Tau Eridani

Tau Eridani (τ Eridani, τ Eri) is a group of fairly widely scattered stars in the constellation Eridanus.

• τ¹ Eridani (1 Eridani)^[1]
• τ² Eridani (2 Eridani)^[2]
• τ³ Eridani (11 Eridani)^[3]
• τ⁴ Eridani (16 Eridani)^[4]
• τ⁵ Eridani (19 Eridani)^[5]
• τ⁶ Eridani (27 Eridani)^[6]
• τ⁷ Eridani (28 Eridani)^[7]
• τ⁸ Eridani (33 Eridani)^[8]
• τ⁹ Eridani (36 Eridani)^[9]

Because of the large separation of the stars, sometimes they were not designated like above. For example, in Lacaille’s catalogue, τ⁶ was designated n, τ⁶ was designated n, τ⁷ was designated m, and τ⁹ was designated k. In Bode’s catalog, only τ¹ and ² were designated Tau. τ³ was designated E, τ⁴ was designated j, τ⁵ was designated t, τ^6,7 were designated m, and τ^8,9 was designated l^[10]. These designations were not withheld and reverted to the chain of Tau stars. All of them were member of asterism 天苑 (Tiān Yuàn), Celestial Meadows, Hairy Head mansion .^[11]
