White dwarfs with jets as non-relativistic analogues of quasars and microquasars?

摘要

We explore the similarities between accreting white dwarfs (CH Cyg and MWC 560) and the much more energetic jet sources — quasars and microquasars. To-date we have identified several common attributes: (1) they exhibit collimated outflows (jets); (2) the jets are processing; (3) these two symbiotic stars exhibit quasar-like emission line spectra; (4) there is a disk-jet connection like that observed in microquasars. Additionally they may have a similar energy source (extraction of rotational energy from the accreting object). Study of the low energy analogues could have important implications for our understanding of their higher energy cousins.
