Beta Aurigae vs. Sirius

Beta Aurigae (β Aurigae, abbreviated Beta Aur, β Aur), also named Menkalinan, is a binary star system in the northern constellation of Auriga. Sirius (a romanization of Greek Σείριος, Seirios,."glowing" or "scorching") is a star system and the brightest star in the Earth's night sky.

Am star

An Am star or metallic-line star is a type of chemically peculiar star of spectral type A whose spectrum has strong and often variable absorption lines of metals such as zinc, strontium, zirconium, and barium, and deficiencies of others, such as calcium and scandium.
