Stars of Taurus

Sun and solar corona passing through Taurus constellation, 31st June 2003.

22 images, about 1 per hour.

Most stars are known by more than one name; have included some alternatives in brackets:

Aldebaran (Alpha Tauri, α Tau) is an orange giant 44 times the size of the Sun, 65 light years away.

Sigma Tauri (σ Tau) is a double star; both components are white dwarfs, 155 light years from the Sun.

Rho Tauri (ρ Tau) is a white dwarf with nearly twice the mass of the Sun, 152 light years away.

Theta Tauri (θ Tau) is another double star but the components, an orange giant and a white giant, are 154 and 150 ly away respectively and the 4 light years separation makes it unlikely they are a binary system.

Hyadum I (the First Hyad, Gamma Tauri, γ Tau) is a red giant in the Hyades star cluster, 154 light years from Earth. Hyadum I is 85 times brighter than the Sun.

Hyadum II (the Second Hyad, Eudora, Delta Tauri, δ Tau), also identified with the Hyades, actually three separate star systems, two of which are composed of three stars – astronomy can be confusing.

Ain (Oculus Borealis, Epsilon Tauri, ε Tau) is an orange giant 147 light years from the Sun. Ain is derived from the Arabic for “eye”; Oculus is from the Latin (Borealis means “north”, as in Aurora Borealis).

Omega Tauri (ω Tau) is an orange giant 291 light years from the sun
