49.51d 2MASS J14484322-5942137 Rodriguez et al. 2010
Published Papers
Miscellaneous :
Landi et al. 2009 ATel 2355:
  • 2MASS counterpart with J ~15.5, H ~13.5 and K ~12.5
Rodriguez et al. 2010 (A&A):
  • Swift observations => 2 possible X-ray counterpart
  • Source #1 absorbed and preferred counterpart
  • Source is prbably Galactic
Corbet et al. 2010 ATel 2598:
  • 15-100 keV Swift light curve => significant modulation at ~49d
  • A sine wave fit leads to:
    Tmax = MJD 54 318.1 + n x 49.51
  • Search for a spin period in the 2 possible counterparts found with XRT: marginal signal at 33.4s in one source but do not favour this object as the counterpart to the IGR.
  • Pulsation interpreted as orbital period of an HMXB possibly a Be type.
Coleiro et al. (2013) :
  • NTT/Sofi NIR Spectroscopy
  • Potential emission lines He I and Br&gamm; with the same intensity
  • More probably an Oe/Be star
