Course Content


Astrophysical Units and Magnitude Scale

  • Introduction to standard units of measurement in astrophysics.
  • Detailed study of the magnitude scale and its applications.

Stellar Structure and Evolution

  • Introduction to the Hertzsprung–Russell (HR) diagram and its importance in stellar classification.
  • In-depth analysis of the equations governing stellar structure.
  • Evolutionary paths of stars, including stages on and beyond the main sequence.
  • Introduction to compact objects such as white dwarfs, neutron stars, and black holes.
  • Binary systems: observational properties, types (visual, spectroscopic, eclipsing), and their role in astrophysical measurements.

Exoplanets

  • Exoplanets: properties and detection techniques (transits, radial velocity, direct imaging, microlensing).
  • Overview of planetary system architectures and habitability criteria.

Properties of the Interstellar Medium (ISM)

  • Processes involved in star formation.
  • Characteristics and dynamics of H II regions.
  • Mechanisms and implications of supernova explosions.

Dynamics of Stellar Systems

  • Study of the formation, structure, and evolution of star clusters.
  • Dynamics and morphology of galaxies.



Obiettivi formativi

Upon successful completion of this course, students will:


  • Understand and use astrophysical units and measures to the level of a junior researcher.
  • Become acquainted with the latest results and open questions in astrophysical research.
  • Obtain theoretical tools for evaluating the structural and evolutionary properties of stars.
  • Understand the physical processes governing the interstellar medium through an introduction in astrophysical fluid mechanics.
  • Evaluate the dynamics of stellar systems through theoretical and observational frameworks.
