TL;DR: In this article , the authors present new $H$-band observations of the disk around HD 129590, which display an intriguing arc-like structure in total intensity but not in polarimetry, and propose an explanation for the origin of this arc.

TL;DR: In this article , the first resolved image in scattered light of the debris disk HD121617 has been presented, which fits the morphology of the disk, finding a semi-major axis of 78.3 au, an inclination of 43.2 au, and a position angle of the major axis with respect to north, of 239.8$\pm$0.

TL;DR: The HD 18327 debris ring exhibits strong polarisation properties, with a maximum degree of linear polarisation of 23.6%. The scattering properties of the dust are consistent with compact spherical particles made of a highly refractive and relatively absorbing material.

Stellar winds can affect gas dynamics in debris disks and create observable belt winds
TL;DR: In this paper , the transition from a gas disk to a gas wind was explored and whether it can be used to determine the stellar wind properties around main-sequence stars that are otherwise hard to measure.
The halo around HD 32297: µ m-sized cometary dust
TL;DR: The optical properties of the second generation dust that we observe in debris disks remain quite elusive, whether it is the absorption e ffi ciencies at millimeter wavelengths or the (un)polarized phase function at near-infrared wavelengths as mentioned in this paper .
