Overview

Analysis reveals a possible black hole nature, determining the orbital period and donor star characteristics.

Key Points

  • A coherent double-humped modulation was detected with a period of 0.0941 days, indicating a probable short orbital period.
  • Interstellar extinction was quantified as E(B-V)=0.60±0.05, placing the system's distance between 2.8 and 4.0 kpc.
  • The study combined optical photometry and spectroscopy using data from multiple telescopes during outburst and quiescence.
  • The findings suggest it may be a low-inclination black hole X-ray transient, yet the possibility of being a neutron star accretor remains.
