A Puzzle Involving Galactic Bulge Microlensing Events

Judith G. Cohen, Andrew Gould, Ian B. Thompson +7

We study a sample of 16 microlensed Galactic bulge main sequence turnoff region stars for which high dispersion spectra have been obtained with detailed abundance analyses. We demo…

Does the anomalous solar chemical composition come from planet formation?

I. Ramirez, J. Melendez, M. Asplund

We derive the abundance of 19 elements in a sample of 64 stars with fundamental parameters very similar to solar, which minimizes the impact of systematic errors in our spectroscop…

The solar, exoplanet and cosmological lithium problems

J. Melendez, I. Ramirez, L. Casagrande +6

We review three Li problems. First, the Li problem in the Sun, for which some previous studies have argued that it may be Li-poor compared to other Suns. Second, we discuss the Li…

Chemical abundances for 11 bulge stars from high-resolution, near-IR spectra

N. Ryde, B. Gustafsson, B. Edvardsson +10

It is debated whether the Milky Way bulge has the characteristics of a classical bulge sooner than those of a pseudobulge. Detailed abundance studies of bulge stars is a key to inv…

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…
