Epsilon Indi
(ε Indi, ε Ind)
(nearby star system including two brown dwarf companions)
Epsilon Indi
(aka ε Indi or ε Ind)
is a triple star system about 12 light-years away,
of which two are co-orbiting brown dwarfs (T-dwarfs).
In 2002, the radial velocity method revealed an extra-solar planet candidate;
it has been a challenge to conclusively confirm it with details,
and efforts continue.
Characteristics:
ε Ind A:
The two brown dwarfs(ε Ind B ab:), each:
- ~0.03 - mass(solar).
- 0.08 - radius(solar).
- less than 0.0001 - luminosity(solar).
(star,nearby star,binary star,brown dwarf)
