Then, they split these stars into two batches: one containing 369 stars that rotate every 20 to 30 days and one with 2,529 stars that scientists haven't been able to calculate a rotation period ...
Once they’d done that, only HD 162826 made the cut. It’s not a twin of the Sun: HD 162826 is about 15% more massive than our home star. That’s no surprise, however since a given molecular ...
Close stellar encounters could change the structure of our planetary system, potentially dooming Earth or other worlds to ...
Is our sun fundamentally different from other "sun-like" stars? This question highlights an ongoing controversy about whether our nearest star is unique or, in fact, an "ordinary star." ...
Astronomers have uncovered what appear to be 21 neutron stars in orbit around stars like our Sun. ... Black holes, for example, are often found orbiting each other.
Accepted wisdom holds that the Sun is an ordinary, run-of-the-mill star. ... Typical solar cycles last about 11 years, but the strength of each cycle varies considerably.
