calcium-rich gap transient

(calcium-rich supernova)
(type of explosive event larger than a nova and smaller than a supernova)

A calcium-rich gap transient (or calcium-rich supernova) is an observed transient within the gap in transient-sizes between a nova and supernova, that is rich in calcium spectral lines. No model is yet fully accepted, but typical supernova explanations (core collapse and thermonuclear explosion) are generally rejected. Extant theories involve white dwarfs and/or neutron stars or even a merger of both.
