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…
