The intrinsic dispersion of elemental abundance ratios in nearby metal-poor halo stars

Poul Erik Nissen, Anish Amarsi

Differential abundances of C, O, Mg, Al, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Y, and Zr were determined from high signal-to-noise VLT/UVES spectra for 25 turnoff stars with -2.4…
