Abstract
We present high resolution (
0.2)
AO-corrected coronographic near-infrared imaging on the early-type Herbig Be star MWC 297.
X-ray flaring has been reported towards this young
object, however this has been difficult to reconcile with its early spectral type (B1.5) and relatively high
mass (~10 
). Our infrared and X-ray analysis shows
that the X-ray flaring is likely due to a late-type star in the same field.
The case of MWC 297 emphasizes the need for coronographic imaging to address the reality of X-ray emission
towards Herbig Ae/Be stars, which is needed to understand the differences
between low and high-mass star formation.
Key words: stars: formation -- stars: pre-main sequence -- stars: flare -- stars: individual: M 297 -- X-rays: stars
