Cold Jupiters often hide hot super-Earths in their inner orbits

Star system: HD 50554 | Distance from the Sun: 102 light years

A statistical analysis of 132 planetary systems reveals a strong architectural link between giant outer planets and smaller inner worlds. Researchers found that stars hosting a 'cold Jupiter'—a gas giant orbiting far from its sun—are significantly more likely to also host 'hot super-Earths' in close-in orbits. 

The study suggests that approximately 87% of these giant planet systems also contain at least one smaller rocky planet closer to the star. This discovery, supported by data from the TESS space telescope and ground-based radial velocity measurements, provides key evidence that the formation of massive gas giants does not prevent, but rather often accompanies, the creation of smaller terrestrial planets.
