Published Papers
Miscellaneous :

Reig et al. 2005 :
  • spectrum shows the presence of H beta and gamma emission lines
  • metallic and HeI lines typical of early B star
  • B~14.68, V~13.29, R~12.32, I~11.37, (slight variations)
  • estimated distance 2 kpc
Tomsick et al. 2008:
  • Chandra reveals 3 sources within INTEGRAL error box.
  • No X-ray source at position of the B star
  • Upper limit on the 0.3-10 keV source flux at position of B star 3.2-4.1e-14 erg/s/cm2
  • At d=2 kpc L<2e31 erg/s significantly lower than quiescent lum of other Be XRBs
Tomsick et al. 2011:
  • XMM, Optical/IR and Chandra analysis of the field of IGR J01363+6610.
  • Updated IBIS position => 7 X-ray objects in both XMM and Chandra
  • 1 is consistent with the Be star => also an X-ray source
  • Be star is the counterpart to the IGR
  • X-ray spectra fitted with an absorbed power law with Γ=1.4 and NH=1.5 x1022 cm-2
  • Very low quiescent luminosity compared to other sources
  • Possible Be-binary with a black hole, or that a large circular orbit could be the reason for low luminosity
Corbet and Krimm 2010 ATel 3079 :
  • 160 day period in the Swift/BAT light curve
  • Modulation is only present in recent data
  • sine wave fit => Tmax = MJD 55,291 + n x 159
  • Caution since only a small number of 160 day cycles are covered
