The HOSTS survey - Exozodiacal dust measurements for 30 stars
S. Ertel, D. Defrère, P. Hinz +40
The HOSTS (Hunt for Observable Signatures of Terrestrial Systems) survey searches for dust near the habitable zones (HZs) around nearby, bright main sequence stars. We use nulling…
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…
A dim candidate companion to εCephei
Dimitri Mawet, Bertrand Mennesson, Eugene Serabyn +2
Using a vector vortex coronagraph behind the 1.5-m well-corrected subaperture (WCS) at Palomar, we detected a second object very close to εCephei, a δScuti F0 IV star. The candidat…
Cold dust around nearby stars (DUNES). First results: A resolved exo-Kuiper belt around the solar-like star zeta^2 Ret
C. Eiroa, D. Fedele, J. Maldonado +46
We present the first far-IR observations of the solar-type stars delta Pav, HR 8501, 51 Peg and zeta^2 Ret, taken within the context of the DUNES Herschel Open Time Key Programme (…
Exoplanet Characterization and the Search for Life
J. Kasting, W. Traub, A. Roberge +119
Over 300 extrasolar planets (exoplanets) have been detected orbiting nearby stars. We now hope to conduct a census of all planets around nearby stars and to characterize their atmo…
