In this video, the stars in globular cluster Omega Centauri are rearranged according to their intrinsic brightness (vertical axis) and their temperature (horizontal axis). The temperature of a star dictates its apparent colour, with cooler stars being red and hotter ones being blue.

WebAstronomers use the Hertzsprung-Russell diagram to trace the evolutionary stage of a star. The Hertzsprung diagram where the evolution of sun-like stars is traced. Credits:ESO. This is a plot of temperature versus brightness, and as stars are born, live and die, they move in regular patterns around the Hertzsprung-Rusell diagram. WebOct 7, 2024 · You can use an HR diagram along with calibrated evolutionary models to find the distance (and in some cases, mass and age) of individual stars. The method is known as spectroscopic parallax.This is a confusing name because it is not a parallax measurement at all. The technique is to use spectroscopy, or less precisely the colours, of a star to … cls exchange
