[Sr/Ba] vs. [Ba/H] for normal metal-poor stars (black dots) following (Andrievsky et al. 2011), and CEMP stars following Frebel (2010) and Cescutti & Chiappini (2013). Green filled circles represent CMP-no stars, open red squares CMP-s stars, and open magenta circles CMP-rs stars. The red dots represent SDSS J111407+182831 and SDSS J1143+2020. In case of mass transfer from an AGB companion [Sr/Ba] < −0.4 (dashed line). Our stars fulfill this requirement.
