TL;DR
This study systematically compares the reflectance properties of debris disks around various stars using Hubble Space Telescope data, revealing trends in color and dust properties that inform understanding of dust composition and size.
Contribution
It provides a uniform analysis of debris disk reflectance across multiple systems, highlighting color trends and clustering related to dust properties and stellar luminosity.
Findings
Debris birth rings are typically blue at 90° scattering angle.
Color tends to be more neutral with increasing stellar luminosity.
Clustering in color-albedo suggests different dust populations.
Abstract
Multi-wavelength scattered light imaging of debris disks may inform dust properties including typical size and mineral composition. Existing studies have investigated a small set of individual systems across a variety of imaging instruments and filters, calling for uniform comparison studies to systematically investigate dust properties. We obtain the surface brightness of dust particles in debris disks by post-processing coronagraphic imaging observations, and compare the multi-wavelength reflectance of dust. For a sample of resolved debris disks, we perform a systematic analysis on the reflectance properties of their birth rings. We reduced the visible and near-infrared images of 23 debris disk systems hosted by A through M stars using two coronagraphs onboard the Hubble Space Telescope: the STIS instrument observations centering at 0.58 m, and the NICMOS instrument at 1.12…
