A finding chart for IGR J16500-3307

SkyView image of IGR J16500-3307 (see important notes).

Position
  • Equatorial: 16h49m55.63s, -33d07m02.2s (Gaia)
  • Galactic: l= 349.70, b=+7.34
Finding Chart:
Masetti et al. (2008)
Brigntness:
Optical: G=15.9 (Gaia); X-rays: 2.3x10-11 ergs cm-2s-1 (BAT 157m; 14-195 keV); 1.2x10-11 ergs cm-2s-1 (4XMM-DR11)
IP Credential:
***** (Ironclad): The X-ray period has been detected at 571.9 s; the previously detected optical photometric period of 597.92 s is the beat between the X-ray period and 3.617 hr orbital period from optical spectroscopy.
Periods:
  • Orbital: 0.1507 d = 3.617 h = 13021 s from optical spectroscopy.
  • Spin: 0.006619 d = 9.532 min = 571.9 s from X-rays.
  • Others: 0.006920 d = 9.9653 min = 597.92 s from optical photometry is the beat period.
Inclination:
?
Distance:
1091 (1039-1146) pc (Gaia EDR3; parallax: 0.878+/-0.046 mas)
