Overview

Randomized trial reveals the properties of dwarf nova outbursts in post-novae, suggesting new insights into their behavior.

Key Points

  • This research investigates the episodic dwarf nova outbursts in post-novae AT Cancri and GK Persei.
  • Utilized CCD and visual observations from AAVSO and Zwicky Transient Facility.
  • Analyzed digitized photographic data from Harvard's Digital Access to a Sky Century database.
  • Documented outburst occurrences and analyzed light curve properties.
  • Individual outbursts emit varying energy levels in the optical band, even for adjacent outbursts.
  • Cycle lengths (T C) show small fluctuations while experiencing considerable long-term variation.
  • Outbursts in AT Cancri decay more slowly compared to other dwarf novas of similar orbital periods not known to have classical nova eruptions.
