Astronomers spot an "inside-out" exoplanet system that defies models
Astronomers studying a faint red dwarf star called LHS 1903 have found a four-planet system arranged in a sequence that no standard model of planet formation predicted. The system follows a ...
Add Yahoo as a preferred source to see more of our stories on Google. An artist's impression of a planetary system with four planets, around a small red star, called LHS1903 with a large reddish-brown ...
Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands ...
‘Star Wars’ predicted it: Planet discovered that orbits two suns like Luke Skywalker’s home Tatooine
Is it a two-for-sun deal. Astronomers were blown away after discovering a bizarre exoplanet that orbits twin stars closer than any ever seen before in a binary star system, per a starry study ...
Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...
As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether. Smaller ...
