The Exoplanets That Never Were

StartsWithABang writes In 1992, scientists discovered the first planets orbiting a star other than our Sun. The pulsar PSR B1257+12 was discovered to have its own planetary system, and since then, exoplanet discoveries have exploded. But before that, in 1963, decades of research led to the much-anticipated publication and announcement of an exoplanet discovered around Barnard's star, the second-closest star system to Earth. Unfortunately, it turned out to be spurious, and it took years to uncover, an amazing story which is only now fully coming to light.

Red dwarfs form from so little matter by jfdavis668 · 2014-09-10 13:35 · Score: 3, Interesting

I'm not surprised that there are no planets. Red dwarfs form from very small amounts of matter, and don't have the luminosity or stellar wind to stop the in-fall of matter into the central star. I don't doubt they can form, the same way double stars form, but the odds are lower. Just a lot less initial material to start with.
