Revealing asymmetrical dust distribution in the inner regions of HD141569
(European Southern Observatory (ESO), 2021)
Context. The combination of high-contrast imaging with spectroscopy and polarimetry offers a pathway to studying the grain distribution and properties of debris disks in exquisite detail. Here, we focus on the case of a ...
Discovery of concentric broken rings at sub-arcsec separations in the HD141569A gas-rich, debris disk with VLT/SPHERE
(EDP Sciences, 2016)
Context. Transition disks correspond to a short stage between the young protoplanetary phase and older debris phase. Along this evolutionary sequence, the gas component disappears leaving room for a dust-dominated environment ...
