A Baby Star Surrounded by a Fluffy Planet-Forming Disk

  An international team of astronomers that are members of the Strategic Exploration of Exoplanets and Disks with Subaru Telescope (SEEDS) Project has used Subaru Telescope’s High Contrast Instrument for the Subaru Next Generation Adaptive Optics (HiCIAO) to observe a disk around the young star RY Tau (Tauri). The team’s analysis of the disk shows [continue reading]

A "Second Jupiter" Discovered

  Astronomers in the Strategic Explorations of Exoplanets and Disks with Subaru (SEEDS) Project have recently discovered and captured an image of the least massive planet ever imaged so far, a so-called “second Jupiter” (Figure 1). This discovery marks an important step toward the direct imaging of much fainter Earth-like planets in the future and [continue reading]

'Super-Jupiter' Around Massive Star Directly Imaged

  Astronomers using infrared data from the Subaru Telescope in Hawaii have discovered a “super-Jupiter” around the bright star Kappa Andromedae, which now holds the record for the most massive star known to host a directly imaged planet or lightweight brown dwarf companion. The “super-Jupiter” Kappa Andromedae b, shown here in an artist’s rendering, circles [continue reading]

A Gap in the Disk of a Sun-Like Star may host Multiple Exoplanets

  A large international team of astronomers led by Jun Hashimoto (National Astronomical Observatory of Japan) and Ruobing Dong (Princeton University) has used the High Contrast Instrument for the Subaru Next Generation Adaptive Optics (HiCIAO) to observe and examine PDS 70 (Note 1), a young star about 10 million years old with a mass similar [continue reading]
