TW Hydrae
(TW Hya)
(nearest T-Tauri star)
TW Hydrae (TW Hya) is the nearest T-Tauri star to the Sun,
and is the star for which TW Hydrae association is named.
It has a face-on protoplanetary disk, that has a gap
suggesting a likely extra-solar planet, which would be TW Hydrae b,
with a mass of up to about 1.5 Neptune masses, i.e.,
roughly 25 Earth masses. (A discounted study had
theorized a more massive planet based on other arguments.)
