   Sammanfattning : Context. Effective temperature is one of the fundamental stellar parameters. A traditional spectroscopic way to determine it is from optical spectra using excitation balance of Fe-lines. LÄS MER

3. 2. Line Identification and Temperature Diagnostics of Eta Carina's Sr-Filament

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Henrik Rhodin; [2013]
   Nyckelord :η Carinae; Sr-Filament; X-Shooter; Near-Infrared NIR Spectra; line list; forbidden lines; Boltzmann Plot; Temperature Diagnostics; Physics and Astronomy;

   Sammanfattning : This bachelor thesis concerns the NIR spectral region of the Sr-filament, a substructure of the fan located in the equatorial skirt of Eta Carinae. The primary objective was to identify emission features intrinsic to the Sr-filament, and to tabulate these in a line-list spanning the spectral range λλ990 − 2410 nm. LÄS MER
