Four Cold Giant Planets Discovered by High-Cadence Microlensing Surveys

Discovery Background

High-cadence microlensing surveys have discovered four giant planets. The planets orbit stars with masses between 7% and 60% of the Sun's mass.

Observation Details

All the planets appear to lie beyond the snow lines of their hosts. This could help understand the formation and evolution of the planets.

Scientific Significance

Comparing the discovered planets with those in our solar system could help test planet formation theories. Additionally, this discovery could open a new chapter in exoplanet research.
