Journal ArticleDOI
A Giant Planet Imaged in the Disk of the Young Star β Pictoris

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, the authors presented a 0.16% precise and 0.27% accurate determination of R 0, the distance to the Galactic center using the star S2 on its 16-year orbit around the massive black hole Sgr A* that they followed astrometrically and spectroscopically for 27 years.
