About: HD 33463

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

HD 33463 is a suspected variable star in the northern constellation of Auriga, about 1,050 light years away. It is a red giant star with a stellar classification of M2III, and has expanded away from the main sequence after exhausting its core hydrogen. It has reached 133 times the size of the Sun and, at an effective temperature of 3,753 K it shines at a bolometric luminosity of 2,114 L☉.

dbo:abstract
  • HD 33463 is a suspected variable star in the northern constellation of Auriga, about 1,050 light years away. It is a red giant star with a stellar classification of M2III, and has expanded away from the main sequence after exhausting its core hydrogen. It has reached 133 times the size of the Sun and, at an effective temperature of 3,753 K it shines at a bolometric luminosity of 2,114 L☉. Hipparcos satellite data showed possible variations in the apparent magnitude of HD 33463 and it was given the suspected variable star designation NSV 16257. Observations with MASCARA, a camera designed to detect exoplanets, show brightness variations with a maximum amplitude of 21 thousandths of a magnitude and a period slightly less than a day. (en)
  • HD 33463 è una stella gigante rossa di magnitudine 6,45 situata nella costellazione dell'Auriga. Dista 1144 anni luce dal sistema solare. (it)
  • HD 33463 är en ensam stjärna belägen i den södra delen av stjärnbilden Kusken. Den har en skenbar magnitud av ca 6,44 och kräver åtminstone en handkikare för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 3,1 mas, beräknas den befinna sig på ett avstånd på ca 1 000 ljusår (ca 320 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 11 km/s. (sv)
