Line Identification and Excitation of Autoionizing States in a Late-type, Low-mass Wolf–Rayet Star
نویسندگان
چکیده
Identifications of a large fraction previously unidentified lines in the complex spectrum low mass, late-type LMC [WC11] star J060819.93?715737.4 have been made utilizing electronic databases. There are an exceptionally number C ii emission originating from autoionizing (AI) levels. Resonance fluorescence between ground state and excited AI levels is shown to be important photoabsorption process that competitive with dielectronic recombination exciting stellar winds, has broad application many types emission-line stars. In addition, numerous quartet multiplets appear not directly by or resonance fluorescence, signifying high wind densities region enhance collisional transfer doublet states.

Electron impact excitation of the (4p5s)P3/2,1/2 and (4p4d5s)P1/2,3/2,5/2 autoionizing states in rubidium atoms was studied experimentally by measuring the ejected-electron excitation functions and theoretically by employing a fully relativistic Dirac B-spline R-matrix (close-coupling) model. The experimental data were collected in an impact energy range from the respective excitation threshold...
