We present results of a 90 ks Chandra X-ray observation of the young ? Orionis cluster ( -->age ~ 3 Myr ) obtained with the HETGS. We use the high-resolution grating spectrum and moderate-resolution CCD spectrum of the massive central star ? Ori AB ( -->O 9.5 V + B 0.5 V ) to test wind shock theories of X-ray emission and also analyze the high spatial resolution zero-order ACIS-S image of the central cluster region. Chandra detected 42 X-ray sources on the primary CCD (ACIS-S3). All but five…

Low-resolution spectroscopy and spectral energy distributions of selected sources towards σ Orionis
• Physics
• 2008
Aims. We study in detail nine sources in the direction of the young σ Orionis cluster, which is considered to be a unique site for studying stellar and substellar formation. The nine sources were
