ESA THESEUS and cataclysmic variables

Abstract

The capabilities of the considered space mission THESEUS for investigation of cataclysmic variables (CVs) are discussed.Transient High-Energy Sky and Early Universe Surveyor (THESEUS) is a space mission proposal accepted by the European Space Agency for a phase A study that would study gamma-ray bursts and X-rays for investigating the early universe and for the multimessenger astrophysics. It involves a Lobster-Eye X-ray telescope as well. The THESEUS and SMILE international consortia involve the Czech Technical University in Prague and the Czech teams are expected to contribute to the project, mainly to the X-ray telescope and related science and software.
