Abundance determination in HII regions from spectra without the [OII]3727+3729 line
galaxies abundances – ISM abundances – Hii regions
2010/11/11
We suggest an empirical calibration for determination of oxygen and nitrogen abundances and
electron temperature in Hii regions where the [Oii]3727+3729 line (R2) is not available.
The calibration...

IRON ABUNDANCE DETERMINATION FOR THE SOLAR-LIKE STARS HR4345 AND HR6573
Stars abundances - Techniques spectroscopic - Line profiles
2009/3/5
Using the BLACKWELL software package written by R.O. Gray,
the iron abundance of the solar-like stars HR 4345 and HR 6573 has been de-
termined. The method is based on determination of the minimum d...
