What Are Mira Variable Stars? - Physics Frontier

Описание: What Are Mira Variable Stars? In this informative video, we will take a closer look at Mira variable stars, a captivating type of pulsating red giants. These stars are in the later stages of their life cycle and exhibit remarkable changes in brightness over time. We will discuss their unique properties, including their long pulsation periods and how they can shine thousands of times brighter than our Sun despite being less massive.

You'll learn about the fascinating processes that occur within these stars, including the expansion and contraction of their outer layers, which leads to variations in size and temperature. We will also explore how these changes influence their brightness and the relationship between pulsation periods and luminosity.

Additionally, we will highlight the significance of Mira variables in variable star studies and how their brightness changes can be used to measure distances in astrophysics. We will touch on the methods astronomers use to observe these stars and the advancements in imaging techniques that have enhanced our understanding of their complex atmospheres.
