Exploring the History of Stellar Mergers with Chemistry: Examining the Origins of Massive -Enriched Stars using Carbon Isotope Ratios
Zachary G. Maas, Keith Hawkins, Jeffrey M. Gerber +2
Recently discovered massive -enriched (MAE) stars have surface chemistry consistent with members of the older thick disk Milky Way population but high masses ( 1.5 - 3 M$_…
NLTE abundances of Eu for a sample of metal-poor stars in the Galactic Halo and Metal-poor Disk with 1D and <3D> models
Yanjun Guo, Nicholas Storm, Maria Bergemann +6
Accurate measurements of europium abundances in cool stars are essential for an enhanced understanding of the r-process mechanisms. We measure the abundance of Eu in solar spectra…
Non-LTE Radiative Transfer with Turbospectrum
Jeffrey M. Gerber, Ekaterina Magg, Bertrand Plez +4
Physically realistic models of stellar spectra are needed in a variety of astronomical studies, from the analysis of fundamental stellar parameters, to studies of exoplanets and st…
Observational constraints on the origin of the elements. IV: The standard composition of the Sun
Ekaterina Magg, Maria Bergemann, Aldo Serenelli +11
The chemical composition of the Sun is requested in the context of various studies in astrophysics, among them in the calculation of the standard solar models (SSMs), which describ…
The SAPP pipeline for the determination of stellar abundances and atmospheric parameters of stars in the core program of the PLATO mission
Matthew Raymond Gent, Maria Bergemann, Aldo Serenelli +25
We introduce the SAPP (Stellar Abundances and atmospheric Parameters Pipeline), the prototype of the code that will be used to determine parameters of stars observed within the cor…
Light Element Abundances and Multiple Populations in M53
Jeffrey M. Gerber, Eileen D. Friel, Enrico Vesperini
We present results from a study of 94 red giant stars in the globular cluster M53. We use low-resolution spectra to measure the strength of CN and CH features at 3800 and 430…
