Abstract

We present the first scattered-light image of the debris disk around HD 129590, a ~1.3 M_⊙ G1V member of the Scorpius–Centaurus association with an age of ~10–16 Myr. The debris disk is imaged with the high contrast imaging instrument SPHERE at the Very Large Telescope, and is revealed by both the IRDIS and IFS subsytems, operating in the H and YJ bands respectively. The disk has a high infrared luminosity of L_(IR)/(L)_(star) ~ 5 × 10^(−3), and has been resolved in other studies using ALMA. We detect a nearly edge-on ring, with evidence of an inner clearing. We fit the debris disk using a model characterized by a single bright ring, with radius ~60–70 au, in broad agreement with previous analyses of the target SED. The disk is vertically thin, and has an inclination angle of ~75°. Along with other previously imaged edge-on disks in the Sco–Cen association such as HD 110058, HD 115600, and HD 111520, this disk image will allow of the structure and morphology of very young debris disks, shortly after the epoch of planet formation has ceased.
