Query: Narrow belt of debris around the Sco-Cen star HD 141011   We initiated a deep-imaging survey of Scorpius-Centaurus A-F stars with
predicted warm inner and cold outer belts of debris reminiscent of the
architecture of emblematic systems such as HR 8799. We present resolved SPHERE
images of a narrow ring of debris around the F5-type star HD 141011 that was
observed as part of our survey in 2015, 2016, and 2019. The ring extends up to
~1.1" (~141 au) from the star in the IRDIS and IFS data obtained in 2016 and
2019. The disk is not detected in the 2015 data which are of poorer quality.
The disks is best reproduced by models of a noneccentric ring centered on the
star with an inclination of $69.1\pm0.9^{\circ}$, a position angle of $-24.6
\pm 1.7^{\circ}$, and a semimajor axis of $127.5\pm3.8$ au. The combination of
radial velocity and imaging data excludes brown-dwarf (M>13.6 MJup) companions
coplanar with the disk from 0.1 to 0.9 au and from 20 au up to 500 au (90%
probability). HD 141011 adds to the growing list of debris disks that are
resolved in Sco-Cen. It is one of the faintest disks that are resolved from the
ground and has a radial extent and fractional width ($\sim$12.5%) reminiscent
of Fomalhaut. Its moderate inclination and large semimajor axis make it a good
target for the James Webb Space Telescope and should allow a deeper search for
putative companions shaping the dust distribution.
