More H2O maser in J-type carbon stars.


Abstract (from CDS):

The detection of five new H2O masers in J-type carbon stars is reported, confirming the suggestion made earlier that they have an oxygen-rich environment. This increases the sample of peculiar carbon stars of this type to 13. The high maser detection rate suggests that perhaps all J-type carbon stars with IRAS flux ratios S25/S12 > 0.45 have oxygen-rich environment. Two of the new stars show large radial velocities, stimulating the suggestion that these carbon stars belong to the metal-weak halo population.
