Stellar physics

The stars are the main building blocks of the visible universe. The stars act as thermonuclear reactors in which all chemical elements heavier than hydrogen and helium are synthesized.

The astronomers of the Tartu Observatory study different types of stars, both observationally and theoretically.

    Astronomy seminar

    The cosmic web is vital for studying dark matter and the cosmological model and understanding galaxy evolution. However, detecting the cosmic web from observations is a complex task.
