Unlocking the dynamics of Young Stellar Objects: Time-Domain Interferometry with six 4-m class telescopes
A. Soulain, B. Lopez, A. Matter +32
The dynamics of the inner regions of young stellar objects (YSOs) is driven by a variety of physical phenomena, from magnetospheres and accretion to the dust sublimation rim and in…
Revealing the accelerating wind in the inner region of the colliding-wind binary WR 112
John D. Monnier, Yinuo Han, Michael F. Corcoran +17
Colliding winds in massive binaries generate X-ray-bright shocks, synchrotron radio emission, and sometimes even dusty "pinwheel" spirals. We report the first X-ray detections of t…
Dynamic Imprints of Colliding-wind Dust Formation from WR140
Emma P. Lieb, Ryan M. Lau, Jennifer L. Hoffman +24

The GRAVITY young stellar object survey XIV : Investigating the magnetospheric accretion-ejection processes in S CrA N
GRAVITY Collaboration, H. Nowacki, K. Perraut +53
The dust- and gas-rich protoplanetary disks around young stellar systems play a key role in star and planet formation. While considerable progress has recently been made in probing…
The James Webb Interferometer: Space-based interferometric detections of PDS 70 b and c at 4.8 m
Dori Blakely, Doug Johnstone, Gabriele Cugno +22
We observed the planet-hosting system PDS 70 with the James Webb Interferometer, JWST's Aperture Masking Interferometric (AMI) mode within NIRISS. Observing with the F480M filter c…
The GRAVITY young stellar object survey XIII. Tracing the time-variable asymmetric disk structure in the inner AU of the Herbig star HD98922
GRAVITY Collaboration, V. Ganci, L. Labadie +52
Temporal variability in the photometric and spectroscopic properties of protoplanetary disks is common in YSO. However, evidence pointing toward changes in their morphology over sh…
