DU Lyncis

DU Lyncis is a recurrent nova located in the constellation Lynx. It was first observed in 1928, reaching a peak brightness of magnitude 7.0. Its light curve displays characteristics typical of a fast nova, with a rapid increase in brightness followed by a gradual decline.

DU Lyncis is a binary system consisting of a white dwarf star and a companion star, likely a red dwarf. The nova outbursts are caused by the accretion of material from the companion star onto the surface of the white dwarf. When sufficient material has accumulated, a thermonuclear runaway occurs, resulting in a sudden and dramatic increase in brightness.

The period between outbursts for DU Lyncis is relatively short, placing it within the category of recurrent novae. Its recurrent nature allows astronomers to study the nova phenomenon in detail and to monitor the evolution of the binary system. Further observations and analyses of DU Lyncis contribute to our understanding of novae and the processes occurring in close binary stars. Its coordinates are approximately RA 06h 56m 49s, Dec +48° 08′ 47″.
