An EOS-Driven Extension of NSCool for Compact Star Cooling with Hadronic and Quark Degrees of Freedom
Federico Nola, Fernando Arias-Aragón
We present an EOS-driven extension of the NSCool thermal evolution code that enables complete tabulated equations of state to be treated within a single composition-based input str…
Trace Anomaly and Effective Topological Sources in Neutron Stars
Federico Nola
This work investigates whether the trace anomaly can diagnose the stellar response to a topological scalar field in tensor multi-scalar gravity. Eleven cold tabulated equations of…
Core Composition Effects on the QCD Axion Mass Limit from Neutron Star Cooling
Fernando Arias-Aragón, Federico Nola
Neutron stars are very dense media in which axions may be produced. This has been used to set limit on the QCD axion mass, usually under the assumption that only neutrons, protons,…
NICER Constraints on Low density Interpolation and High density Continuation in Neutron Star Equations of State
Federico Nola
We investigate whether current astrophysical data constrain not only the high density continuation of the neutron star equation of state, but also the low density matching procedur…
From EFT to Multi-Region Modeling: Neutron star structure with a polytropic extension of EFT and MUSES Calculation Engine multi-layer modeling
Federico Nola
Neutron stars provide a unique environment to probe the properties of dense nuclear matter. In this work, we present a comparative study between two approaches to modeling the neut…
Experimental exclusion of a generalized Károlyházy gravity-induced decoherence model
Nicola Bortolotti, Kristian Piscicchia, Matthias Laubenstein +4
We report new experimental constraints on the generalized version of the gravity-induced decoherence model originally proposed by Károlyházy. Using data collected by the VIP Collab…
