Astronomers Observe Brown Dwarf Transferring Mass to an M Dwarf

Nature reports the first direct observation of stable, long-lived mass transfer from a substellar object onto a main-sequence star. The system ZTF J0440+2325, with an 87-minute orbit, shows a brown dwarf feeding an M dwarf, suggesting some substellar objects are gradually consumed over very long timescales.
