Bright Star Vega's Secret Revealed by Larry O'Hanlon, Discovery News (April 13, 2006).

Using NPOI, in collaboration with the American Association of Variable Star Observers (AAVSO), Dr. Robert Zavala (U.S. Naval Observatory, Flagstaff Station) has an observing campaign to image the surface of the red giant star Pollux. Learn more at this AAVSO News Web page.

The University of New Mexico's Department of Physics & Astronomy hosts Institute for Astrophysics Lunches and Dr. Robert Zavala (U.S. Naval Observatory, Flagstaff Station) was a series guest in April 2006 and presented, Stellar Astrophysics with the Navy Prototype Opical Interferometer.
