Why Is Kathy Vivas Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Anna Katherina Vivas is a Venezuelan astrophysicist recognized for her investigations of and finding up to 100 new and very distant RR Lyrae stars. They are between 13,000 and 220,000 light years from the Sun, and are considered some of the oldest in the Milky Way. Her research has enabled some of the first studies of the structure and properties of the whole halo of the Milky Way and not only its innermost parts. The observation was made possible by combining a telescope with a large format camera, allowing astronomers to cover large portions of the sky in a short amount of time.
