The LEECH Exoplanet Imaging Survey. Further constraints on the planet architecture of the HR 8799 system
A. -L. Maire, A. J. Skemer, P. M. Hinz +36
Context. Astrometric monitoring of directly-imaged exoplanets allows the study of their orbital parameters and system architectures. Because most directly-imaged planets have long…
Orbital Monitoring of the AstraLux Large M-dwarf Multiplicity Sample
Markus Janson, Carolina Bergfors, Wolfgang Brandner +6
Orbital monitoring of M-type binaries is essential for constraining their fundamental properties. This is particularly useful in young systems, where the extended pre-main sequence…
An Enigmatic Pointlike Feature within the HD 169142 Transitional Disk
Beth A. Biller, Jared Males, Timothy Rodigas +13
We report the detection of a faint pointlike feature possibly related to ongoing planet-formation in the disk of the transition disk star HD 169142. The pointlike feature has a …
The coolest 'stars' are free-floating planets
V. Joergens, M. Bonnefoy, Y. Liu +2
We show that the coolest known object that is probably formed in a star-like mode is a free-floating planet. We discovered recently that the free-floating planetary mass object OTS…
Physical and orbital properties of Beta Pictoris b
M. Bonnefoy, G. -D. Marleau, R. Galicher +13
The intermediate-mass star Beta Pictoris is known to be surrounded by a structured edge-on debris disk within which a gas giant planet was discovered orbiting at 8-10 AU. The physi…
High contrast imaging at the LBT: the LEECH exoplanet imaging survey
Andrew J. Skemer, Philip Hinz, Simone Esposito +34
In Spring 2013, the LEECH (LBTI Exozodi Exoplanet Common Hunt) survey began its 130-night campaign from the Large Binocular Telescope (LBT) atop Mt Graham, Arizona. This surv…
The VLT/NaCo large program to probe the occurrence of exoplanets and brown dwarfs at wide orbits: II- Survey description, results and performances
G. Chauvin, A. Vigan, M. Bonnefoy +29
In anticipation of the VLT/SPHERE planet imager guaranteed time programs, we have conducted a preparatory survey of 86 stars between 2009 and 2013 in order to identify new faint co…
The VLT/NaCo Large program to probe the occurrence of exoplanets and brown dwarfs in wide orbits: I- Sample definition and characterization
S. Desidera, E. Covino, S. Messina +28
Young, nearby stars are ideal targets to search for planets using the direct imaging technique. The determination of stellar parameters is crucial for the interpretation of imaging…
Search for cool giant exoplanets around young and nearby stars - VLT/NaCo near-infrared phase-coronagraphic and differential imaging
A. -L. Maire, A. Boccaletti, J. Rameau +8
[Abridged] Context. Spectral differential imaging (SDI) is part of the observing strategy of current and future high-contrast imaging instruments. It aims to reduce the stellar spe…
Near-Infrared Detection and Characterization of the Exoplanet HD 95086 b with the Gemini Planet Imager
Raphael Galicher, Julien Rameau, Mickael Bonnefoy +6
HD 95086 is an intermediate-mass debris-disk-bearing star. VLT/NaCo observations revealed it hosts a companion (HD 95086 b) at AU. Fol…
Search for cool extrasolar giant planets combining coronagraphy, spectral and angular differential imaging
A. -L. Maire, A. Boccaletti, J. Rameau +8
Spectral differential imaging (SDI) is part of the observing strategy of current and on-going high-contrast imaging instruments on ground-based telescopes. Although it improves the…
The architecture of the LkCa 15 transitional disk revealed by high-contrast imaging
C. Thalmann, G. D. Mulders, K. Hodapp +12
We present four new epochs of Ks-band images of the young pre-transitional disk around LkCa 15, and perform extensive forward modeling to derive the physical parameters of the disk…
New constraints on the formation and settling of dust in the atmospheres of young M and L dwarfs
E. Manjavacas, M. Bonnefoy, J. E. Schlieder +7
We obtained medium-resolution near-infrared spectra of seven young M9.5-L3 dwarfs classified in the optical. We aim to confirm the low surface gravity of the objects in the NIR. We…
A global cloud map of the nearest known brown dwarf
I. J. M. Crossfield, B. Biller, J. E. Schlieder +9
Brown dwarfs -- substellar bodies more massive than planets but not massive enough to initiate the sustained hydrogen fusion that powers self-luminous stars -- are born hot and slo…
A radiative-convective equilibrium model for young giant exoplanets: Application to beta Pictoris b
Jean-Loup Baudino, Bruno Bézard, Anthony Boccaletti +2
We present a radiative-convective equilibrium model for young giant exoplanets. Model predictions are compared with the existing photometric measurements of planet beta Pictoris b…
Characterization of the Benchmark Binary NLTT 33370
J. E. Schlieder, M. Bonnefoy, T. M. Herbst +16
We report the confirmation of the binary nature of the nearby, very low-mass system NLTT 33370 with adaptive optics imaging and present resolved near-infrared photometry and integr…
LEECH: A 100 Night Exoplanet Imaging Survey at the LBT
Andrew Skemer, Daniel Apai, Vanessa Bailey +29
In February 2013, the LEECH (LBTI Exozodi Exoplanet Common Hunt) survey began its 100-night campaign from the Large Binocular Telescope atop Mount Graham in Arizona. LEECH nearly c…
