An extreme test case for planet formation: a close-in Neptune orbiting an ultracool star

Gudmundur Stefansson, Suvrath Mahadevan, Yamila Miguel +27

In current theories of planet formation, close-orbiting planets as massive as Neptune are expected to be very rare around low-mass stars. We report the discovery of a Neptune-mass…
