J/A+A/467/665    Manganese abundances in the Galactic disk     (Feltzing+, 2007)

Manganese trends in a sample of thin and thick disk stars. The origin of Mn. Feltzing S., Fohlman M., Bensby T. <Astron. Astrophys. 467, 665 (2007)> =2007A&A...467..665F
ADC_Keywords: Stars, nearby ; Stars, late-type ; Abundances Keywords: stars: abundances - Galaxy: abundances - stars: late-type Abstract: Manganese is an iron-peak element and although the nucleosynthesis path that leads to its formation is fairly well understood, it remains unclear which objects, SN II and/or SN Ia, that contribute the majority of Mn to the interstellar medium. It also remains unclear to which extent the supernovae Mn yields depend on the metallicity of the progenitor star or not. Description: Manganese abundances for thin and thick disk stars from Bensby et al. (2003, Cat. J/A+A/410/527 and 2005, Cat. J/A+A/433/185) have been observed with two spectrographs. FEROS on the ESO1.5m and SOFIN on the NOT telescope. For stars that were observed with FEROS we obtained Mn abundances (using synthetic spectra) from four lines (table4) and for stars observed with SOFIN for two lines (table5). File Summary:
