| dbo:abstract | 41 Tauri is a single-lined spectroscopic binary system in the zodiacal constellation of Taurus; 41 Tauri is its Flamsteed designation. The star has a visual magnitude of 5.19, making it visible to the naked eye from brighter suburban skies (according to the Bortle scale). Parallax measurements put it at a distance of roughly 404 light years from the Sun. This is a chemically peculiar star and was first classified as a silicon star by American astronomer William Morgan in 1933. The stellar spectrum displays an overabundance of heavier elements; particularly silicon and gallium. These abundances may be caused by the magnetic field of the star, which produces concentrations of the observed elements in the outer atmosphere. It is an α² Canum Venaticorum-type variable star, ranging in magnitude from 5.15 down to 5.22. These variations are likely due to large spots or rings on the side of the star being observed. The star and its companion orbit each other closely with a period of a week and an eccentricity of 0.18. The rotation period of the primary star has become locked to its orbit, so that one face is always pointed toward its companion. The abundance of gallium and silicon varies in a sinusoidal pattern that matches this period. The primary has around 2.9 times the mass of the Sun, 3.5 times the Sun's radius, and is emitting 190 times the luminosity of the Sun. The effective temperature of the star's photosphere is 12,600 K, giving it the blue-white hue of a B-type star. (en) 41 Tauri est une étoile binaire du Taureau, située à ∼420 a.l. (∼129 pc) de la Terre. (fr) 41 Tauri, som är stjärnans Flamsteed-beteckning, är en enkelsidig spektroskopisk dubbelstjärna belägen i den norra delen av stjärnbilden Oxen, som också har variabelbeteckningen GS Tauri. Den har en genomsnittlig skenbar magnitud på ca 5,19 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 7,8 mas, beräknas den befinna sig på ett avstånd på ca 420 ljusår (ca 129 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet av ca -2 km/s.
