Abstract
Searches of archival X-ray data have revealed galaxies exhibiting nuclear quasi-periodic eruptions. Repeated, partial stripping of a white dwarf in an eccentric orbit around a black hole is a proposed model. A new X-ray nuclear transient, Swift J0230, shows quasi-periodic outbursts with a period of weeks, bridging existing classes of periodic nuclear transients. Its discovery highlights the importance of low-latency X-ray transient searches.
