Chemical separation of stellar populations: analytic solutions for chemical evolution models with metallicity-dependent yields
Jason L. Sanders
Stellar abundances of elements with production channels that are metallicity-dependent (most notably aluminium) have provided an empirical route for separating different Galactic c…

Carbon-Enhanced Dwarf Stars Are Predominantly a Halo Population
Jay Farihi, Jason L. Sanders, Sophia Lilleengen +2
This paper reports a Galactic kinematical and dynamical analysis of 1003 main-sequence carbon stars. The sample is drawn from the Sloan Digital Sky Survey, and cross-matched with G…

Stellar streams from black hole-rich star clusters
Daniel Roberts, Mark Gieles, Denis Erkal +1
Nearly a hundred progenitor-less, thin stellar streams have been discovered in the Milky Way, thanks to Gaia and related surveys. Most streams are believed to have formed from star…
