Abundance Analysis of Stars at Large Radius in the Sextans Dwarf Spheroidal Galaxy

Abundance Analysis of Stars at Large Radius in the Sextans Dwarf Spheroidal Galaxy

We present the stellar parameters and chemical abundances of 30 elements for five stars located at large radii (3.5–10.7 times the half-light radius) in the Sextans dwarf spheroidal galaxy. We selected these stars using proper motions, radial velocities, and metallicities, and we confirm them as met...
