A finding chart for MU Cam

SkyView image of MU Cam (see important notes).

  • Equatorial: 06h25m16.25s, +73d34m39.1s (Gaia)
  • Galactic: l=140.86, b=+24.12
Finding Chart:
Staude et al (2003)
Optical: G=14.8 (Gaia); X-rays: 1.6x10-11 ergs cm-2s-1 (BAT 157m; 14-195 keV), 1.1x10-11 ergs cm-2s-1 (4XMM-DR11)
IP Credential:
***** (Ironclad): The spin, the orbital, and the beat periods are firmly established through extensive optical photometry, X-ray observation (for the spin), and optical spectroscopy (for the orbital and the spin periods).
  • Orbital: 0.19661 d = 4.7186 hr = 16987 s, seen in optical spectroscopy and photometry.
    BJD = 2452682.464(3) + 0.19661(27)E
    for the sharp rise from the minimum (Staude et al 2003).
  • Spin: 0.013740954 d = 19.786974 min = 1187.2184 s, seen in optical photometry.
    T = 2454085.50766(25) + 0.013740954(16)E-1.635(23) 10-12 E2
    (Petrik et al 2015).
  • Others: 0.0147725 d = 21.2723 min = 1276.34 s sideband also seen in optical photometry.
