Star in the constellation Taurus
This article is about t Tauri. For the variable star, see
T Tauri .
6 Tauri , also designated t Tauri , is a chemically peculiar star in the northern constellation of Taurus . It has an apparent visual magnitude of 5.8, so, according to the Bortle scale , it is faintly visible from suburban skies at night. Measurements made with the Gaia spacecraft show an annual parallax shift of mas light years from the Sun.
A stellar classification of B9III matches that of a B-type giant star , but a more detailed analysis gives a type of kB8HeB9.5V(HgMn), indicating a main sequence mercury-manganese star . Mercury-manganese stars are chemically peculiar stars with a specific over-abundance of mercury and manganese absorption lines in their spectra.[ 5] [ 7]
6 Tauri has a mass 2.8 times that of the Sun and a radius 2.5 times the Sun's . With an effective temperature of K bolometric luminosity of 79 L ☉ Evolutionary models indicate that it is still on the main sequence with an age of 224 million years.[ 1]
