The SPHERE infrared survey for exoplanets (SHINE) V. Full sample characterization
V. Squicciarini, S. Desidera, G. Chauvin +109
Unbiased surveys of large stellar samples are the prime means through which the prevalence of exoplanets can be derived, and crucial constraints to planet formation models can be s…
Efficiently combining Alpha CenA multi-epoch high-contrast imaging data. Application of K-Stacker to the 80 hrs NEAR campaign
Hervé Le Coroller, Mathias Nowak, Kevin Wagner +4
Keplerian-Stacker is an algorithm able to combine multiple observations acquired at different epochs taking into account the orbital motion of a potential planet present in the ima…
Constraining masses and separations of unseen companions to five accelerating nearby stars
D. Mesa, M. Bonavita, S. Benatti +39
Aims. This work aims at constraining the masses and separations of potential substellar companions to five accelerating stars (HIP 1481, HIP 88399, HIP 96334, HIP 30314 and HIP 116…
In-depth direct imaging and spectroscopic characterization of the young Solar System analog HD 95086
C. Desgrange, G. Chauvin, V. Christiaens +48
Context. HD 95086 is a young nearby Solar System analog hosting a giant exoplanet orbiting at 57 au from the star between an inner and outer debris belt. The existence of additiona…
The SPHERE infrared survey for exoplanets (SHINE) -- II. Observations, Data reduction and analysis Detection performances and early-results
M. Langlois, R. Gratton, A. -M. Lagrange +118
Over the past decades, direct imaging has confirmed the existence of substellar companions (exoplanets or brown dwarfs) on wide orbits (>10 au) from their host stars. To understand…
Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
Searching for the near infrared counterpart of Proxima c using multi-epoch high contrast SPHERE data at VLT
R. Gratton, A. Zurlo, H. Le Coroller +43
Proxima Centauri is known to host an earth-like planet in its habitable zone; very recently a second candidate planet was proposed based on radial velocities. At quadrature, the ex…
SPHERE dynamical and spectroscopic characterization of HD142527B
R. Claudi, A. -L. Maire, D. Mesa +50
We detect the accreting low-mass companion HD142527B at a separation of 73 mas (11.4 au) from the star. No other companions with mass greater than 10 MJ are visible in the field of…
Observations of fast-moving features in the debris disk of AU Mic on a three-year timescale: Confirmation and new discoveries
A. Boccaletti, E. Sezestre, A. -M. Lagrange +60
The nearby and young M star AU Mic is surrounded by a debris disk in which we previously identified a series of large-scale arch-like structures that have never been seen before in…
Spectral and atmospheric characterization of 51 Eridani b using VLT/SPHERE
M. Samland, P. Mollière, M. Bonnefoy +37
51 Eridani b is an exoplanet around a young (20 Myr) nearby (29.4 pc) F0-type star, recently discovered by direct imaging. Being only 0.5" away from its host star it is well suited…
Resolving the planet-hosting inner regions of the LkCa 15 disk
C. Thalmann, M. Janson, A. Garufi +28
LkCa 15 hosts a pre-transitional disk as well as at least one accreting protoplanet orbiting in its gap. Previous disk observations have focused mainly on the outer disk, which is…
K-Stacker, a new way of detecting and characterizing exoplanets with high contrast imaging instruments
H. Le Coroller, M. Nowak, L. Arnold +4
This year, a second generation of coronagraphs dedicated to high-contrast direct imaging of exoplanets is starting operations. Among them, SPHERE, installed at the focus of the UT3…
The Carlina-type diluted telescope: Stellar fringes on Deneb
H. Le Coroller, J. Dejonghe, F. Hespeels +11
Context. The performance of interferometers has largely been increased over the last ten years. But the number of observable objects is still limited due to the low sensitivity and…
Planet Formation Imager (PFI): Introduction and Technical Considerations
John D. Monnier, Stefan Kraus, David Buscher +13
Complex non-linear and dynamic processes lie at the heart of the planet formation process. Through numerical simulation and basic observational constraints, the basics of planet fo…
Measuring differential rotation of the K-giant \,And
Zs. Kővári, H. Korhonen, L. Kriskovics +5
We investigate the temporal spot evolution of the K-giant component in the RS CVn-type binary system \,Andromedae to establish its surface differential rotation. Doppler imaging…
Tests with a Carlina-type diluted telescope; Primary coherencing
H. Le Coroller, J. Dejonghe, X. Regal +10
Studies are under way to propose a new generation of post-VLTI interferometers. The Carlina concept studied at the Haute- Provence Observatory is one of the proposed solutions. It…
Simulations of coronagraphy with a dynamic hologram for the direct detection of exo-planets
Davide Ricci, Hervé Le Coroller, Antoine Labeyrie +1
In a previous paper, we discussed an original solution to improve the performances of coronagraphs by adding, in the optical scheme, an adaptive hologram removing most of the resid…
