45 the hertzsprung-russell diagram plots ________ against the spectral type or temperature.
The Hertzsprung-Russell diagram is named after two astronomers, Danish astronomer Eijer Hertzsprung and American astronomer Henry Russell. This diagram is a result of the work carried out by both these astronomers independently. Hertzsprung had plotted the luminosity of a star against its color and effective temperature. This was done in 1911. In 1913, Russell plotted the luminosity of a star ...

In 1911, a Danish astronomer named Ejnar Hertzsprung plotted the absolute magnitude against color for a collection of stars and noticed that there was a strong correlation between these two variables. Independently, an American astronomer named Henry Russell produced a similar plot. Answer (1 of 5): The Hertzprung-Russell (H-R) diagram is a plot of stars' surface temperature (or a variable that's directly tied to temperature) against stars' energy output (or a variable directly tied to energy output).

The diagram plots the absolute magnitude of a star against its spectrum. Thus, to put any star on the diagram, we only need to know its surface temperature (which relates to its spectral type) and the absolute brightness. Astronomers can determine the spectral type for visible stars if the telescope can gather enough light. The Hertzsprung-Russell Diagram plots _____ against the spectral type or temperature. a) size or density b) luminosity or absolute magnitude distance c) mass d) brightness or apparent magnitude. b) luminosity or absolute magnitude distance. How might the most common occurring stars be described, based on our stellar neighborhood? Henry Norris Russell. 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 ...

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.
