Astronomers studying a dim red dwarf star called LHS 1903 have found a four-planet system with an architecture that defies the standard rules of how rocky worlds take shape. The outermost planet in ...

The binary star system ν Octantis has long been considered hostile to planet formation. The discovery of a white dwarf in the system offers an alternative view. However, Cheng and colleagues observe ...

Two of the objects in the arrangement are cold brown dwarfs, which will serve as a benchmark for others throughout the Milky Way. By Katrina Miller Zenghua Zhang, an astronomer at Nanjing University ...

One of the longest stellar dimming events ever observed was likely caused by the gigantic saucer-like rings of either an unseen brown dwarf or "super-Jupiter" blocking its host star's light, ...

Add Yahoo as a preferred source to see more of our stories on Google. Red dwarfs dominate the neighborhood and often host rocky worlds in temperate orbits. Yet their environments may hinder complex ...

How did this red dwarf star 240 light-years away end up with a gas giant planet? Credit: University of Warwick / Mark Garlick illustration Astronomers have discovered a world outside the solar system ...

What can exoplanets orbiting M-dwarf stars teach scientists about planetary formation and evolution? This is what a recent study posted to the arXiv preprint server and submitted to the American ...

Scientists have discovered a giant planet orbiting a tiny red dwarf star, something they believed wasn t even possible. The planet, TOI-6894b, is about the size of Saturn but orbits a star just a ...

Many of the stars in the Milky Way galaxy are small, dim red dwarfs—stars much smaller than the sun in both size and mass. TOI-6894, located far away from Earth, is one of them. Astronomers previously ...

Figure1: Infrared image showing the directly imaged brown dwarf companion J1446B (dot indicated by the arrow). The central red dwarf (J1446) is masked in white during image processing. The scale bar ...
