      abstract     = {We study the impact of state-of-the-art top-quark data
                      collected at the large hadron collider on parton
                      distribution functions (PDFs). Following the ABMP
                      methodology, the fit extracts simultaneously proton PDFs,
                      the strong coupling $\alpha _s(M_Z)$ and heavy-quark masses
                      at next-to-next-to-leading order (NNLO) accuracy in QCD. It
                      includes recent high-statistics data on absolute total
                      inclusive cross sections for $t\bar{t}+X$, the sum of $(t +
                      X)$ and $(\bar{t} + X)$ hadroproduction, and normalized
                      inclusive data double-differential in the invariant mass and
                      rapidity of the $t\bar{t}$ pair at $\sqrt{S}=13$ TeV. The
                      gluon PDF at large x and the top-quark mass value derived
                      from these data are well compatible with the previous ABMP16
                      results, but with significantly smaller uncertainties,
                      reduced by up to a factor of two. At NNLO in QCD we obtain
                      for the strong coupling the value $\alpha _s^{(n_f=5)}(M_Z)=
                      0.1150 \pm 0.0009$ and for the top-quark mass in the
                      ${\overline{\text{ MS }}}$-scheme $m_t(m_t) = 160.6 \pm 0.6$
                      GeV, corresponding to $m_t^\textrm{pole} = 170.2 \pm 0.7$
                      GeV in the on-shell scheme. The new fit, dubbed ABMPtt, is
