[1] Anomalous eclipses of the young star rw aur a / S. Lamzin, D. Cheryasov, G. Chuntonov et al. // Stars: From Collapse to Collapse. Proceedings of a conference held at Special Astrophysical Observatory, Nizhny Arkhyz, Russia. — Vol. 510 of ASP Conference Series. — Astronomical Society of the Pacific San Francisco, 2017. — P. 356. Results of UBVRIJHKLM photometry, VRI polarimetry and optical spectroscopy of a young star RW Aur A obtained during 2010-11 and 2014-16 dimming events are presented. During the second dimming the star decreased its brightness to ΔV >4.5 mag, polarization of its light in I-band was up to 30 %, and color-magnitude diagramm was similar to that of UX Ori type stars. We conclude that the reason of both dimmings is an eclipses of the star by dust screen, but the size of the screen is much larger than in the case of UXORs.
