Exploring the diversity of extrasolar planets
About SPP 1992 Exoplanet Diversity
The SPP 1992 is a Priority Program funded by the Deutsche Forschungsgemeinschaft. It deals with the diversity and complexity of exoplanets by combining observational methods for the detection and characterization of planets with theory and modelling.
Exoplanet systems
The planets of our Solar System are ordered a certain way: closest to the sun are the smaller, terrestrial planets Mercury, Venus, Earth and Mars, then..
...
Astrometry
Like the radial velocity method, this technique makes use of the fact that star and planet both orbit a shared center of mass
...
Direct Imaging
Exoplanets are so faint and far away that they are almost invisible even to powerful telescopes
...
Gravitational lensing
The Einstein ring is a ring of electromagnetic radiation from a distant object, created by the gravitational effect of a galaxy in the foreground
...
Transit method
The most common methods for finding exoplanets are transit and radial velocity
