Title: Revealing the physics of Young Stellar Objects with GRAVITY/VLTI
Abstract: It is well-established that low- to intermediate-mass stars form via accreting disks. Over the past decade, a remarkable variety of morphologies have been uncovered through interferometric observations at radio wavelengths (e.g., with the VLA and ALMA) and, more recently, with infrared coronagraphs (e.g., with SPHERE/VLT and GPI).
Infrared interferometers have also been employed to study these objects, allowing us (i) to resolve the inner rims of the accreting disks, (ii) the detection of accretion signatures, and (iii) the tracing of formation regions of lines such as BrG and CO.
This presentation will review some of these discoveries obtained with the GRAVITY instrument at the Very Large Telescope Interferometer.
Specifically, I will showcase state-of-the-art milliarcsecond resolution images (of both continuum and line) of several sources (HD 163296, HD 45677, and R CrA), where binarity and variability of the inner rim are observed at spatial scales less than 5 au from the forming star.
Furthermore, I will discuss open questions that we aim to address in the coming years with the anticipated advancements in infrared interferometry.
In particular, I will highlight the new capabilities of GRAVITY(+) and my role as Co-PI in the design and construction of the new high-spectral resolution mode of this instrument, which is crucial for studying young stellar objects.
