2MASS J15491331-3539118: a new low-mass wide companion of the GQ Lup system
Juan M. Alcalá,F. Z. Majidi,Silvano Desidera,Antonio Frasca,Carlo F. Manara,Elisabetta Rigliaco,Raffaele Gratton,Mickael Bonnefoy,Elvira Covino,Gael Chauvin,Riccardo Claudi,Valentina D'Orazi,Maud Langlois,C. Lazzoni,Dino Mesa,Joshua E. Schlieder,Arthur Vigan +16 more
TL;DR: In this article, the authors reported the discovery of a wide (projected separation $16.61$^\circ$) companion of the GQ Lup A-B system, most likely gravitationally bound to it.

TL;DR: The SPHERE instrument as discussed by the authors was designed to reach the highest contrast between the host star and the planet, typically inside the seeing halo, in a limited field of view and at short distances from the central star.

TL;DR: In this article, the authors further developed and characterized a method for the direct detection of exoplanets from the ground using spectral and angular dierential imaging, called ANDROMEDA, which combines images appropriately into pseudo-data, then uses all of them in a Maximum-Likelihood framework to estimate the position and potential planets orbiting the observed star.

TL;DR: In this article, high-angular-resolution imaging observations of Hygiea with the VLT/SPHERE instrument reveal a basin-free nearly spherical shape with a volume-equivalent radius of 217 ± 7 km, implying a density of 1,944µ±µ250µm−3 to 1σ.
