Mass ratio M_max/M_TOV vs. M_TOV for an ensemble of hybrid EoSs from Jokela et al. (2020). The colored markers show the results for different low-density nuclear matter models, indicated in the legend, as the matching density n_tr varies. Triangles, squares, and diamonds use soft, intermediate, and stiff versions of the holographic model, respectively. The filled (open) markers are EoSs for which the Keplerian curve reaches (fails to reach) the GW190814 band in Figure 4. The EoSs used in the other figures are shown with large black open markers. The green, blue, and red bands show the estimates for the mass ratio (Breu & Rezzolla 2016), minimum of M_TOV based on GW190814 (Most et al. 2020), and maximum of M_TOV (Rezzolla et al. 2018), respectively. The horizontal black line shows our fit result from (3).
