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…

Constraining the Nature of the PDS 70 Protoplanets with VLTI/GRAVITY

J. J. Wang, A. Vigan, S. Lacour +101

We present K-band interferometric observations of the PDS 70 protoplanets along with their host star using VLTI/GRAVITY. We obtained K-band spectra and 100 as precision astromet…

The central parsec of NGC 3783: a rotating broad emission line region, asymmetric hot dust structure, and compact coronal line region

GRAVITY Collaboration, A. Amorim, M. Bauböck +47

Using VLTI/GRAVITY and SINFONI data, we investigate the sub-pc gas and dust structure around the nearby type 1 AGN hosted by NGC 3783. The K-band coverage of GRAVITY uniquely allow…

Improved GRAVITY astrometric accuracy from modeling of optical aberrations

GRAVITY Collaboration, R. Abuter, A. Amorim +60

The GRAVITY instrument on the ESO VLTI pioneers the field of high-precision near-infrared interferometry by providing astrometry at the as level. Measurements at such…

Detection of faint stars near SgrA* with GRAVITY

GRAVITY Collaboration, R. Abuter, A. Amorim +58

The spin of the supermassive black hole that resides at the Galactic Centre can in principle be measured by accurate measurements of the orbits of stars that are much closer to Sgr…

Dynamically important magnetic fields near the event horizon of Sgr A*

GRAVITY Collaboration, A. Jiménez-Rosales, J. Dexter +53

We study the time-variable linear polarisation of Sgr A* during a bright NIR flare observed with the GRAVITY instrument on July 28, 2018. Motivated by the time evolution of both th…
