenomena; among the most spectacular are thermonuclear nova explosions recurring with timescales from months to millions of years. The thermonuclear novae are also one of the most violent stellar explosions, contributing to galactic chemical evolution. Symbiotic novae are those with evolved giant donors. They are very suitable to study nova life cycles, because they have the higher accretion rates and shorter recurrence timescales than those with less evolved donors. I am going to present the state-of-the-art in understanding of them with emphasis on the recent results and discoveries.
