Using VLTI/GRAVITY+ to determine the identity of a third planet candidate in the PDS 70 system

David Trevascus, Wolfgang Brandner, Olga Balsalobre-Ruza +75

Detections of protoplanets are rare and protoplanetary disk features mischaracterized as planets are common. PDS 70 is one of only two stars known to host multiple confirmed protop…

Two inner dust clumps in PDS 70. A third protoplanet traced by trojan material or a substructured inner disk?

O. Balsalobre-Ruza, V. Christiaens, N. Huélamo +21

The PDS 70 cavity hosts two confirmed directly imaged protoplanets and a third inner planet candidate at 13au, labeled PDS 70 d. Despite its Keplerian motion, its unusually blue sp…

Destructuring the disk of AB Aurigae: Dynamics and accretion

Anthony Boccaletti, Emmanuel Di Folco, Anne Dutrey +23

In this paper, we present near-IR polarized images of the AB Aur disk at three epochs spanning 3.85 years with SPHERE/IRDIS, as well as Halpha images obtained with SPHERE/ZIMPOL at…

Exoplanet atmospheres and demographics in the 2040s

Jens Kammerer, Sydney Vach, Sylvestre Lacour +7

Direct observations of exoplanets probe the demographics and atmospheric composition of young self-luminous companions, yielding insight into their formation and early evolution hi…

Exoplanets in reflected starlight with dual-field interferometry and a fifth Unit Telescope at VLTI

Óscar Carrión-González, Sylvestre Lacour, Mathias Nowak

In this white paper, we propose an upgrade to the Very Large Telescope Interferometer (VLTI) consisting of the addition of a new 8m Unit Telescope (UT5). The primary goal of this u…

Hunting exomoons with a kilometric baseline interferometer

Thomas O. Winterhalder, Antoine Mérand, Sylvestre Lacour +3

Despite numerous search campaigns based on a diverse set of observational techniques, exomoons - prospective satellites of extrasolar planets - remain an elusive and hard-to-pin-do…
