Position:

• Equatorial: 05^h29^m25.54^s, -32^d49^m03.5^s (Gaia)
• Galactic: l=236.79, b=-30.60

Finding Chart:

Charles et al. (1979)

Brightness:

Optical: G=14.0 (Gaia); X-rays: 5.9x10^-11 ergs cm^-2s^-1 (BAT 157m; 14-195 keV), 6.0x10^-11 ergs cm^-2s^-1 (2SXPS)

IP Credential:

***** (Ironclad) The spin period has been repeatedly detected in multiple X-ray observations, although it remains elusive in optical photometry. The orbital period is from optical photometry and from the grazing eclipse.

Periods:

• Orbital: 0.2285999 d = 5.486398 hr = 19751.03 s, from partial eclipes in the optical

  HJD(eclipse) = 2448267.4893(5) + 0.2285999(2)E

  (Hellier (1993))
• Spin: 0.0221 d = 31.83 min = 1909.7(2.5) s, seen in X-rays.
• Others: 5.2 hr photometric period and 4-day beat between orbit and 5.2hr.

Inclination:

~70 (has grazing eclipse).

Distance:

502.8 (499.3-506.9) pc (Gaia EDR3; parallax: 1.951+/-0.014 mas)
