Weighing potentially habitable planets around Sun-like stars remains surprisingly difficult: a methods test found that precise measurements often require planets weighing about 8 to 10 Earth masses. The latest reports also explore brilliant radio bursts from a rapidly spinning brown dwarf, a possible hotspot on another brown dwarf, and how transit changes can expose a planet that never crosses its star.

Image: Two warm sub-Neptunes discovered transiting nearby K-type star HD 15906
The HD 15906 system is one of only six multi-planet systems with two warm (< 700 K) sub-Neptune sized planets transiting a bright star (G < 10 mag). It is an excellent target for detailed characterisation studies to constrain the composition of sub-Neptune planets and test theories of planet formation and evolution....
