Spectral model for PB 3877

We have calculated a composite binary spectral model for PB 3877 (J1211+1437), a hyper-velocity subdwarf binary with a cool companion. This work was published in The Astrophysical Journal Letters by Németh et al. (2016, ApJ 821, 13). The figure below shows our spectral decomposition of a Keck/ESI observation.
