Summary

Color-magnitude diagram of M3.

DescriptionM3 color magnitude diagram.jpg	This is a color-magnitude diagram for the Messier 3 globular cluster (after A.R. Sandage 1953). The colored points on the chart represent the plotted positions of stars in the cluster. The horizontal scale is based on the B—V color index of the measured stars. From the main sequence stars at magnitude 19 and fainter, the plot forms a knee that bends toward the upper right. Based on the position of the knee, the distance modulus for this cluster is determined to be 15.7. The stars along the upper right branch have left the main sequence and entered the red giant stage. From the red giants branch, a horizontal branch then runs to the left. Note the gap in this branch at visual magnitude 15–16 and spectral type A, where there is a population of variable stars.

This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.

It is recommended to name the SVG file “M3 color magnitude diagram.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

This graph image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.
