How does an environments and locations diagram work?
An environments and locations diagram depicts which locations host which applications, identifies what technologies and/or applications are used at which locations, and finally identifies the locations from which business users typically interact with the applications.
What are the main regions of the HR diagram?
There are 3 main regions (or evolutionary stages) of the HR diagram: The main sequence stretching from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) dominates the HR diagram. It is here that stars spend about 90% of their lives burning hydrogen into helium in their cores.
Where are most stars located in the HR diagram?
An HR diagram with the instability strip and its components highlighted. Most of the stars occupy the region in the diagram along the line called the main sequence. During the stage of their lives in which stars are found on the main sequence line, they are fusing hydrogen in their cores.
Where are RR Lyrae variable stars on the H-R diagram?
RR Lyrae variable stars can be found in the left of this gap on a section of the diagram called the instability strip. Cepheid variables also fall on the instability strip, at higher luminosities. The H-R diagram can be used by scientists to roughly measure how far away a star cluster or galaxy is from Earth.
Where is the Sun located on the HR diagram?
The Sun is found on the main sequence with a luminosity of 1 and a temperature of around 5,400 Kelvin. Astronomers generally use the HR diagram to either summarise the evolution of stars, or to investigate the properties of a collection of stars.

Where are white dwarf stars found on the HR diagram?
white dwarf stars (luminosity class D) are the final evolutionary stage of low to intermediate mass stars, and are found in the bottom left of the HR diagram. These stars are very hot but have low luminosities due to their small size. The Sun is found on the main sequence with a luminosity of 1 and a temperature of around 5,400 Kelvin.
What do astronomers use the HR diagram for?
Astronomers generally use the HR diagram to either summarise the evolution of stars, or to investigate the properties of a collection of stars.
