Exoplanetary Scratchpad

[SysBP Img]

T-Tauri star 450 ly away in the Taurus Molecular Cloud region that is only 100,000 years old that contains a protoplanet 14 times as massive as Jupiter and the youngest planet so far discovered. It was spotted as a clump and beat the previous youngest planet record holder (TW Hydrae) found earlier that year by a long shot, which was 10,000,000 years old. It was later the most precisely imaged protoplanetary disk, with rings and gaps clearly visible, indicating the formation of planets very early in the star formation process. Modeling suggests three Saturn-sized planets are required to form the grooves seen. It is accompanied by Herbig–Haro object HH 150, a jet of gas emitted along the rotational axis of the disk which is colliding with nearby interstellar dust and gas.
