A Big Surprise : Close-in Jupiters
It is easiest to find a massive planet
that is close to the star (it repeats quickly and has a large velocity
amplitude). The first discovery, 51 Peg, had a 4 day orbit (0.05 AU!) and the
mass of Jupiter. Many are now known, but that doesn’t mean they are most
common, just easiest to find (and present in some numbers).
