[5] The system is notable for being young as a member of the 45 Myr old Tucana-Horologium moving group[10] and for the primary star hosting the confirmed exoplanet DS Tucanae Ab, discovered by THYME, using TESS.

[15] Based on radial velocity measurements it was suggested that the secondary itself is a binary, but later studies could not find evidence for this claim.

Of these systems DS Tuc is the brightest and it is a good target for atmospheric characterization with JWST.

[12] DS Tuc Ab will be observed by ESA's CHEOPS mission to characterize the planet.

[19][20] DS Tucanae Ab might therefore be a good target to study in-situ planet-formation of short-period planets.
