We present near-infrared K-band interferometric measurements of the Mira star R Leonis obtained in April 2001 and January 2002 with the VLTI, the commissioning instrument VINCI, and the two test siderostats. These epochs correspond to near-maximum stellar variability phases ∼0.08 and ∼1.02 (one cycle later), respectively. The April 2001 data cover a range of spatial frequencies (31-35 cycles/arcsecond) within the first lobe of the visibility function. These measurements indicate a...[Show more]
