KO Velorum = E1013-477 = H1011-47

A finding chart for KO Vel

SkyView image of KO Vel (see important notes).

Position:
  • Equatorial: 10h 15m 58.42s, -47d 58m 11.3s (J2000)
  • Galactic: l=277.88, b=+7.20
Finding Chart:
Mason et al (1983)
Brightness:
white light: 16.7-17.7; fx (1-9 keV)~8.0x10^(-12) ergs/cm/cm/s (EXOSAT)
IP Credential:
* (Doubtful): Although variable on 1 hr timescales, no single, coherent periodicity has been seen. Claims of periodicities are compromised by high harmonics of the orbital modulation and by flickering.
Periods:
  • Orbital: 6.4 hr? 4.9 hr? 10.1 hr?
  • Spin: various ~1 hr timescales have been proposed.
    Inclination:
    ?
    Distance:
    ?
