Title: Compact stars: between quarks, hadrons, and dark matter
Speaker: Dr. Carline Biesdorf (ITA)
Abstract:
In this seminar, I will explore the mysteries of compact stars and how advanced theoretical models can reveal new possibilities for their internal composition. Starting from the fundamental question — what are the so-called neutron stars actually made of? — I will discuss the hypothesis of quark stars in the context of the Modified MIT Bag Model, developed to describe more realistically the stability and properties of quark matter under extreme conditions, such as those found in these compact objects. Next, I will address hybrid stars, which combine hadronic and quark matter, and how the presence of dark matter may silently reshape their cores, altering the critical mass for the formation of quark cores and concealing their observational signatures. The seminar will show how nuclear physics, astrophysics, and cosmology intertwine in the quest to understand the nature of matter in extreme regimes, highlighting recent contributions and future perspectives.

Title: Conscious Discipline at ITA: A Culture that Shapes
Speakers: Prof. Carmen Belderrain and Prof. Iris de Oliveira Zeli (Working Group on Conscious Discipline, ITA)
Abstract:
This presentation proposes a reflection on Conscious Discipline (CD) as an essential part of ITA’s educational model, adopted since 1955. CD is a culture based on mutual trust, responsibility, integrity, and commitment to the collective. The talk revisits the historical foundations of Conscious Discipline, presenting practical examples and highlighting its continuity and relevance in the 21st century, reinforcing its role in the comprehensive development of individuals — technically, ethically, and humanly. Perceptions from the academic community and initiatives aimed at strengthening this culture in the daily life of the institution will also be shared. The goal is to broaden the shared understanding of Conscious Discipline and encourage its conscious, active, and continuous practice at ITA.
