In June 2010, we confirmed the existence of a giant planet in the disk of the young star Beta Pictoris, located between 8 AU and 15 AU from the star. This young planet offers the rare opportunity to monitor a large fraction of the orbit using the imaging technique over a reasonably short timescale. Using the NAOS-CONICA adaptive-optics instrument (NACO) at the Very Large Telescope (VLT), we obtained repeated follow-up images of the Bpic system in the Ks and L' filters at four new epochs in 2010…

### Post-conjunction detection of β Pictoris b with VLT/SPHERE

• Physics, Geology
Astronomy & Astrophysics

Context. With an orbital distance comparable to that of Saturn in the solar system, β Pictoris b is the closest (semi-major axis ≃9 au) exoplanet that has been imaged to orbit a star. Thus it offers

### The orbit of beta Pictoris b as a transiting planet

• Physics, Geology
• 2016
In 1981, Beta Pictoris showed strong and rapid photometric variations possibly due to a transiting giant planet. Later, a planetary mass companion to the star, Beta Pic b, was identified using

• Physics, Geology
Astronomy & Astrophysics
• 2020
Context. β Pictoris is arguably one of the most studied stellar systems outside of our own. Some 30 yr of observations have revealed a highly-structured circumstellar disk, with rings, belts, and a

### Orbital and atmospheric characterization of the planet within the gap of the PDS 70 transition disk

• Physics, Geology
Astronomy & Astrophysics
• 2018
Context. The observation of planets in their formation stage is a crucial but very challenging step in understanding when, how, and where planets form. PDS 70 is a young pre-main sequence star

### The far reaches of the β Pictoris debris disk

• Physics, Geology
• 2021
The nearby young star beta Pictoris hosts a rich and complex planetary system, with at least two giant planets and a nearly edge-on debris disk that contains several dynamical subpopulations of

• Physics, Geology
Astronomy & Astrophysics
• 2019
Context. The 51 Eridani system harbors a complex architecture with its primary star forming a hierarchical system with the binary GJ 3305AB at a projected separation of 2000 au, a giant planet

### Spectral and orbital characterisation of the directly imaged giant planet HIP 65426 b

• Geology, Physics
Astronomy & Astrophysics
• 2019
HIP 65426 b is a recently discovered exoplanet imaged during the course of the SPHERE-SHINE survey. Here we present new L′ and M′ observations of the planet from the NACO instrument at the VLT from

### Fast spin of the young extrasolar planet β Pictoris b

• Physics, Geology
Nature
• 2014
The combined line profile exhibits a rotational broadening of about 25 kilometres per second, meaning that β Pictoris b spins significantly faster than any planet in the Solar System, in line with the extrapolation of the known trend in spin velocity with planet mass.

• Physics, Geology
• 2013
Direct imaging has only begun to inventory the population of gas giant planets on wide orbits around young stars in the solar neighborhood. Following this approach, we carried out a deep imaging
