Rp attractors static neutron star phenomenology

VK Oikonomou - Monthly Notices of the Royal Astronomical …, 2023 - academic.oup.com
In this work, we study the neutron star phenomenology of R p attractor theories in the
Einstein frame. The Einstein frame R p attractor theories have the attractor property that they …

Inflationary attractors predictions for static neutron stars in the mass-gap region

SD Odintsov, VK Oikonomou - Physical Review D, 2023 - APS
