(de) T Aurigae (también conocida como Nova Aurigae 1892) fue una nova que apareció en la constelación de Auriga en 1892. Alcanzó una magnitud de 3,8 y disminuyó a los 100 días hasta la tercera magnitud. Hoy, T Aurigae tiene magnitud 15. Fue descubierta por , quien más tarde descubriría Nova Persei 1901. (es) T Aurigae (baita ere Nova Aurigae 1892 izenarekin ezagututa) Auriga konstelazioan agertutako noba bat da. Noba horrek egun 15 magnitudeko distira du baina 3,8koa izan zuen eta, ondoren, 100 egunetan, hirugarren magnitudera jaitsi zen. 1892an zientzialariak aurkitu zuen; ikerlari berak aurkitu zuen. (eu) T Aurigae (or Nova Aurigae 1891) was a nova, which lit up in the constellation Auriga in 1891. Thomas David Anderson, an amateur astronomer in Edinburgh, reported that he was "almost certain" he saw the nova at 02:00 UT on 24 January 1892, when it was slightly brighter than χ Aurigae (apparent magnitude 4.74). He mistook the star for 26 Aurigae, although he noted to himself that it seemed brighter than he remembered it being. He saw it twice more during the following week. On 31 January 1892 he realized his mistake, and wrote a note to Ralph Copeland (the Astronomer Royal of Scotland) reporting his discovery. Professor Copeland immediately reported the discovery via telegram to William Huggins, who made the first spectroscopic observations of T Aurigae on 2 February 1892, when the star was a magnitude 4.5 object. T Aurigae was the first nova to be observed spectroscopically. Strope and Schaefer report that the peak brightness of T Aurigae was magnitude 4.5,. Pre-discovery images on photographic plates allowed the a light curve beginning in late 1891 to be constructed. AAVSO data shows that T Aurigae's quiescent magnitude is 15.3. In 1958 observations of the stars forming T Aurigae with the Crossley telescope showed that it is an eclipsing binary, with a period of 4.9 hours, and an eclipse depth of 0.18 magnitudes. T Aurigae was the third nova that was discovered to be a short period eclipsing binary, and that discovery led to increased speculation that the nova phenomenon was connected to close binary star pairs. Today it is believed that all novae are binary stars, with a "donor" star orbiting a white dwarf. The stars are so close to each other that matter is transferred from the donor star to the white dwarf. (en) T Aurigae (ou Nova Aurigae 1892) était une nova qui devint brillante en 1892, dans la constellation du Cocher. Elle atteignit une magnitude de 3,8 puis sa luminosité diminua en 100 jours d'environ 3 magnitudes (soit une magnitude d'environ 7). De nos jours, T Aurigae a une magnitude de 15. D'après la mesure de sa parallaxe réalisée par le satellite Gaia, elle est distante d'environ 880 pc (∼2 870 a.l.) de la Terre. Elle fut découverte par Thomas David Anderson, qui découvrit plus tard la Nova Persei 1901. (fr) T Возничего (лат.

Видимая звёздная величина звезды — от +15,5m до +4,1m. Вспышка новой произошла в 1891 году, через несколько месяцев после её пика, 1 февраля 1892 года её обнаружил Томас Дэвид Андерсон.
