and extra-solar planets


Kepler-10b fik i sin tid kælenavnet 'Vulcan', da astrofysikerne mener, at planeten har et stort lavahav på den side, der vender ind mod planetens stjerne. Det er det planetsystem, som Alexandra Fogtmann-Schulz nu har fundet ny viden om. (Ill: NASA)

Natten ulmer på lavaplanet (article in Danish only)

En fysikstuderendes bachelorprojekt har givet langt dybere indsigt i et planetsystem og afsløret en overraskelse om en planet, forskerne troede, de ”kendte”.

For the last twenty years, astronomers have been searching for exoplanets – without yet finding an ‘Earth 2’. The main objective of the new PLATO space mission is to find ‘Earth 2’. (illustration: NASA)

New space mission to search for ‘Earth 2’

The European Space Agency (ESA) has just decided to build the PLATO satellite, planned for launch in 2024. PLATO will begin a detailed search for planets orbiting alien stars. Aarhus University researchers will play an active role in the PLATO mission.

Aarhus scientists find new planet

Using data from the Kepler satellite, a team of researchers at Aarhus University has pinpointed yet another exoplanet. The planet is the size of Neptune and is located in orbit around a star in a double-star system 425 light years from the Earth.

New professor hunts planets and listens to the stars

Hans Kjeldsen has been appointed Professor of Observational Asteroseismology and Exoplanet Studies at the Department of Physics and Astronomy, Aarhus University. The aim of his research is to understand the stars, their interiors, their surroundings and activity, and their planetary systems.

Disorderly planetary system challenges the theories

The planets orbiting our own Sun do so in an orderly system. Rocky planets are on the inside, while the gas giants – including Jupiter – are on the outside, and all the trajectories follow virtually the same plane. This is how it most often commonly takes place, according to the astronomers’ theories for planet formation. However, a newly…
