= Mass loss
{synonym}
Loss of matter from a star or other astronomical system, for example through a <stellar wind> or explosive ejection. <Mass loss rate> conventions must distinguish the positive ejected rate $|\dot M|$ from the negative change of the retained <mass>, $\dot M$. In a <binary star>, the fate of an orbit also depends on the <specific angular momentum> carried away.
