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…
MINDS. A multi-instrument investigation into the molecule-rich JWST-MIRI spectrum of the DF Tau binary system
Sierra L. Grant, Nicolas T. Kurtovic, Ewine F. van Dishoeck +26
Most stars form in multiple systems whose properties can significantly impact circumstellar disk evolution. We investigate the physical and chemical properties of the equal-mass, s…
The GRAVITY young stellar object survey: XI. Imaging the hot gas emission around the Herbig Ae star HD 58647
Y. -I. Bouarour, R. Garcia Lopez, J. Sanchez-Bermudez +45
We aim to investigate the origin of the HI Br emission in young stars by using GRAVITY to image the innermost region of circumstellar disks, where important physical processes s…
Direct discovery of the inner exoplanet in the HD206893 system. Evidence for deuterium burning in a planetary-mass companion
S. Hinkley, S. Lacour, G. -D. Marleau +110
Long term precise radial velocity (RV) monitoring of the nearby star HD206893, as well as anomalies in the system proper motion, have suggested the presence of an additional, inner…
Probing inner and outer disk misalignments in transition disks
A. J. Bohn, M. Benisty, K. Perraut +16
For several transition disks (TDs), dark regions interpreted as shadows have been observed in scattered light imaging and are hypothesized to originate from misalignments between d…
GRAVITY K-band spectroscopy of HD 206893 B: brown dwarf or exoplanet
J. Kammerer, S. Lacour, T. Stolker +94
We aim to reveal the nature of the reddest known substellar companion HD 206893 B by studying its near-infrared colors and spectral morphology and by investigating its orbital moti…
