The Hertzsprung–Russell (HR) diagram classifies stars by plotting their luminosity against the effective temperature of their surface. Excluding white dwarfs and red giants, ...

IT has been suggested several times1 that the flare activity observed in flash and U V Ceti stars is of a nature similar to that of solar flares. In this communication I shall adhere to this point ...

Some are old, some young, some dying, some dead. And they all have their place in what we now call the Hertzsprung-Russel diagram, or H-R diagram for short. It's one of the most useful tools ...
