Scientists have recently unveiled a new way to measure the masses of RR Lyrae stars, a type of variable star found in the Milky Way. Using the new approach, they have been able to accurately measure the masses of two RR Lyrae stars, which were previously difficult to calculate. This new method could help us better understand the structure and evolution of galaxies.

Varible stars, like RR Lyrae stars, are stars that pulsate in brightness. By studying these stars, astronomers have been able to gain insights into the structure and evolution of galaxies. Until now, however, it has been difficult to accurately measure the masses of these stars.

However, scientists have now unveiled a new approach to calculate the masses of RR Lyrae stars. By combining the observations of two RR Lyrae stars, the team was able to accurately measure their masses. This new method could potentially be used to measure the masses of other variable stars as well, which could give us a better understanding of the structure and evolution of galaxies.
