Comprehensive analysis of HD 105, a young Solar System analog
J. P. Marshall, J. Milli, É. Choquet +5
HD~105 is a nearby, pre-main sequence G0 star hosting a moderately bright debris disc (). HD~105 and its surroundings might therefore…
Thermal Emission in the Southwest Clump of VY CMa
Michael S. Gordon, Terry J. Jones, Roberta M. Humphreys +6
We present high spatial resolution LBTI/NOMIC images of VY CMa and its massive outflow feature, the Southwest (SW) Clump. Combined with high-resolution imaging from HST…
The LEECH Exoplanet Imaging Survey: Limits on Planet Occurrence Rates Under Conservative Assumptions
Jordan M. Stone, Andrew J. Skemer, Philip M. Hinz +33
We present the results of the largest (m) direct imaging survey for exoplanets to date, the Large Binocular Telescope Interferometer (LBTI) Exozodi Exoplanet Co…
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…
Using warm dust to constrain unseen planets
Amy Bonsor, Mark C. Wyatt, Quentin Kral +3
Cold outer debris belts orbit a significant fraction of stars, many of which are planet-hosts. Radiative forces from the star lead to dust particles leaving the outer belts and spi…
Prospects for the characterisation of exo-zodiacal dust with the VLTI
S. Ertel, O. Absil, D. Defrère +2
Exo-zodiacal dust, exozodi for short, is warm (~300K) or hot (up to ~2000K) dust found in the inner regions of planetary systems around main sequence stars. In analogy to our own z…
Hi-5: a potential high-contrast thermal near-infrared imager for the VLTI
D. Defrère, M. Ireland, O. Absil +25
Hi-5 is a high-contrast (or high dynamic range) infrared imager project for the VLTI. Its main goal is to characterize young extra-solar planetary systems and exozodiacal dust arou…
The TRENDS High-Contrast Imaging Survey. VII. Discovery of a Nearby Sirius-like White Dwarf System (HD 169889)
Justin R. Crepp, Erica J. Gonzales, Brendan P. Bowler +8
Monitoring the long-term radial velocity (RV) and acceleration of nearby stars has proven an effective method for directly detecting binary and substellar companions. Some fraction…
A two-band approach to n phase error corrections with LBTI's PHASECam
E. R. Maier, P. M. Hinz, D. Defrère +2
PHASECam is the Large Binocular Telescope Interferometer's (LBTI) phase sensor, a near-infrared camera which is used to measure tip/tilt and phase variations between the two AO-cor…
Towards controlled Fizeau observations with the Large Binocular Telescope
Eckhart Spalding, Phil Hinz, Steve Ertel +2
The Large Binocular Telescope Interferometer (LBTI) can perform Fizeau interferometry in the focal plane, which accesses spatial information out to the LBT's full 22.7-m edge-to-ed…
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…
The co-existence of hot and cold gas in debris discs
I. Rebollido, C. Eiroa, B. Montesinos +19
Debris discs have often been described as gas-poor discs as the gas-to-dust ratio is expected to be considerably lower than in primordial,protoplanetary discs. However, recent obse…
Space-based infrared interferometry to study exoplanetary atmospheres
D. Defrère, A. Léger, O. Absil +30
The quest for other habitable worlds and the search for life among them are major goals of modern astronomy. One way to make progress towards these goals is to obtain high-quality…
The path towards high-contrast imaging with the VLTI: the Hi-5 project
D. Defrère, O. Absil, J. -P. Berger +26
The development of high-contrast capabilities has long been recognized as one of the top priorities for the VLTI. As of today, the VLTI routinely achieves contrasts of a few 10$^{-…
