Phase transitions are ubiquitous in physics, and their manifestation in the scalarization of compact objects provides a rich ground for theoretical exploration. Following the recent discovery that scalarization in neutron stars typically constitutes a first-order phase transition, we extend this analysis to other compact objects, including boson stars and black holes. By employing a Landau-theory-inspired approach combined with phase diagram analysis, we investigate the nature of phase transitions during the scalarization of these compact objects. Our analysis reveals a complex phase structure where distinct mechanisms can lead to markedly different evolutionary paths for these astrophysical systems.
