Galactic ring nebulae associated with Wolf-rayet stars. VII. The nebula G 2.4 +1.4.

Abstract

Narrow band interference filter photographs and Fabry-Perot spectra are presented for the nebula G2.4 plus 1.4. In H-alpha and forbidden O III at 5007 A, the nebula shows a complex double shell structure, which appears quite different in forbidden N II at 6583 A and forbidden S II at 6732 A. The Fabry-Perot spectra show components with velocities V(LSR) between minus 20 and plus 25 km/sec. It is concluded that G2.4 plus 1.4 is a supernova remnant near the galactic center that is illuminated by the peculiar WC star LSS 4368.
