Upgrading the high contrast imaging facility SPHERE: science drivers and instrument choices
A. Boccaletti, G. Chauvin, F. Wildi +71
SPHERE+ is a proposed upgrade of the SPHERE instrument at the VLT, which is intended to boost the current performances of detection and characterization for exoplanets and disks. S…
Optical/near-infrared observations of the Fried Egg Nebula: Multiple shell ejections on a 100 yr timescale from a massive yellow hypergiant
E. Koumpia, R. D. Oudmaijer, V. Graham +15
Context. The fate of a massive star during the latest stages of its evolution is highly dependent on its mass-loss rate/geometry and therefore knowing the geometry of the circumste…
Post conjunction detection of Pictoris b with VLT/SPHERE
A. -M. Lagrange, A. Boccaletti, M. Langlois +102
With an orbital distance comparable to that of Saturn in the solar system, \bpic b is the closest (semi-major axis \,9\,au) exoplanet that has been imaged to orbit a star.…
SPHERE / ZIMPOL observations of the symbiotic system R Aqr. I. Imaging of the stellar binary and the innermost jet clouds
H. M. Schmid, A. Bazzon, J. Milli +40
R Aqr is a symbiotic binary system consisting of a mira variable, a hot companion with a spectacular jet outflow, and an extended emission line nebula. We have used R Aqr as test t…
Witnessing the Emergence of a Carbon Star
L. Guzman-Ramirez, E. Lagadec, R. Wesson +9
During the late stages of their evolution, Sun-like stars bring the products of nuclear burning to the surface. Most of the carbon in the Universe is believed to originate from sta…
