Metal-poor accreted star cand. abund.

We find that while age determination is highly dependent on the log g and asteroseismic information used, the overall chemical abundance distributions are similar for different logg. However, we find that calcium (Ca) abundances are more sensitive to the adopted logg. Our study reveals that the majority of our stars have properties that are compatible with those reported for the Gaia-Sausage-Enceladus, with a minority of stars that might be associated with Splash.

We find an age distribution with a median of 11.3Gyr when including asteroseismic information. Regarding some key chemical signatures, we note that these stars are metal poor ([Fe/H])<-0.8), {alpha} rich ([{alpha}]/Fe]>0.2), and copper poor ([Cu/Fe]<0 ), with chemical abundances typical of accreted stars. These findings illustrate the importance of multidimensional analyses in unraveling the complex accretion history of the Milky Way.
