Overview

Extensive observations confirmed coherent oscillation in the cataclysmic variable, suggesting it is an intermediate polar.

Key Points

  • The aim was to precisely measure the photometric period of 1RXS J014549.6+514314 based on extensive observations.
  • Conducted extensive photometry over 25 nights from 2022 to 2024.
  • Total observation duration was 139 hours.
  • Monitored oscillation to determine its period and coherence.
  • Confirmed a coherent oscillation period of approximately 41 minutes.
  • The semi-amplitude of the oscillation averaged 0.154(2) mag.
  • Created an ephemeris for the oscillation valid for 30 years.
