WebThe age of star clusters can be estimated by examining a plot of star brightness (magnitude) against colour (temperature), this plot is known as a H-R diagram. Below are a few examples and variations of these plots. The H-R diagram plot is used to reveal which stars are still on the main sequence - since we are able to easily identify how long ...

How do scientists determine the age of stars?

WebFigure 1. Young Cluster H–R Diagram: We see an H–R diagram for a hypothetical young cluster with an age of 3 million years. Note that the high-mass (high-luminosity) stars have already arrived at the main-sequence stage of their lives, while the lower-mass (lower-luminosity) stars are still contracting toward the zero-age main sequence (the red line) … WebNov 25, 2024 · In fact, new work suggests that its many young stars formed in three distinct waves, over just a few million years.
