Exoplanets

The exoplanet research group at DTU Space focuses on understanding and characterizing exoplanets.

DTU Space has established an exoplanet research group at DTU Space.

The research focuses on understanding and characterizing exoplanets with emphasis on terrestrial planets, super-Earths, and sub-Neptunes.

This is done through two key areas of research:

  • Discovery, validation, and precise mass measurements of transiting and non-transiting planets to understand their composition and structure.
  • Observation, characterization and modelling of exoplanetary atmospheres. 

 

Since the first confirmation of an exoplanet orbiting a sun-like star in 1995, and with only a few, narrow slices of our Milky Way galaxy so far surveyed, many have now been discovered. A recent statistical estimate places, on average, at least one planet around every star in the galaxy. That means there is something on the order of a trillion planets in our galaxy alone, many of them in Earth’s size range.

But there is still a huge job to be done in finding, understanding and characterizing them and to identify the most interesting candidates to investigate further.

The overall aim of our research at DTU Space is to advance our insight into the diversity and composition of the abundant small planets and to pave the way for biosignature observations.
