Generally,the number is at the high end of the planetary and nebula expansion range, but still within the observed range of velocities.
Hence, the larger stars must have lower escape velocities, whereas more massive stars must have higher escape velocities.
c) The white dwarfs are generally small, they may be located near the bottom of HR. Because it is white (i.e., hot), it would be located to the left. White dwarfs should be found below and to the left of main-sequence stars on the H-R diagram.
