Iota Virginis (ι Vir, ι Virginis) is a star in the constellation Virgo. It has the traditional name Syrma.[3]
Syrma is a yellow star of apparent magnitude 4.08 and spectral class F6 III about 70 light years from Earth. This star has 1.52 times the mass of the Sun,[4] with a projected rotational velocity of 14.8 km s−1.[2] It is radiating 8.6 times the luminosity of the Sun from its outer atmosphere at an effective temperature of 6,282 K.[1] The radius is about 2.5 times that of the Sun.[5]
In culture
- The name Syrma is from the Arabic (سرما (تطريز sirmā "train" (of a garment).
- In China, 亢宿 (Kàng Xiù), meaning Neck, refers to an asterism consisting of this star, κ Virginis, κ Virginis and λ Virginis.[6] Consequently, ι Virginis itself is known as 亢宿二 (Kàngsuèr, English: the Second Star of Neck.)
