TL;DR: In this paper, the authors used simple geometric models to fit the interferometric visibilities and closure phases of the inner disk of HD 163296 to detect potential disk asymmetries and found that the brightness maximum of the asymmetry is located at the NW part of the disk image, nearly at the position angle of the semimajor axis.

TL;DR: In this article, the authors used geometric models to fit the data and revealed a significant brightness asymmetry in the inner disk of the star HD 163296, where the brightness maximum of the asymmetry is located at the NW part of the disk image, nearly at the position angle of the semimajor axis.

TL;DR: In this paper, the authors used photometric observations in various bands (from the visible domain to the infrared) and Spitzer Space Telescope spectroscopy to constrain the geometry and the IR excess of the environment of the bright long-period Cepheid l Car.
