Flaring object in Orion cluster.


Abstract (from CDS):

G. C. Bower, R. Plambeck, and A. Bolatto, University of California at Berkeley, report the discovery on Jan. 20 at 86 GHz of a flaring object in the Orion cluster, detected with the Berkeley-Illinois-Maryland Association millimeter-wavelength array at an average flux density of 104 mJy (with evidence that it increased from 40 mJy at Jan. 20.188 UT to 143 mJy at Jan. 20.333). The source was not detected in observations made on 2002 Dec. 23, 2003 Jan. 11, and 14, with 3-sigma upper limits of 6, 12, and 15 mJy, respectively. Subarcsecond-resolution data yield a position of R.A. = 5h35m11s.80, Decl. = -5 21'49".2 (equinox 2000.0; error < 0".1). The source is positionally coincident with radio source A of Garay et al. (1987, Ap.J. 314, 535) and with infrared source 573 of Hillenbrand and Carpenter (2000, Ap.J. 540, 236). The object may be a deeply embedded massive protostar.
