Variable Star Database Instructions

Phase 1

Phase 1 can search for a star in a number of ways:

  • By variable type (to see what types are in the database see the contents page)
  • By the following parameters :magnitude, period, amplitude, RA, and Dec
  • By a specific star name

After making selections, press the submit button. This will return all the stars that meet the entered criteria. If specific stars is selected, the system will go directly to Phase 3, otherwise will go through Phase 2. If the star you requested is not in the database you will be asked if you want to submit a request to have it included.

Phase 2

At this point you will be shown all the stars that fit your request. From these you can select the specific stars of interest by clicking on the check box before each star name. Once this is done you can click on any of the submit buttons to proceed to Phase 3.

Phase 3

At Phase 3 you can get a variety of information about the star. From the table you can select from the following. Clicking on the proper box will open a new window so you can maintain the Phase 3 page to look at additional stars.

  • Information Sheet
  • Finder Chart
  • Magnitude File - a page containing published magnitudes for this star
  • Published Maxima (Future) - a page of published times of maximum light
  • Pub. Period Solution (Future) - a page of published period solutions
  • Calculate Maxima - takes you to a page from which you can calculate when maxima should occur. This is used for planning observing runs to determine if a given star will be available on a given night.
  • Multiple Star Maxima Calculation - click each star you want for a given night and the database will calculate maxima's for all stars clicked in the order the maxima will occur.
