The star Epsilon Indi A is a young yellow-orange pre-main sequence star of spectral classification K5 orbited by a binary pair of magenta-hued brown dwarfs of spectral types T1 and T6.
Description (Specifications)
Epsilon Indi is a member of the Epsilon Indi moving group of more than sixteen population I stars. These stars are associated with one another due to their similar space velocity vectors, implying that they most likely formed at the same time and location.
- Epsilon Indi A is a young pre-main sequence star, meaning that it is still undergoing the late gravitational contraction phase of its formation and has not yet initiated nuclear fusion at its core.
- Epsilon Indi Ba & Bb are a mutually orbiting pair of brown dwarfs exhibiting a bright cherry-red to magenta glow as they contract and cool.
- Epsilon Indi Ba & Bb orbit one another at a distance of 2.1AU with an orbital period of about 15 years.
- Epsilon Indi Ba & Bb orbit Epsilon Indi A at a rough distance of 1460AU.
The Epsilon Indi star system lies approximately 3.6pc from Terra, and is located in a Coretrailing/Trailing direction from Terra at bearing 336.2o Galactic Longitude and -48.0o South Galactic Latitude.
