A finding chart for DO Dra

SkyView image of DO Dra (see important notes).

A significant fraction of papers on this LLIP calls it YY Dra. See this page for the history and the current status of the controversy over these names.

Position:
  • Equatorial: 11h43m38.54s, +71d41m20.8s (Gaia)
  • Galactic: l=130.30, b=+44.46
Finding Chart:
Patterson et al. (1992)
Brightness:
Optical: G=15.2 (Gaia); X-rays: 1.8x10-11 ergs cm-2s-1 (BAT 157mon; 14-195 keV), 5.2x10-11 ergs cm-2s-1 (2SXPS)
IP Credential:
***** (Ironclad LLIP) Both the orbital and spin periods are established beyond any reasonable doubts.
Periods:
  • Orbital: 0.165374 d = 3.96898 h = 14288.3 s (r.v. of the secondary)
    HJD = 2446863.4376(5) + 0.16537398(17) E
    (Haswell et al. 1997) for secondary's inferior conjunction.
  • Spin: 0.0061263 d = 8.8218 m = 529.31(2) s
  • Others: most X-ray power at 265s (1/2 spin period), 275/550s sidebands in the optical.
Inclination:
42+/-5.
Distance:
194.87 (193.88-195.98) pc (Gaia EDR3; parallax: 3.564+/-0.149 mas)
