Revealing the structure of the outer disks of Be stars
Robert Klement,Robert Klement,Alex C. Carciofi,Thomas Rivinius,Lynn D. Matthews,R. G. Vieira,Richard Ignace,J. E. Bjorkman,Bruno Mota,Daniel M. Faes,A. D. Bratcher,Michel Curé,S. Štefl +12 more
TL;DR: In this article, the spectral energy distribution (SED) of a sample of six Be disks that have been observed in the radio to address the question of whether the observed turndown in the SED can be explained in the framework of the VDD model, including recent theoretical development for truncated Be disks in binary systems.

TL;DR: In this article, the spectral energy distribution (SED) of Be star disks is investigated in the framework of the viscous decretion disk (VDD) model, including recent theoretical development for truncated Be disks in binary systems.
Characterizing the particle size distribution of Saturn’s A ring with Cassini UVIS occultation data
TL;DR: In this paper, a forward model was proposed to reconstruct the spacecraft's observations for each stellar occultation by ring edges, which produced a synthetic diffraction signal for a given truncated power-law particle size distribution, which was compared with the observed signal.
