On the nature of photometric activity of the young star V2492 Cyg

The article provides a brief overview of the work carried out over several years to study the photometric activity of the young star V2492 Cyg. After the discovery of the flare of this star in August 2010, intensive multi-wave photometric and spectral observations were carried out, on the basis of which contradictory results were obtained regarding the classification of the object and, as a consequence, the determination of the main mechanism responsible for the variability of radiation. The initial statement that this is uxor and its variability is due to extinction on the line of view contradicted the spectroscopy data, which indicated an obvious outflow of matter caused by accretion. Currently, it is believed that photometric activity is due to both the accretion of matter from the disk onto the star and variable extinction caused by various gas-dust structures on the line of view.
