These collisions produce shocks and accelerating electrons, leading to varying X-ray intensity based on the stars' orbits....

For instance, in Gliese 1183, star A has stronger X-ray and Hα emissions than B, despite similar rotation speeds....

This planet is smaller than Earth and orbits its star in just 3.15 days....

The star TOI-5005 is bright, making it ideal for further study. The ridge is densely populated with Neptune-sized exoplanets, unlike the desert and savanna regions, where only few were found....

James Webb detected quartz in the atmosphere of exoplanet HD 189733 b. Hot Jupiter HD 189733 b orbits a nearby star HD 189733 that is smaller than the Sun and lies only 64 light years away. The planet orbits close to the star with period only 2.2 days. The temperature in its atmosphere rises to scorching 1000 °C....

This process could explain the existence of LHS 3154 b....

Exoplanets Kepler 186 f and TOI 700 d might have magnetic fields sufficiently strong to protect their atmospheres and surfaces from stellar magnetic fields....

One of the stars, TOI-4914 b, is more inflated than what is supported by current theoretical models. Warm Jupiter TOI 4914 b has about 70 % of Jupiter's mass, but its radius is 15 % bigger. That gives it about half of Jupiter's density....

This newly found exoplanet TOI 4562 c has the longest orbital period of any planet discovered via transit timing variations....
