Chandra Educational Materials The Hertzsprung Russell Diagram The hertzsprung russell (h r) diagram is an analog to the periodic table of the elements. it was discovered that when the absolute magnitude (m v) – intrinsic brightness – of stars is plotted against their surface temperature (stellar classification) the stars are not randomly distributed on the graph but are mostly restricted to a few well defined regions. Mira variables are periodic pulsating red giants with periods of 80 to 1000 days. it is a stage that most mid sized main sequence stars transition through as they evolve to the red giant branch. miras have amplitude variations of more than 2.5 magnitudes. mira (omicron ceti) is the prototype of mira variable stars.
Chandra Educational Materials Pulsating Variable Stars And The The hertzsprung russell diagram, or h r diagram, is the periodic table of the stars – an analog of the periodic table of the elements. it was discovered that when the luminosity (absolute magnitude or brightness) of stars is plotted against their temperature (stellar classification) the stars are not randomly distributed on the graph but are mostly restricted to a few well defined regions. The traditional hertzsprung russell (h r) diagram activity is a plot of the nearest and brightest stars. this activity is an extension of the traditional plotting activity, and begins with an h r diagram with enough bright and nearby stars plotted to define the shape and location of the main sequence, and the location of the giant and white. (aavso) and the chandra x ray mission have . collaborated with variable star observations and educational materials in their mutual quest to understand stellar processes and evolution. the h r diagram student activity is an example of how evidence is used to construct a model to explain complex concepts – in this case the evolution of stars. The hertzsprung russell diagram, or h r diagram, is the periodic table of the stars. when we talk about stars, we often refer to them based upon their position in the h r diagram. for example, we call stars that are still burning hydrogen in their cores main sequence stars, and will often refer to stars younger and older than main sequence.
