X-ray properties of HM1 and IC2944/2948
Listed in IVOA Registry (Virtual Observatory)
Using XMM-Newton data, we study for the first time the X-ray emission of HM1 and IC2944/2948.
Description
Low-mass, pre-main sequence objects with an age of a few Myr are detected, as well as a few background or foreground objects. Most massive stars in both clusters display the usual high-energy properties of that kind of objects, though with log(Lx/Lbol) apparently lower in HM1 than in IC2944/2948.
Comparing with studies of other clusters, it seems that low S/N at soft energies, due to the high extinction, may the main cause of this difference. In HM1, the two Wolf-Rayet stars show contrasting behaviours: WR89 is extremely bright, but much softer than WR87. It remains to be seen whether wind-wind collisions or magnetically confined winds can explain such emissions.

In IC2944/2948, the X-ray sources concentrate around HD101205; a group of massive stars to the north of this object appears rather isolated, suggesting that there exist two subclusters in the field-of-view.
