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).
