Willson et al. (2016) report a planetary companion detected by Keck sparse aperture masking interferometric observations. Companion detection is at a > 95% (> 4.0σ) confidence level.
Kudo et al. (2018): a 4 AUs radius inner dust ring in DM Tau's protoplanetary disk is most likely produced by orbital motion of the planetary companion.
