Nature of OH maser and SiO thermal emission towards carbon star: IRAS 05373-0810 (V1187 Ori).

Abstract (from CDS):

We present observational evidence that IRAS05373-0810 is a genuine carbon star with an ISO SWS spectrum closely resembling that of RScl. Modelling of the spectral energy distribution of IRAS05373-0810 suggests that the star has luminosity of order of 8000 L_☉ and loses mass at a rate of about 2-3x10^–7M_☉/yr. The detected OH maser emission at 1612, 1665 and 1667MHz and SiO thermal emission at 86.85GHz towards IRAS 05373-0810 is not associated with this source. The available observations imply that these lines, typical for O-rich sources, come from the molecular cloud L1641 in the Orion star forming region (OH) and, very likely, from the NGC 2149 molecular complex (SiO).
