Neutron stars as laboratories for testing extreme gravity
Due to their high compactness and strong gravitational field, neutron stars offer us natural astrophysical laboratories to test extrem

I will discuss new degrees of freedom of gravity as motivated by string theory. Although they are expected to be generically quantum mechanical, classes of such states are coherent enough to admit classical descriptions in Einstein gravity. I will explain how to describe them as novel ultra-compact geometries without horizon or singularity.
The "New horizons for Psi school and workshop" will take place at IST Lisbon, 1-5 July 2024, with the participation of Gr@v members as speakers.
C. Herdeiro gave an invited colloquium at the Institutt for teoretisk astrofysikk of the University of Oslo Norway on September 1st 2023.
The paper "Two spinning black holes balanced by their synchronised scalar hair", describing the first construction of two asymptotically flat, neutral, spinning black holes in equilibrium, regular on and outside their event horizon, supported by their "hair", was published in Physical Review Letters and highlighted as Editors' Suggestion.
