Before articles are published in an American Astronomical Society (AAS) journal, the author must grant and assign the entire copyright in it to the AAS. In return, the AAS grants authors the non-exclusive right of republication, subject only to giving appropriate credit to the journal in which your article is published. This non-exclusive right of republication includes your right to allow reproduction of parts of your article wherever you wish, and permits you to post the published (PDF) version of your article on your personal web site. To protect the copyright in your article, the original copyright notice as it appears in the journal should be included in the credit.
