Rare multiple star system discovered

Scientists using NASA's Fermi space telescope have discovered one of the most instense energy sources in the comsos - a rare gamma-ray binary star system.
The discovery opens a new window on these extremely high energy sources.
A binary star system consists of two stars orbiting each other.

Title: The Distance of the Gamma-ray Binary 1FGL J1018.6-5856
Authors: Vanessa J. Napoli, M. Virginia McSwain, Amber N. Marsh Boyer, Rachael M. Roettenbacher

The recently discovered gamma-ray binary 1FGL J1018.6-5856 has a proposed optical/near-infrared (OIR) counterpart 2MASS 10185560-5856459. We present Stromgren photometry of this star to investigate its photometric variability and measure the reddening and distance to the system. We find that the gamma-ray binary has E(B-V) = 1.34 ±0.04 and d = 5.4^+4.6_-2.1 kpc. While E(B-V) is consistent with X-ray observations of the neutral hydrogen column density, the distance is somewhat closer than some previous authors have suggested.
