TL;DR: 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.

TL;DR: In this paper, a point-like signal is detected at a projected distance of 8 AU from the star, within the northeastern extension of the dust disk, which suggests a formation process by core accretion or disk instabilities rather than binary-like formation processes.

TL;DR: In this article, the authors investigate the photometric error and the consequences on the determination of the physical parameters of the detected planets and apply this empirical accuracy to study the characterization capabilities of a high-contrast differential imager.

TL;DR: In this article, the projected position of a giant, close-by planet orbiting a young star surrounded by a disk was measured with a single high-resolution image, and correcting for systematics or errors that degrade the precision of the disk and planet relative position measurements.

TL;DR: In this article, the authors used optimized angular differential imaging techniques to remove the light of the star, revealing the disk component as a distinct narrow ring at inclination i = 84: 3�1: 0 �.
