Debris disks are tenuous, dust-dominated disks commonly observed around stars over a
wide range of ages. Those around main sequence stars are analogous to the Solar System's …

Circumstellar dust exists around several hundred main sequence stars. For the youngest
stars, that dust could be a remnant of the protoplanetary disk. Mostly it is inferred to be …

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 …

The Gemini Planet Imager is a dedicated facility for directly imaging and spectroscopically
characterizing extrasolar planets. It combines a very high-order adaptive optics system, a …

Here, we show that the~ 10-million-year-old β Pictoris system hosts a massive giant planet,
β Pictoris b, located 8 to 15 astronomical units from the star. This result confirms that gas …

The possibility of creating and manipulating entangled states of systems of many particles is
of significant interest for quantum information processing; such a capability could lead to …

Observations in the past decade have revealed extrasolar planets with a wide range of
orbital semimajor axes and eccentricities. Based on the present understanding of planet …

Context. Since the discovery of its dusty disk in 1984, β Pictoris has become the prototype of
young early-type planetary systems, and there are now various indications that a massive …

Aims. We aim to demonstrate that the presence and mass of an exoplanet can now be
effectively derived from the astrometry of another exoplanet. Methods. We combined …

For the past 400 years, astronomers have sought to observe and interpret the Universe by
building more powerful telescopes. These incredible instruments extend the capabilities of …
