How do I...

Find cataclysmic variables?

Many interesting objects are hidden among the SDSS data. One such object is a cataclysmic variable, a binary star pair in which the two stars are close together, and one star is a white dwarf. This guide comes from a modified form of a query by Dr. Paula Szkody at the University of Washington, an expert in Cataclysmic Variables.

The query uses an SQL Search (link opens in new window) to search for cataclysmic variables (CVs) by their distinctive colors. You can adapt this query to search for other objects by their colors simply by changing the colors that the search requests. You can learn more about SQL from SkyServer's SQL Tutorial.

Next: Search for CVs by color
