HD 134687 (e Lupi) is a binary star system in the southern constellation Lupus.
[2] The distance to HD 134687 can be estimated from its annual parallax shift of 7.6 mas,[1] yielding roughly 430 light years.
The primary has an a sin i value of 2.735×105 km, which only gives a lower bound for the semimajor axis a since the orbital inclination i to the line of sight is unknown.
[12] The visible component has a stellar classification of B3 IV/V,[3] matching a B-type star showing a spectrum with mixed traits of a main sequence and a subgiant star.
It is radiating 997[2] times the Sun's luminosity from its photosphere at an effective temperature of 17,100 K.[2]
