Finding planets around T Tauri stars

Post by Lazarus on 23rd September 2008, 8:32 am

A Young Planet Search in Visible and IR Light: DN Tau, V836 Tau, and V827 Tau
Both DN Tau and V836 Tau show radial velocity variations, but it turns out they are caused by starspots. (Similar to the case with TW Hya). Turns out it is quite tricky to confirm planets around these stars: you need to make measurements at different wavelengths to test the starspot hypothesis.
