    Information

    Aims, contents and method of the course

    The variety in multiple star systems is nearly as rich as in the galaxy’s stellar population. These pairs can differ significantly in mass, metallicity, and age. Some binary partners evolve rapidly into red giants or supergiant stars, while their low-mass companions remain stable. Binary systems can also host orbiting planets. And from our viewpoint on Earth, some binary stars stage their eclipses. Eclipses are scientifically valuable because observing changes in light as one star passes in front of the other can reveal their masses, diameters, precise orbits, and even compositions. Pairs of neutron stars can spiral together and collide, producing some of the universe’s heavy elements.

    In this course, we will study the following topics:
    - Classification
    - Statistics
    - Formation and evolution
    - Photometric and spectroscopic observations
    - Planets in multiple systems
    - Orbital and astrophysical parameter determinations
    - Multiple systems and the Gaia database
    - Testing theories (including MOND) with multiple systems
    - Symbiotic, X-ray and high-mass binaries
