Comparison of the mean Hα line profile of Delorme 1 (AB)b to that of two young substellar objects with disks (left: CFHT BD Tau 4, center: ChaHa-1) and of a Class III 15 M_Jup brown dwarf (right: KPNO Tau 4). We scaled (in red) the profile of Ca Ha 1 to the free-fall velocities expected for Delorme 1 (AB)b. The profiles are similar to that of CFHS BD Tau 4 and ChaHa-1, but not to that of KPNO Tau 4.
