The HOSTS survey for exozodiacal dust: Observational results from the complete survey
Steve Ertel, Denis Defrère, Philip M. Hinz +43
The Large Binocular Telescope Interferometer (LBTI) enables nulling interferometric observations across the N band (8 to 13 um) to suppress a star's bright light and probe for fain…
HR 10: A main-sequence binary with circumstellar envelopes around both components. Discovery and analysis
B. Montesinos, C. Eiroa, J. Lillo-Box +16
This paper is framed within a large project devoted to studying the presence of circumstellar material around main sequence stars, and looking for exocometary events. The work conc…
The HOSTS Survey for Exozodiacal Dust: Preliminary results and future prospects
S. Ertel, G. M. Kennedy, D. Defrère +40
[abridged] The presence of large amounts of dust in the habitable zones of nearby stars is a significant obstacle for future exo-Earth imaging missions. We executed an N band nulli…
A near-infrared interferometric survey of debris-disc stars. V. PIONIER search for variability
S. Ertel, D. Defrère, O. Absil +10
Context: Extended circumstellar emission has been detected within a few 100 milli-arcsec around > 10% of nearby main sequence stars using near-infrared interferometry. Follow-up ob…
An Unbiased Near-infrared Interferometric Survey for Hot Exozodiacal Dust
Steve Ertel, Jean-Charles Augereau, Olivier Absil +5
Exozodiacal dust is warm or hot dust found in the inner regions of planetary systems orbiting main sequence stars, in or around their habitable zones. The dust can be the most lumi…
First-light LBT nulling interferometric observations: warm exozodiacal dust resolved within a few AU of eta Corvi
D. Defrère, P. M. Hinz, A. J. Skemer +37
We report on the first nulling interferometric observations with the Large Binocular Telescope Interferometer (LBTI), resolving the N' band (9.81 - 12.41 um) emission around the ne…
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…
