orbiting planet. Instead, the data was better modelled by starspots on TW Hydrae's surface passing in and out of view as the star rotates. "Results support the spot scenario rather than the presence of a hot Jupiter around TW Hya". Similar wavelength-dependent radial velocity variations, also caused by starspots, have been detected on other T Tauri stars. New study of more distant planet In 2016, ALMA found evidence that a possible Neptune-like planet was forming in its disk, at a distance of around 22 AU. Detection of methanol In 2016, methanol, one of the building blocks for life, was detected in the star's protoplanetary disk.
