Both accurate and precise gf-values for FeII lines
Jorge Melendez, Beatriz Barbuy
We present a new set of oscillator strengths for 142 FeII lines in the wavelength range 4000-8000 A. Our gf-values are both accurate and precise, because each multiplet was globall…
Metallicities for 13 nearby open clusters from high-resolution spectroscopy of dwarf and giant stars. Stellar metallicity, stellar mass, and giant planets
N. C. Santos, C. Lovis, G. Pace +2
We present a study of accurate stellar parameters and iron abundances for 39 giants and 16 dwarfs in the 13 open clusters IC2714, IC4651, IC4756, NGC2360, NGC2423, NGC2447 (M93), N…
Another forbidden solar oxygen abundance: the [O I] 5577 A line
Jorge Melendez, Martin Asplund
Context: Recent works with improved model atmospheres, line formation, atomic and molecular data, and detailed treatment of blends, have resulted in a significant downward revision…
Chemical abundances in giants stars of the tidally disrupted globular cluster NGC 6712 from high-resolution infrared spectroscopy
David Yong, Jorge Melendez, Katia Cunha +3
We present abundances of C, N, O, F, Na, and Fe in six giant stars of the tidally disrupted globular cluster NGC 6712. The abundances were derived by comparing synthetic spectra wi…
New Extremely Metal-Poor Stars in the Galactic Halo
Judith G. Cohen, Norbert Christlieb, Andrew McWilliam +5
We present a detailed abundance analysis based on high resolution and high signal-to-noise spectra of eight extremely metal poor (EMP) stars with [Fe/H] < -3.5$ dex, four of which…
Magnesium Isotopes in Halo Stars
Jorge Melendez, Judith G. Cohen
We have determined Mg isotope ratios in halo field dwarfs and giants in the globular cluster M71 based on high S/N high spectral resolution (R = 10) Keck HIRES spectra. Unlike…
