"I'll Finish It This Week" And Other Lies
Kaley Brauer
A small group of postdocs, graduate students, and undergraduates inadvertently formed a longitudinal study contrasting expected productivity levels with actual productivity levels.…
R-process-rich stellar streams in the Milky Way
Maude Gull, Anna Frebel, Karina Hinojosa +3
We present high-resolution Magellan/MIKE spectra of 22 bright () metal-poor stars ($-3.18<\mbox{[Fe/H]}<-1.37$) in three different stellar streams, the Helmi debris strea…
Collapsar R-Process Yields Can Reproduce [Eu/Fe] Abundance Scatter in Metal-Poor Stars
Kaley Brauer, Alexander P. Ji, Maria R. Drout +1
It is unclear if neutron star mergers can explain the observed r-process abundances of metal-poor stars. Collapsars, defined here as rotating massive stars whose collapse results i…
The Origin of r-process Enhanced Metal-Poor Halo Stars In Now-Destroyed Ultra-Faint Dwarf Galaxies
Kaley Brauer, Alexander P. Ji, Anna Frebel +3
The highly r-process enhanced (r-II) metal-poor halo stars we observe today could play a key role in understanding early ultra-faint dwarf galaxies, the smallest building blocks of…
