TW Hydrae is a T Tauri star approximately 196 light-years away [1] in the constellation of Hydra (the Sea Serpent). TW Hydrae is about 80% of the mass of the Sun, but is only about 5-10 million years old.

2023年5月4日 · Comparison images from the Hubble Space Telescope, taken several years apart, have uncovered two eerie shadows moving counterclockwise across a gas-and-dust disk encircling the young star TW Hydrae. The disks are tilted face-on to Earth and so give astronomers a bird's-eye view of what's happening around the star.

2023年5月4日 · Comparison images from the Hubble Space Telescope, taken several years apart, have uncovered two eerie shadows moving counterclockwise across a gas-and-dust disk encircling the young star TW Hydrae. The disks are tilted face-on to Earth and so give astronomers a bird's-eye view...

2017年1月7日 · This simulation shows a shadow sweeping around a gas-and-dust disk encircling the young star TW Hydrae. The simulated view is based on an analysis of data taken between 1998 and 2016 by NASA's Hubble Space Telescope. This video also shows what the moving shadow might look like...

2016年3月31日 · The star, TW Hydrae, is a popular target of study for astronomers because of its proximity to Earth (approximately 175 light-years away) and its status as a veritable newborn (about 10 million years old). It also has a face-on orientation as seen from Earth. This affords astronomers a rare, undistorted view of the complete disk.

2016年3月30日 · ALMA image of the planet-forming disk around the young, Sun-like star TW Hydrae. The inset image (upper right) zooms in on the gap nearest to the star, which is at the same distance as the Earth is from the Sun, suggesting an infant version of our home planet could be emerging from the dust and gas.

This graphic shows a gap in a protoplanetary disk of dust and gas whirling around the nearby red dwarf star TW Hydrae. The gap's presence is best explained as due to the effects of a growing, unseen planet that is gravitationally sweeping up material …

2025年1月20日 · The TW Hydrae Association (TWA) is a young local association (YLA) about 50 pc from the Sun, offering a unique opportunity to study star and planet formation processes in detail. We characterized TWA's location, kinematics, and age, investigating its origin within the Scorpius-Centaurus (Sco-Cen) OB association.

2016年4月2日 · This structure may mean that an infant version of our home planet, or possibly a more massive “super-Earth,” is beginning to form there. The star, TW Hydrae, is a popular target of study for astronomers because of its proximity to Earth (approximately 175 light-years away) and its status as a veritable newborn (about 10 million years old).

2005年6月9日 · This graphic shows a gap in a protoplanetary disc of dust and gas whirling around the nearby red dwarf star TW Hydrae. The gap's presence is best explained as due to the effects of a growing, unseen planet that is gravitationally sweeping up material and carving out a lane in the disc, like a snow plow.
