Perspectives of a visible instrument on the VLTI
Florentin Millour, Denis Mourard, Julien Woillez +9
In this paper we present the most promising science cases for a new generation visible instrument on the VLTI and the conceptual idea for the instrumental configuration. We also pr…
Pulsation-triggered dust production by asymptotic giant branch stars
Iain McDonald, Elvire de Beck, Albert A. Zijlstra +1
Eleven nearby (<300 pc), short-period (50-130 days) asymptotic giant branch (AGB) stars were observed in the CO J = (2-1) line. Detections were made towards objects that have evide…
High-Contrast study of the candidate planets and protoplanetary disk around HD~100546
E. Sissa, R. Gratton, A. Garufi +62
The nearby Herbig Be star HD100546 is known to be a laboratory for the study of protoplanets and their relation with the circumstellar disk that is carved by at least 2 gaps. We ob…
The curious case of II Lup: a complex morphology revealed with SAM/NACO and ALMA
Foteini Lykou, Albert A. Zijlstra, Jacques Kluska +5
We present the first-ever images of the circumstellar environment of the carbon-rich AGB star II Lup in the infrared and sub-mm wavelengths, and the discovery of the envelope's non…
The gravitational mass of Proxima Centauri measured with SPHERE from a microlensing event
A. Zurlo, R. Gratton, D. Mesa +19
Proxima Centauri, our closest stellar neighbour, is a low-mass M5 dwarf orbiting in a triple system. An Earth-mass planet with an 11 day period has been discovered around this star…
Astrometric and photometric accuracies in high contrast imaging: The SPHERE speckle calibration tool (SpeCal)
R. Galicher, A. Boccaletti, D. Mesa +21
The consortium of the Spectro-Polarimetric High-contrast Exoplanet REsearch installed at the Very Large Telescope (SPHERE/VLT) has been operating its guaranteed observation time (2…
