Revised orbital parameters of the gamma2 Velorum system
Werner Schmutz, Christian A. Hummel, Gloria Koenigsberger +2
Context. gamma2 Velorum is the closest and visually brightest Wolf-Rayet binary system. Its eccentric orbit modulates the X-rays observed from the wind-wind interaction, and its la…
Resolving the smallest scales of massive star formation: A case for next-generation thermal-infrared interferometers
Emma Bordier, Evgenia Koumpia, Lucas Labadie +3
This white paper was submitted to the European Southern Observatory (ESO) as part of the "Expanding horizons: transforming astronomy in the 2040s" call. Understanding how massive s…
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…
Searching for low-mass companions at small separations in transition disks with aperture masking interferometry
Tomas Stolker, Jens Kammerer, Myriam Benisty +9
Transition disks have large central cavities that have been spatially resolved during recent years. Cavities and other substructures in circumstellar disks are often interpreted as…
