An XMM-Newton view of the young open cluster NGC 6231 - II. The OB star population.
SANA H., RAUW G., NAZE Y., GOSSET E. and VREUX J.-M.
Abstract (from CDS):
Among B-type stars, the detection rate is only about 25 per cent in the subtype range B0-B4 and remains mostly uniform throughout the different subpopulations while it drops significantly at later subtypes. The associated X-ray spectra are harder than those of O-type stars. Our analysis points towards the detected emission being associated with a physical (in a multiple system) PMS companion. However, we still observe a correlation between the bolometric luminosity of the B stars and the measured X-ray luminosity. The best-fitting power law in the 0.5-10.0keV band yields logLX= 0.22(±0.06) logLbol + 22.8(±2.4).
