DQ Herculis = Nova Herculis 1934

A finding chart for DQ Her

SkyView image of DQ Her (see important notes)

  • Equatorial: 18h07m30.12s, +45d51m32.7s (J2000)
  • Galactic: l=73.15, b=+26.44
Finding Chart:
Optical ; fx (2-10 keV)~?
IP Credential:
***** (Confirmed)
  • Orbital: 0.19362 d = 4.65 hr = 16729 s, from optical eclipses.
    Tmin = HEJD 2434954.94429(8) + 0.1936208964(12)E
    (Zhang et al. 1995, who also give a quadratic version).
  • Spin: 8.2252e-02 day = 1.18 min = 71.066 s, seen in optical photometry.
    Tmax = HEJD 2439628.77177(3) + 8.22518320(3)e-04 E - 2.62(4)e-16 E^2 + 2.8(1)e-24 E^3
    (Zhang et al. 1995). The 71 s period has long been thought to be the spin period, but Zhang et al. 1995 prsents strong (but indirect) evidence that the true spin period is twice this value.
  • Others:
~90 deg (deep eclipse, front half of disk is probably hidden)
525+/-28 pc (Vaytet, O'Brien & Rushton 2007; see also Herbig & Smak 1992, who obtained 561+/-19 pc)


We will not even attempt to compile a complete list of pre-1980 papers that deal exclusively with the classical nova event of 1934; see the Bode and Evans book on Classical Novae for that.
