MOLsphere and pulsations of the Galactic Center's red supergiant GCIRS 7 from VLTI/GRAVITY

GRAVITY Collaboration, G. Rodríguez-Coira, T. Paumard +55

GCIRS 7, the brightest star in the Galactic central parsec, formed Myr ago together with dozens of massive stars in a disk orbiting the central black-hole. It has been argu…

Mid-infrared circumstellar emission of the long-period Cepheid l Carinae resolved with VLTI/MATISSE

V. Hocdé, N. Nardetto, A. Matter +149

The nature of circumstellar envelopes (CSE) around Cepheids is still a matter of debate. The physical origin of their infrared (IR) excess could be either a shell of ionized gas, o…

The asymmetric inner disk of the Herbig Ae star HD 163296 in the eyes of VLTI/MATISSE: evidence for a vortex?

J. Varga, M. Hogerheijde, R. van Boekel +133

Context. The inner few au region of planet-forming disks is a complex environment. High angular resolution observations have a key role in understanding the disk structure and the…

Multiple Star Systems in the Orion Nebula

GRAVITY collaboration, Martina Karl, Oliver Pfuhl +133

This work presents an interferometric study of the massive-binary fraction in the Orion Trapezium Cluster with the recently comissioned GRAVITY instrument. We observe a total of 16…

GRAVITY chromatic imaging of Eta Car's core

GRAVITY Collaboration, J. Sanchez-Bermudez, G. Weigelt +132

Eta Car is one of the most intriguing luminous blue variables in the Galaxy. Observations and models at different wavelengths suggest a central binary with a 5.54 yr period residin…

Sub-milliarcsecond Optical Interferometry of the HMXB BP Cru with VLTI/GRAVITY

GRAVITY Collaboration, I. Waisberg, J. Dexter +68

We observe the HMXB BP Cru using interferometry in the near-infrared K band with VLTI/GRAVITY. Continuum visibilities are at most partially resolved, consistent with the predicted…
