DESCRIPTION:Speakers: Pablo Navarro Moreno ()\nWe explore "ridges" in the 
 macroscopic properties of rotating neutron stars as potential indicators o
 f first-order phase transitions in their matter. These phase transitions i
 nduce non-analytic behavior in observables like angular momentum\, moment 
 of inertia\, mass\, and radii\, with the intensity of this behavior direct
 ly tied to the latent heat of the transition. Notably\, the Seidov limit s
 ets a bound on the maximum latent heat a phase transition can produce befo
 re its excess energy density\, not compensated by additional pressure\, re
 sults in gravitational collapse.\n\nAdditionally\, we investigate how modi
 fied gravity theories\, such as quadratic f(R) gravity\, affect these phen
 omena. In this context\, we find that the Seidov limit undergoes substanti
 al modification compared to General Relativity. Breaching the Seidov limit
  would lead to two significant discoveries: evidence of a first-order phas
 e transition in neutron star matter and a deviation from General Relativit
 y.\n\nBased on Annals Phys. 459 (2023) 169487\, 2307.15366 and arXiv:2409.
