Arcturus

Arcturus

I chose Arcturus because it is one of the brightest stars in out solar system.
Chemicals: contains "metals", elements with higher atomic numbers than helium, C, O, Na, Mg, Al, Si, K, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, and Zn
Location: RA 14^h 15^m 39.7^s | Dec +19° 10′ 56''
Stellar Classification: K0 III orange giant star

Arcturus of the constellation Boötes is the brightest star in the northern celestial hemisphere. With a visual magnitude of −0.05, it is the fourth brightest star in the night sky. Arcturus is a type K0 III orange giant star, with an absolute magnitude of −0.30. It has likely exhausted its hydrogen from its core and is currently in its active hydrogen shell burning phase. It will continue to expand before entering horizontal branch stage of its life cycle.

 Astronomers term "metals" those elements with higher atomic numbers than helium. Arcturus has an enrichment of alpha elements relative to iron but only 17 to 32% metallicity relative to our Sun. Abundances of the following elements are measured from an equivalent width analysis of atomic features: C, O, Na, Mg, Al, Si, K, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, and Zn, and the chemical composition of Arcturus typical of that of a local thick-disk star, consistent with its kinematics.

It is located at  RA 14^h 15^m 39.7^s | Dec +19° 10′ 56''.
