Chandra X-ray observatory study of the Orion nebula cluster and BN/KL region.
GARMIRE G., FEIGELSON E.D., BROOS P., HILLENBRAND L.A., PRAVDO S.H., TOWNSLEY L. and TSUBOI Y.
Abstract (from CDS):
The sources in the Becklin-Neugebauer/Kleinman-Low region of massive star formation are discussed in detail. They include both unabsorbed and embedded low-mass members of the Orion Nebula cluster, the luminous infrared Source n, and a class of sources without optical or infrared counterparts that may be new magnetically active embedded PMS stars. Several X-ray sources are also variable radio emitters, an association often seen in magnetically active PMS stars. Faint X-ray emission is seen close to, but apparently not coincident with, the Becklin-Neugebauer object. Its nature is not clear.
