Special star is a Rosetta Stone for understanding the sun’s variability and climate effect


(Aarhus University) A large international team of scientists has found a star that can help shed light on the physics underlying the solar dynamo. The team has combined observations from the Kepler spacecraft with ground-based observations as far back as 1978, thereby reconstructing a 7.4-year cycle in this star. The star is almost identical to the Sun, except for the chemical composition. That makes it a Rosetta Stone for the study of stellar dynamos. ……Read More…….
