New model could ultimately tell age of stars precisely
By looking at the physics behind the speeding up or slowing down of a stars rotation, its x-ray activity, and magnetic field generation, researchers have developed a new conceptual framework for understanding how stars similar to our Sun evolve.
New York: By looking at the physics behind the speeding up or slowing down of a stars rotation, its x-ray activity, and magnetic field generation, researchers have developed a new conceptual framework for understanding how stars similar to our Sun evolve.
The work could "ultimately help to determine the age of stars more precisely than is currently possible", said study first author Eric Blackman, professor of physics and astronomy at the University of Rochester in New York, US.The new model, published in the journal Monthly Notices of the Royal Astronomical Society,
helps explain how stellar rotation, activity, magnetic field, and mass loss all mutually evolve with age, the researchers explained. Using our Sun as the calibration point, the model accurately described the likely behaviour of the Sun in the past, and how it would be expected to behave in the future.
