Welcome to AIfA!
Welcome to the AIfA! The Argelander-Institut für Astronomie (AIfA) is an
academic, research and educational institute that is part of the
Department of Physics and Astronomy at the University of Bonn, Germany.
We conduct cutting-edge research over a broad range of theoretical and
observational topics from stars to cosmology, as you can see from our
Research page. Many national and international collaborations
have partners in the AIfA, for example we have a close relationship with
our neighbour, the Max-Planck Institut fuer Radioastronomie (MPIfR).

The spectroscopic Hertzsprung-Russell diagram of Galactic massive stars
29.10.2014The distribution of stars in the Hertzsprung-Russell diagram narrates their evolutionary history and directly assesses their properties. Placing stars in this diagram however requires the knowledge of their distances and interstellar extinctions, which are often poorly known for Galactic stars. The spectroscopic Hertzsprung-Russell diagram (sHRD) tells similar evolutionary tales, but is independent of distance and extinction measurements.

Spectacular end proposed for the star Betelgeuse
11.08.2014The supergiant star Betelgeuse will soon end its life with a spectacular sequence of interstellar fireworks. This is the result of a new theory developed by astrophysicists from the University of Bonn, published recently in the journal Nature. The star's explosion could be so strong that it could be seen from Earth in the sky during the day. "It could happen tomorrow or in a hundred thousand years," explained Dr. Jonathan Mackey from the University of Bonn, the leader of the International Science team.
