  • Two Hα emission peaks are detected within the disk of the T Tauri star PDS 70: one corresponds to protoplanet PDS 70 b, and the other is associated with a second accreting planet of few Jupiter masses at ~35 au. The two protoplanets are near 2:1 mean motion resonance, supporting migration scenarios of giant planets during planetary formation.

  • There is a general consensus that planets form within disks of dust and gas around newly born stars. However, the timescale of planet formation remains unclear. The detection of a planet of mass 9.8 ± 3.3 MJupiter around TW Hydrae, a nearby young star with an age of only 8–10 Myr, orbiting with a period of 3.56 days is reported. This demonstrates that planets can form within 10Myr, before the disk has been dissipated by stellar winds and radiation.
