Two small exoplanets discovered around nearby star LHS 1678, also maybe a brown dwarf

Astronomers discovered 2 new exoplanets in orbit around star LHS 1678. Both of them are smaller than Earth, although one is more massive. The system of the star LHS 1678 might also contain a brown dwarf and third exoplanet, but those have not been confirmed with observations from another observatory.
