Orbital and atmospheric characterization of the planet within the gap of the PDS 70 transition disk
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
Mapping the Shores of the Brown Dwarf Desert
We conduct a multiplicity survey of members of the rho Ophiuchus cloud complex with high resolution imaging to characterize the multiple star population of this nearby star forming region and
Discovery of Seven Companions to Intermediate-mass Stars with Extreme Mass Ratios in the Scorpius–Centaurus Association
We report the detection of seven low-mass companions to intermediate-mass stars (SpT B/A/F; ~ 1.5–4.5 M_⊙) in the Scorpius–Centaurus (Sco–Cen) Association using nonredundant aperture masking
Discovery of a planetary-mass companion within the gap of the transition disk around PDS 70
Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime interest to understand the physical and chemical conditions under which planet formation takes place. Only
The SPHERE view of the planet-forming disk around HD 100546
We thank Paola Pinilla and Sean Brittain for the fruitful scientific discussion, and the referee for a thorough review that helped improve the text. We are grateful to the ESO technical operators at
An M-dwarf star in the transition disk of Herbig HD 142527: physical parameters and orbital elements.
S.L. acknowledges fruitful discussions with S. Casassus about the existence of HD 142527B and the inner disk of HD 142527A. This research made use of Astropy, a community-developed core Python
Atmospheric characterization of Proxima b by coupling the Sphere high-contrast imager to the Espresso spectrograph
Context. The temperate Earth-mass planet Proxima b is the closest exoplanet to Earth and represents what may be our best ever opportunity to search for life outside the Solar System. Aims. We aim at
Discovery of a warm, dusty giant planet around HIP 65426
Aims. The SHINE program is a high-contrast near-infrared survey of 600 young, nearby stars aimed at searching for and characterizing new planetary systems using VLT/SPHERE’s unprecedented
Post-conjunction detection of β Pictoris b with VLT/SPHERE
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
Spectral and atmospheric characterization of 51 Eridani b using VLT/SPHERE
Context. 51 Eridani b is an exoplanet around a young (20 Myr) nearby (29.4 pc) F0-type star, which was recently discovered by direct imaging. It is one of the closest direct imaging planets in
