The Hertzsprung–Russell diagram, abbreviated as H–R diagram, HR diagram or HRD, is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their stellar classifications or effective temperatures.The diagram was created independently around 1910 by Ejnar Hertzsprung and Henry Norris Russell, and represented a …

These color-magnitude plots are known as Hertzsprung–Russell diagrams after their co-developers, Ejnar Hertzsprung and Henry Norris Russell. Stars on this band are known as main-sequence stars or dwarf stars. These are the most numerous true stars in the universe, and include the Earth's Sun. After condensation and ignition of a star, it generates thermal energy …
Hertzsprung-Russell diagram – a diagram that plots luminosity against temperature for a group of stars. HII region – an area filled with clouds of ionized hydrogen; the ionization is usually caused by radiation from newborn stars. Hubble law – the principle that a distant galaxy’s recessional velocity is proportional to its distance ...
The hertzsprung-russell diagram plots ________ against the spectral type or temperature..
The Hertzsprung-Russell diagram ( HR diagram) is one of the most important tools in the study of stellar evolution. Developed independently in the early 1900s by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the colour of stars (or spectral type) against their absolute magnitude (the observational HR diagram, also known as a colour-magnitude diagram).
The central temperature of the contracting protostar increases to the point where nuclear reactions begin. ... An important tool in the study of stellar evolution is the Hertzsprung-Russell diagram , which plots the absolute magnitudes of stars against their spectral type (or alternatively, stellar luminosity versus effective temperature). As a star evolves, it moves to …

Temperature; Spectral type; During roughly the same time period, two astronomers created similar plots while investigating the relationships among the properties of stars, and today we refer to these plots as "Hertzsprung-Russell Diagrams," or simply HR diagrams. Even though this is quite a simple two dimensional plot, over the course of the next few lessons, you will see exactly how powerful they are for uncovering a host of information on the nature of stars.
Jan 11, 1997 · The Hertzsprung-Russell (HR) diagram is a plot of stellar luminosity against an indicator of stellar surface temperature (color or spectral type). It is motivated by the blackbody luminosity formula L = (4`pi'`sigma') R 2 T 4. From the HR diagram of nearby stars, we learn of the existence of a main sequence, red giants, and white dwarfs.

One of the most useful and powerful plots in astrophysics is the Hertzsprung-Russell diagram (hereafter called the H-R diagram). It originated in 1911 when the Danish astronomer, Ejnar Hertzsprung, plotted the absolute magnitude of stars against their colour (hence effective temperature). Independently in 1913 the American astronomer Henry Norris Russell used …
