The Vlasov theory of an electrostatic instability driven by a parabolic density gradient is considered. The magnetic field is taken as uniform, and the local approximation is used. The instability grows only for a sufficiently large, positive second derivative of the density. The parametric dependences of the linear growth rate are reported, as well as weakly nonlinear calculations on wave-particle transport due to this instability.
