We measured phosphorus abundances in 22 FGK dwarfs and giants that span −0.55 < [Fe/H] 0.2 using spectra obtained with the Phoenix high-resolution infrared spectrometer on the Kitt Peak National Observatory Mayall 4 m telescope, the Gemini South Telescope, and the Arcturus spectral atlas. We fit synthetic spectra to the P i feature at 10581 Å to determine abundances for our sample. Our results are consistent with previously measured phosphorus abundances; the average [P/Fe] ratio measured in…

Phosphorus Abundances in the Hyades and Galactic Disk
We have measured phosphorus abundances in nine disk stars between −1 < [Fe/H] < –0.5 and in 12 members of the Hyades open cluster using two P I lines at 1.06 μm. High-resolution infrared spectra were
The Galactic Distribution of Phosphorus: A Survey of 163 Disk and Halo Stars
Phosphorus (P) is a critical element for life on Earth, yet the cosmic production sites of P are relatively uncertain. To understand how P has evolved in the solar neighborhood, we measured
Fluorine in the solar neighborhood : Chemical evolution models
Context. In light of new observational data related to fluorine abundances in solar neighborhood stars, we present chemical evolution models testing various fluorine nucleosynthesis prescriptions

We have derived elemental abundances of three field red horizontal branch stars using high-resolution (R ≃ 45,000), high signal-to-noise ratio (S/N ≳ 200) H- and K-band spectra obtained with the
APOGEE Data Releases 13 and 14: Stellar Parameter and Abundance Comparisons with Independent Analyses
Data from the SDSS-IV/Apache Point Observatory Galactic Evolution Experiment (APOGEE-2) have been released as part of SDSS Data Releases 13 (DR13) and 14 (DR14). These include high-resolution H-band
Chemical evolution with rotating massive star yields - I. The solar neighbourhood and the s-process elements
We present a comprehensive study of the abundance evolution of the elements from H to U in the Milky Way halo and local disk. We use a consistent chemical evolution model, metallicity dependent
The APOGEE Data Release 16 Spectral Line List
The updated H-band spectral-line list (from λ15000–17000) adopted by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) for the SDSS-IV Data Release 16 (DR16) is presented in this
The first steps of interstellar phosphorus chemistry
Context. Phosphorus-bearing species are essential to the formation of life on Earth, however they have barely been detected in the interstellar medium. In particular, towards star-forming regions
The origin of elements: the need for UV spectra
Thanks to the long-term collaborations between nuclear and astrophysics, we have good understanding on stellar nucleosynthesis, except for the elements around Ti and some neutron-capture elements.
