ALMA observations of alpha Centauri: First detection of main-sequence stars at 3mm wavelength
R. Liseau, W. Vlemmings, A. Bayo +19
The precise mechanisms that provide the non-radiative energy for heating the chromosphere and the corona of the Sun and those of other stars constitute an active field of research.…
Unveiling new stellar companions from the PIONIER exozodi survey
Lindsay Marion, Olivier Absil, Steve Ertel +2
The main goal of the EXOZODI survey is to detect and characterize circumstellar dust and to propose the first statistical study of exozodiacal disks in the near-infrared using tele…
A near-infrared interferometric survey of debris-disc stars. IV. An unbiased sample of 92 southern stars observed in H-band with VLTI/PIONIER
Steve Ertel, Olivier Absil, Denis Defrere +8
Context. Detecting and characterizing circumstellar dust is a way to study the architecture and evolution of planetary systems. Cold dust in debris disks only traces the outer regi…
Searching for faint companions with VLTI/PIONIER. II. 92 main sequence stars from the Exozodi survey
Lindsay Marion, Olivier Absil, Steve Ertel +6
The Exozodi survey aims to determine the occurrence rate of bright exozodiacal discs around nearby main sequence stars using infrared interferometry. Although the Exozodi survey ta…
Interpreting the extended emission around three nearby debris disc host stars
Jonathan P. Marshall, F. Kirchschlager, S. Ertel +7
Cool debris discs are a relic of the planetesimal formation process around their host star, analogous to the solar system's Edgeworth-Kuiper belt. As such, they can be used as a pr…
HD139614: the interferometric case for a group-Ib pre-transitional young disk
Lucas Labadie, Alexis Matter, Alexander Kreplin +7
The Herbig Ae star HD 139614 is a group-Ib object, which featureless SED indicates disk flaring and a possible pre-transitional evolutionary stage. We present mid- and near-IR inte…
VLTI status update: a decade of operations and beyond
Antoine Merand, Roberto Abuter, Emmanuel Aller-Carpentier +44
We present the latest update of the European Southern Observatory's Very Large Telescope interferometer (VLTI). The operations of VLTI have greatly improved in the past years: redu…
Collisional modelling of the debris disc around HIP 17439
Ch. Schüppler, T. Löhne, A. V. Krivov +3
We present an analysis of the debris disc around the nearby K2 V star HIP 17439. In the context of the Herschel DUNES key programme the disc was observed and spatially resolved in…
How dusty is alpha Centauri? Excess or non-excess over the infrared photospheres of main-sequence stars
J. Wiegert, R. Liseau, P. Thébault +19
[Abridged] Debris discs around main-sequence stars indicate the presence of larger rocky bodies. The components of the nearby binary aCentauri have higher than solar metallicities,…
