| dbo:abstract | HD 32188 is suspected variable star in the northern constellation of Auriga, and is positioned roughly in between Eta and Zeta Aurigae. It has a white hue and is just barely visible to the naked eye with an apparent visual magnitude that fluctuates around 6.08. The distance to this star is approximately 3,000 light years, based on parallax. It has an absolute magnitude of −2.87. This object is an A-type giant star with a stellar classification of A2IIIshe. The suffix notation indicates this is a shell star, which means it has a peculiar spectrum indicating there is a circumstellar disk of gas around the star's equator. While the spectral luminosity class is III, analysis of its colour and brightness suggest it more closely resembles a supergiant star. HD 32188 has expanded to 30 times the radius of the Sun and it is spinning with a projected rotational velocity of 23 km/s. It is radiating 2,428 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 7,350 K. (en) HD 32188 è una stella gigante bianca di magnitudine 6,12 situata nella costellazione dell'Auriga. Dista 2038 anni luce dal sistema solare. (it) HD 32188 är en ensam och misstänkt variabel stjärna belägen i den mellersta delen av stjärnbilden Kusken, mellan Eta och Zeta Aurigae. Den har en skenbar magnitud av ca 6,08 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 1,1 mas, beräknas den befinna sig på ett avstånd på ca 3 000 ljusår (ca 920 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca –0,7 km/s.
