A finding chart for V709 Cas

SkyView image of V709 Cas (see important notes).

Position:
  • Equatorial: 00h28m48.83s, +59d17m22.0s (Gaia)
  • Galactic: l=120.04, b=-3.46
Finding Chart:
Motch et al (1996)
Brightness:
Optical: G=14.4 (Gaia); X-rays: 7.7x10-11 ergs cm-2s-1 (BAT 157m; 14-195 keV), 3.9x10-11 ergs cm-2s-1 (4XMM-DR11)
IP Credential:
***** (Ironclad) The orbital period has been established using optical spectroscopy, while the spin period is seen in multiple X-ray observations and in optical photometry; the beat period also seen in optical photometry.
Periods:
  • Orbital: 0.2222041 d = 5.332898 hr = 19198.4 s.
    T0 = HJD 2450801.6342(16) + 0.2222041(3)
    (Thorstensen et al. 2010)
  • Spin: 0.00362014 d = 5.123 min = 312.78 s.
    No good spin ephemeris known?
  • Others: Beat period of 0.00367986 d = 5.299 min = 317.94s; also, a 0.01645 d = 1421 s period is reported?
Inclination:
?
Distance:
725.2 (716.3-734.3) pc (Gaia EDR3; parallax: 1.347+/-0.017 mas)
