We recently reported on the detection of a possible planetary-mass companion to Beta Pictoris at a projected separation of 8 AU from the star, using data taken in November 2003 with NaCo, the adaptive-optics system installed on the Very Large Telescope UT4. Eventhough no second epoch detection was available, there are strong arguments to favor a gravitationally bound companion rather than a background object. If confirmed and located at a physical separation of 8 AU, this young, hot (~1500 K…

Independent confirmation of β Pictoris b imaging with NICI
Context. Ever since it was identified with VLT/NaCo as a bona-fide exoplanet with a mass of about 9 times that of Jupiter at an orbital separation of 8–9 AU, β Pictoris b has been one of the most
A Giant Planet Imaged in the Disk of the Young Star β Pictoris
It is shown that the ~10-million-year-oldβ Pictoris system hosts a massive giant planet, β Pictoris b, located 8 to 15 astronomical units from the star, which confirms that gas giant planets form rapidly within disks and validates the use of disk structures as fingerprints of embedded planets.
Deep near-infrared interferometric search for low-mass companions around β Pictoris
Aims. We search for low-mass companions in the innermost region (<300 mas, i.e., 6 AU) of the β Pic planetary system. Methods. We obtained interferometric closure phase measurements in the K-band
K-Stacker: an algorithm to hack the orbital parameters of planets hidden in high-contrast imaging
Context. Recent high-contrast imaging surveys, using the Spectro-Polarimetic High contrast imager for Exoplanets REsearch (SPHERE) or the Gemini Planet Imager in search of planets in young, nearby
Deep infrared imaging of close companions to austral A- and F-type stars
The search for substellar companions around stars with different masses along the main sequence is critical to understanding the different processes leading to the formation of low-mass stars, brown
We present and analyze a new M′ detection of the young exoplanet β Pictoris b from 2008 VLT/NaCo data at a separation of ≈4 AU and a high signal-to-noise rereduction of L′ data taken in 2009
Imaging Extrasolar Giant Planets
High-contrast adaptive optics (AO) imaging is a powerful technique to probe the architectures of planetary systems from the outside-in and survey the atmospheres of self-luminous giant planets.
Shaping HR8799’s outer dust belt with an unseen planet
HR8799 is a benchmark system for direct imaging studies. It hosts two debris belts, which lie internally and externally to four giant planets. This paper considers how the four known planets and a
bRing: An observatory dedicated to monitoring the $\beta$ Pictoris b Hill sphere transit
Aims. We describe the design and first light observations from the $\beta$ Pictoris b Ring ("bRing") project. The primary goal is to detect photometric variability from the young star $\beta$
Detectability of giant planets in protoplanetary disks by CO emission lines
In this paper we intend to provide an indirect method to detect Jovian planets by studying near infrared emission spectra originating in the protoplanetary disks around T Tauri stars. Our idea is to


A novel L-band imaging search for giant planets in the Tucana and β Pictoris moving groups
Context. Direct imaging using various techniques for suppressing the stellar halo nowadays can achieve the contrast levels required to detect and characterize the light of substellar companions at
Coronagraphic near-IR photometry of AB Doradus C
Context. Observations of low-mass companions for which the dynamical masses are well constrained help to improve the calibration of evolutionary models. Such observations thereby provide more
Is Beta Pic b the transiting planet of November 1981
In 1981, Beta Pictoris showed strong and rapid photometric variations that were attributed to the transit of a giant comet or a planet orbiting at several AUs (Lecavelier des Etangs et al. 1994,
A companion to AB Pic at the planet/brown dwarf boundary
