Interferometric Fringe Visibility Null as a Function of Spatial Frequency: A Probe of Stellar Atmospheres
Abstract
We introduce an observational tool based on visibility nulls in optical spectro-interferometry fringe data to probe the structure of stellar atmospheres. In a preliminary demonstration, we use both Navy Precision Optical Interferometer (NPOI) data and stellar atmosphere models to show that this tool can be used, for example, to investigate limb darkening.
