Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers from the Universities of Bern and Geneva, as well as from the National Centre of Competence in Research PlanetS, have now shown for the first time that there are in fact four typ
and the National Centre of Competence in Research PlanetS show that our planetary system is quite unique in this respect.“More than a decade ago, astronomers noticed, based on observations with the then-groundbreaking Kepler telescope, that planets in other systems usually resemble their respective neighbors in size and mass – like peas in a pod,” says study lead author Lokesh Mishra, researcher at theand Geneva, as well as the NCCR PlanetS.
Artist impression of the four classes of planetary system architecture. A new architecture framework allows researchers to study an entire planetary system at the systems level. If the small planets within a system are close to the star and massive planets further away, such systems have ‘Ordered’ architecture. Conversely, if the mass of the planets in a system tends to decrease with distance to the star these systems are ‘Anti-Ordered’.
“This framework can also be applied to any other measurements, such as radius, density or water fractions,” says study co-author Yann Alibert, Professor of Planetary Science at the University of Bern and the NCCR PlanetS. “Now, for the first time, we have a tool to study planetary systems as a whole and compare them with other systems.”
