[en] The first detection of linear polarization of the semicircular supernova remnant G109.1 - 1.0 is reported. The observations were made at 10 GHz with the Nobeyama 45-m telescope. The degree of polarization typically ranges from several to 30 %. The distribution of the projected magnetic field cannot be simply explained as tangential to the shall of the supernova remnant, but is rather consistent with the general galactic magnetic field.

[en] Observations of CO outflow and a dense molecular cloud associated with the Herbig Ae/Be star LkHα 198 have been carried out at various molecular lines with high spatial resolution. The results show that the bipolar outflow, known as a well-collimated sample, is highly asymmetric. The physical parameters of this outflow are redetermined along with a discussion concerning its driving mechanism. Secondly, dense condensations around the star reveal many different distributions in molecular lines of ¹³CO, HCO⁺, HCN, and CS. The anticorrelation between HCO⁺ and HCN condensations is remarkable among currently observed clouds, for which different molecular species generally show similar distributions. The HCO⁺ and CS condensations show velocity gradients suggestive of rotation around the star. The structures of the CO bipolar flow and of the molecular condensations strongly support the adoption of LkHα 198 as being the driving source of the outflow, rather than the nearby luminous variable V376 Cas. Finally, the stellar activities of LkHα 198 are briefly considered in connection with the variable and inhomogeneous nature of the outflow and dense molecular condensations around the star. (author)
