Chemically peculiar stars in the field of NGC 2244.

HENSBERGE H., VRANCKEN M. and VERSCHUEREN W.

Abstract (from CDS):

Low-resolution long-slit spectra of reference stars, including MKK standard stars and well-known chemically peculiar stars, are used to develop a spectroscopic method for the detection of the 5200Å flux depression in CP stars. This new method is shown to be as sensitive a detection tool as the photometrical techniques, and provides a higher resolution view of the excess blocking. Application to stars in the field of NGC 2244 allows us to estimate and eliminate reddening effects. CP stars detected in this field include two members (#334 and #276) of the very young stellar group NGC 2244 (age ≃3x106yr) and two or three foreground stars (#381, #625 and maybe #629). #334 and #625 are strongly peculiar.
