It doesn't but the paper's abstract mentions the HD identifier, so you can look it up on SIMBAD[1] to get the parallax. While parallaxes aren't the best measure of distance (they really aren't very good at all) you can get an okay estimation by taking [d = 1/p] where d is in parsecs and p is in arcseconds. Saving you the math, it's about ~188 ±20 parsecs (~564±60 ly).
