Peering through the disc of HD 98800 BaBb. Precise timing predictions for the HD 98800 AaAb occultation
S. Zúñiga-Fernández, A. Bayo, J. Olofsson +2
The authors refine the orbital parameters of the young quadruple system HD 98800 to provide precise timing windows for when the polar circumbinary disc around the BaBb pair will oc…

Astrometric view of companions in the inner dust cavities of protoplanetary disks
Miguel Vioque, Richard A. Booth, Enrico Ragusa +16
Protoplanetary disks with inner dust cavities (often referred to as "transition disks") are potential signposts of planet formation. We use Gaia astrometry to search for planetary…

Probing dust and grain growth in the optically thick circumbinary ring of V892 Tau
Antoine Alaguero, François Ménard, Nicolás Cuello +5
A considerable proportion of young stars belong to multiple star systems. Constraining the planet formation processes in multiple stellar systems is then key to understand the glob…
