Recurrent Nova

Starfarers, 14.

A binary star. A has novaed and become a neutron star. B is a red dwarf. A, retaining most of its mass and gravity, draws matter from B. A bridge, river or cataract of hydrogen gas joins A and B. Condensed by weight and heated by its fall, the hydrogen periodically explodes into another nova. The cycle will end eventually and might culminate in a Type 1 supernova followed by a black hole. 

Poul Anderson shows cosmic events as dramatic.

From Sean M. Brooks:

Kaor, Paul!

The problem is, for short lived creatures like, such cosmic events mostly at vast distances from us of both time and space that we can't personally observe them. Preferably at a safe distance, of course!

We see such a cosmic event close up in "Day of Burning."

Ad astra! Sean
