The Annual Adopt A Variable Star Program

The Annual Adopt a Variable Star Program (AAVSP) is a fundraising program designed to encourage small donations to the AAVSO from a large number of donors each year. The concept is very simple and has been used by other non-profits to raise money for children, animals, and other good causes. In our program you can “adopt” any variable star listed in VSX for one year, for a donation to the AAVSO of $20.00 US (tax-deductible in the US).


When you adopt a star for a year you will receive a star chart of that variable star and at the end of your year you will receive a light curve of your star for that year. Whenever a light curve of your star is created on the Light Curve Generator during your year, your name as an “adopter”, or the name you designate, will appear in a list below the observer listing.

There is no limit to the number of variable stars a person can adopt (at $20.00 per star). There is also no limit to the number of people who can adopt a specific variable star.

We have created a simple web form that will handle the adoptions and donations. 

An associated web page will list all the adopted stars and the donors who have adopted them. The stars will be listed alphabetically by constellation. Stars with no GCVS designation will be listed at the end of the list in alphanumerical order. 

To be perfectly clear, you are not buying a star, you are not becoming the owner of anything pertaining to that star (except bragging rights), we are not naming it after you or your cat or your dog - you are simply donating to the AAVSO in the name(s) of your favorite variable star(s).

Adopt a variable star as a gift to yourself! Adopt a variable star in celebration of a birthday, anniversary, wedding, graduation, promotion, retirement or other milestone! Just think, for those of you who perpetually procrastinate buying Holiday gifts for your friends and loved ones, AAVSP adopted stars will make excellent last-minute stocking stuffers, New Year’s gifts, etc.

We hope you will enjoy this fun new way of supporting the AAVSO mission and will come up with your own ideas how this can be used.
