Transient Heavy Element Absorption Systems in Novae: Episodic Mass Ejection from the Secondary Star
A high-resolution spectroscopic survey of post-outburst novae reveals short-lived heavy element absorption systems in a majority of novae near maximum light, having expansion velocities of 400-1000 km s-1 and velocity dispersions between 35 and 350 km s-1. A majority of systems are accelerated outward, and they all progressively weaken and
