At 2 kpc M17 is the nearest giant HII region, with 10,000 stars younger than 1 Myr and a prominent X-ray champagne flow. At the heart of M17 are CEN 1A and 1B, a visual pair of O4 stars separated by only 1.8". A long series of ACIS observations show that each O4 star is a very hard time variable X-ray source. We suggest that one or both O4 stars are themselves colliding wind shock binaries or, alternatively, that one or both have strong magnetic fields. We propose to obtain time-resolved, spatially resolved HEG/MEG spectra of both stars to measure He-like line ratios and line profiles to directly test these two models. This roll-constrained 150-ks GO proposal is tied to a 25-ks GTO proposal (PI: Garmire) for the same target.
