Benchmark Brown Dwarf Systems I: Chemical Abundance Analysis of FGK Stars with Wide-Separation Brown Dwarf Companions Using PEPSI
Caprice L. Phillips, Megan Bedell, Catherine Manea +11
We present results from a spectroscopic survey of 32 FGK stars hosting brown dwarfs, using high-resolution optical spectra (R = 130,000 and 50,000) obtained with the PEPSI spectrog…
Untangling the Sources of Abundance Dispersion in Low-metallicity Stars II: Neutron Capture Elements
Emily J. Griffith, Marissa Blum, David H. Weinberg +4
We present the abundances of 23 elements, including 11 heavy elements (Cu, Zn, Sr, Y, Zr, Ba, La, Ce, Nd, Sm, Eu) for up to 86 metal-poor (-2 < [Fe/H] < -1) subgiants. We use KORG,…
Retrieving Young Cloudy L-Dwarfs: A Nearby Planetary-Mass Companion BD+60 1417B and Its Isolated Red Twin W0047
Caprice L. Phillips, Jacqueline K. Faherty, Ben Burningham +11
We present an atmospheric retrieval analysis on a set of young, cloudy, red L-dwarfs -- CWISER J124332.12+600126.2 and WISEP J004701.06+680352.1 -- using the \textit{Brewster} retr…
Spectacular nucleosynthesis from early massive stars
Alexander P. Ji, Sanjana Curtis, Nicholas Storm +39
Stars formed with initial mass over 50 Msun are very rare today, but they are thought to be more common in the early universe. The fates of those early, metal-poor, massive stars a…
The Impact of Black Hole Formation on Population Averaged Supernova Yields
Emily J. Griffith, Tuguldur Sukhbold, David H. Weinberg +3
The landscape of black hole (BH) formation -- which massive stars explode as core-collapse supernovae (CCSN) and which implode to BHs -- profoundly affects the IMF-averaged nucleos…
The Similarity of Abundance Ratio Trends and Nucleosynthetic Patterns in the Milky Way Disk and Bulge
Emily Griffith, David H. Weinberg, Jennifer A. Johnson +9
We compare abundance ratio trends in a sample of Milky Way bulge stars ( kpc) from the Apache Point Observatory Galactic Evolution Experiment (APOGEE)…
Abundance ratios in GALAH DR2 and their implications for nucleosynthesis
Emily Griffith, Jennifer A. Johnson, David H. Weinberg
Using a sample of 70 924 stars from the second data release of the GALAH optical spectroscopic survey, we construct median sequences of [X/Mg] vs. [Mg/H] for 21 elements, separatin…
