no code implementations15 Dec 2020 A. -L. Maire, E. Huby, O. Absil, G. Zins, M. Kasper, C. Delacroix, S. Leveratto, M. Karlsson, G. Ruane, H. -U. Käufl, G. Orban de Xivry, P. Pathak, L. Pettazzi, P. Duhoux, J. Kolb, E. Pantin, A. J. Eldorado Riggs, R. Siebenmorgen, D. Mawet

Here, we present the design of the mid-IR vortex coronagraph for the new Earths in the $\alpha$ Cen Region (NEAR) experiment with the VLT/VISIR instrument and assess the performance of the QACITS estimator for the centering control of the star image onto the vortex coronagraph.

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 SgrA* than S2, the orbit of which recently provided the measurement of the gravitational redshift and the Schwarzschild precession.

The highly elliptical, 16-year-period orbit of the star S2 around the massive black hole candidate Sgr A* is a sensitive probe of the gravitational field in the Galactic centre.
