This plot makes a Hertzsprung-Russell diagram that shows the main luminosity classes as well as radius and colour for each object. In the first three samples the selected stars had parallaxes ten ...

Abstract: An objective process for estimation of star cluster parameters from Hertzsprung–Russell (HR) diagrams is introduced, with direct inclusion of multiple ...

Despite its utility in identifying patterns in celestial objects, the Hertzsprung-Russell diagram is not supported in dim or small stars; it struggles to provide insights into certain celestial ...

Discover the Hertzsprung-Russell diagram, a key tool graphing the brightness of stars against color in astronomy. That's really funny, and I wish I had thought of it. The vertical axis is fame, as ...

Eye in the sky: the TESS spacecraft has been used to identify a new class of supergiant stars. (Courtesy: NASA) A new class of stars called “fast yellow pulsating supergiants” has been identified by ...
