Supertierras

Una Supertierra es un planeta rocoso más masivo que nuestra Tierra pero más ligero que el gigante helado Neptuno. Imagínalo como el "hermano mayor" de la Tierra, con una superficie sólida y, a menudo, una atmósfera densa. Mientras que la Tierra es el planeta terrestre más grande de nuestro sistema solar, las Supertierras llenan el vacío de tamaño entre nosotros y los gigantes gaseosos. Este tipo de planeta no existe en nuestra vecindad, lo que los convierte en objetivos fascinantes para buscar mundos habitables.

Transit timing variations occur when a planet crosses in front of its host star at slightly different times than expected. These small shifts provide information about the orbital path of a planet and the presence of other gravitational forces in the system. By measuring these variations, observers can understand the dynamics and evolution of distant planetary systems. The James Webb Space Telescope provides the high-precision data necessary to track these subtle events across a wide range of...

Image: Orbital and atmospheric evolution of the mini-Neptune TOI-2257 b
The exoplanet TOI-2257 b orbits its star once every 35 days with a high eccentricity. New models suggest its atmospheric and orbital fate depends on whether it is a gas-rich mini-Neptune or a rocky super-Earth. Higher eccentricity would confirm a gaseous nature....

New study characterizes the three-planet system K2-233. The 400 million year old orange dwarf hosts inner iron-rich planets and an outer planet, K2-233 d, that is actively losing its atmosphere. Over time, K2-233 d will likely become a sub-Neptune or super-Earth....
