About: DI Lacertae

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

DI Lacertae or Nova Lacertae 1910 was a nova in constellation Lacerta which appeared in 1910. It was discovered by Thomas Henry Espinell Compton Espin at Wolsingham Observatory on 30 Dec 1910, at which time it was an 8th magnitude object. Subsequent examination of pre-discovery photographic plates showed that the outburst occurred sometime between 17 November 1910 and 23 November 1910. It reached a peak brightness of magnitude 4.6 on 26 November 1910, making it visible to the naked eye. Before the nova event DI Lacertae was a 14th magnitude star, and by 1950 it had returned to 14th magnitude.

  • Nova Lacertae 1910 war eine Nova, die 1910 im Sternbild Eidechse aufleuchtete. Sie erreichte eine Helligkeit von 4,6 mag. Ihre Helligkeit nahm in 37 Tagen um 3 mag ab. Heute ist ihre Helligkeit 14 mag. Für die Entdeckung dieser Nova erhielt Thomas Henry Espinell Compton Espin die Jackson-Gwilt-Medaille. (de)
  • DI Lacertae or Nova Lacertae 1910 was a nova in constellation Lacerta which appeared in 1910. It was discovered by Thomas Henry Espinell Compton Espin at Wolsingham Observatory on 30 Dec 1910, at which time it was an 8th magnitude object. Subsequent examination of pre-discovery photographic plates showed that the outburst occurred sometime between 17 November 1910 and 23 November 1910. It reached a peak brightness of magnitude 4.6 on 26 November 1910, making it visible to the naked eye. Before the nova event DI Lacertae was a 14th magnitude star, and by 1950 it had returned to 14th magnitude. DI Lacertae dropped from peak brightness by 3 magnitudes in just 43 days, making it a "fast nova". All novae are binary stars, with a "donor" star orbiting a white dwarf. The two stars are so close to each other that matter is transferred from the donor star to the white dwarf. In the case of DI Lacertae, the oribital period for the binary pair is 13.050 hours, which is unusually long for a nova. The mass of the white dwarf has been estimated to be 0.91±0.2M☉In 2017 Sion et al. presented analysis of ultraviolet spectra from the Far Ultraviolet Spectroscopic Explorer and International Ultraviolet Explorer spacecraft, and found the best fit for DI Lacertae to be an accretion disk with a mass accretion rate of 10−10M☉ per year with a 30,000 Kelvin white dwarf. Darnley et al. argue that the donor star is probably a main sequence star or, less probably, a subdwarf. (en)
