Symbiotic binaries in the era of Gaia and other surveys

Abstract

Symbiotic stars are strongly interacting binaries with long orbital periods, containing an evolved red giant and a white dwarf or a neutron star embedded in a circumbinary nebula. The diverse processes occurring in these systems make them unique astrophysical laboratories and objects suitable for studies spanning virtually all the wavelengths, from γ-rays and X-rays through UV, optical, and infrared to radio waves. However, although the first symbiotic stars were discovered more than a century ago, many questions regarding their parameters, evolution, or symbiotic population remain open, even in the era of massive ground- and space-based surveys such as the groundbreaking Gaia, as well as modern machine-learning techniques. In this talk, I will review the most important information on symbiotic stars and introduce our ongoing projects aimed at providing a 'clean' sample of these interacting binaries, discovering new objects of this class, better characterizing their parameters, and ultimately helping us to understand the symbiotic population as a whole.
