BD+20 1790 b - A planet found serendipitously (so they say)

Though between uncertain planetary candidates

But dear Jean Schneider an age of 57 Gyrs is quite much for a young and active star! Razz

From the abstract of the discovery paper, it seems that the serendipitous nature of the discovery comes from the fact that they've been observing the star over a few years. They state that BD+20 1790 is a highly active, young star
Previous results show ahigh level of stellar activity, with the presence of prominence-likestructures, spots on surface and strong flare events.
Haven't read the paper of course, but it seems that after monitoring it for so long, they were able to disentangle a planet-induced curve to the (no doubt) noisy RV data.
