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…
The GRAVITY young stellar object survey III. The dusty disk of RY Lup
GRAVITY Collaboration, Y. -I. Bouarour, K. Perraut +55
We use PIONIER data from the ESO archive and GRAVITY data that were obtained in June 2017 with the four 8m telescopes. We use a parametric disk model and the 3D radiative transfer…
Retrieving scattering clouds and disequilibrium chemistry in the atmosphere of HR 8799e
P. Mollière, T. Stolker, S. Lacour +25
Clouds are ubiquitous in exoplanet atmospheres and represent a challenge for the model interpretation of their spectra. Complex cloud models are too numerically costly for generati…
Sgr A* near-infrared flares from reconnection events in a magnetically arrested disc
J. Dexter, A. Tchekhovskoy, A. Jiménez-Rosales +14
Large-amplitude Sgr A* near-infrared flares result from energy injection into electrons near the black hole event horizon. Astrometry data show continuous rotation of the emission…
The Flux Distribution of Sgr A*
The GRAVITY Collaboration, R. Abuter, A. Amorim +54
The Galactic Center black hole Sagittarius A* is a variable NIR source that exhibits bright flux excursions called flares. The low-flux density turnover of the flux distribution is…
