Analytical model-based analysis of long-exposure images fromground-based telescopes

Lucie Leboulleux, Raphaël Galicher, Eric Gendron +2

The search for Earth-like exoplanets requires high-contrast and high-angular resolution instruments, which designs can be very complex: they need an adaptive optics system to compe…

MICADO PSF-Reconstruction work package description

Matteo Simioni, Carmelo Arcidiacono, Andrea Grazian +25

The point spread function reconstruction (PSF-R) capability is a deliverable of the MICADO@ESO-ELT project. The PSF-R team works on the implementation of the instrument software de…

The GRAVITY Young Stellar Object survey IV. The CO overtone emission in 51 Oph at sub-au scales

GRAVITY Collaboration, M. Koutoulaki, R. Garcia Lopez +69

51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 micron, most likely originating in the innermost regions of a circumstellar disc.…

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…

Direct confirmation of the radial-velocity planet Pic c

M. Nowak, S. Lacour, A. -M. Lagrange +90

Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…

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…
