We consider the third order Benjamin-Ono equation on the torustu=x(xxu32uHxu32H(uxu)+u3). We prove that for any tR, the flow map continuously extends to Hr,0s(T) if s0, but does not admit a continuous extension to Hr,0s(T) if 0<s<12. Moreover, we show that the extension is weakly sequentially continuous in Hr,0s(T) if s>0, but is not weakly sequentially continuous in Lr,02(T). We then classify the traveling wave solutions for the third order Benjamin-Ono equation in Lr,02(T) and study their orbital stability.
