GRAVITY+ adaptive optics (GPAO) tests in Europe
Florentin Millour, Guillaume Bourdarot, Jean-Baptiste Le Bouquin +54
We present in this proceeding the results of the test phase of the GRAVITY+ adaptive optics. This extreme AO will enable both high-dynamic range observations of faint companions (i…
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…
First Resolution of Microlensed Images of a Binary-Lens Event
Zexuan Wu, Subo Dong, A. Mérand +72
We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves sh…
Impact of local turbulence on high-order adaptive optics
Hugo Nowacki, Jean-Baptiste Le Bouquin, Carole Gouvret +9
We present an experiment set to address a standard specification aiming at avoiding local turbulence inside the Coudé train of telescopes. Namely, every optical surface should be…
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…
