... TW Hydrae , a popular astronomy target located 176 light - years away from Earth in the constellation Hydra the Sea Serpent . Hubble Telescope's keen vision detected a mysterious gap in a vast protoplanetary disk of gas and dust ...
... TW Hydrae is relatively nearby and also the right age to be forming planets. The star's protoplanetary disk contains more than enough mass to form one or more Jupiter-sized planets. A dusty disk like that in TW Hydrae tends to emit ...

... TW Hydrae to avoid a messy planetary construction site . Researchers at the Harvard - Smithsonian Center for Astrophysics have discovered that the gaseous disk surrounding TW Hydrae holds vast swaths of pebbles extending outward for at ...
... TW Hydrae association (Gizis 2002) shows excess. Gizis (2002) reported strong Hα emission (equivalent width ≈ 300 ̊A) from one of the TW Hydrae objects, the M8 dwarf 2MASSW J1207334-393254, and suggested it could be due to either ...
... TW Hydrae, in which dust-rich gas surrounds a star only a few million years old. ALMA's map of the distribution of the dust within this “protoplanetary disk” revealed notable gaps suggesting a “clearing-out” process similar to what ...
... TW Hydrae association . In this work we present the results for one of them , TW Hya , a Classical T Tauri star surrounded by a circumstellar disk . The disk has been imaged at different wavelengths ( e.g. Weinberger et al . 2002 ...
... TW Hydrae itself is a K8 dwarf with a likely mass of ∼0.6M ⊙. Overall, the association includes 7 known binaries and 2 triple systems in addition to the quadruple system, HD 98800; this represents a higher multiplicity frequency than ...
