TL;DR
This paper presents high-resolution ALMA 1.3 mm observations of the HD 95086 system, revealing the structure of its debris disk, the location of its Kuiper-belt analog, and a background galaxy, providing insights into planetary system formation.
Contribution
First resolved the Kuiper-belt analog in HD 95086, characterizing its broad, inclined disk and sharp boundaries, and identified a background galaxy near the disk edge.
Findings
The debris disk extends from 106 to 320 au with a power-law surface density.
The Kuiper-belt analog is a broad, inclined ring at about 200 au.
A bright source near the disk edge is likely a high-redshift galaxy.
Abstract
Planets and minor bodies such as asteroids, Kuiper-belt objects and comets are integral components of a planetary system. Interactions among them leave clues about the formation process of a planetary system. The signature of such interactions is most prominent through observations of its debris disk at millimeter wavelengths where emission is dominated by the population of large grains that stay close to their parent bodies. Here we present ALMA 1.3 mm observations of HD 95086, a young early-type star that hosts a directly imaged giant planet b and a massive debris disk with both asteroid- and Kuiper-belt analogs. The location of the Kuiper-belt analog is resolved for the first time. The system can be depicted as a broad (0.84), inclined (30\arcdeg3\arcdeg) ring with millimeter emission peaked at 2006 au from the star. The 1.3 mm disk emission is consistent…
