DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CENTRA/22/">
 Onset of spontaneous scalarization in generalized scalar-tensor theories</
 a>\nby Antoine Lehebel (CENTRA\, IST) as part of CENTRA Seminar\n\n\nAbstr
 act\nSpontaneous scalarization is a mechanism that endows relativistic sta
 rs and black holes with a nontrivial configuration only when their spaceti
 me curvature exceeds some threshold. Beyond this threshold\, they acquire 
 a nontrivial scalar configuration\, which also affects their structure. Th
 e onset of scalarization is controlled only by terms that contribute to li
 near perturbation around solutions of general relativity. I will present t
 he complete set of these terms in generalized scalar-tensor theories\, and
  determine the relevant thresholds in terms of the contributing coupling c
 onstants and the properties of the compact object.\n
