Our paper discussing the YORP torques on ellipsoids of revolution (Breiter et al. 2007) contains three incorrectly typeset equations: (79) and (106) have wrong signs, whereas (105) has a wrong factor 2 instead of $\frac{1}{2}$ . The correct form of the equations is

$\begin{displaymath}% v_2 = -\,\frac{1}{12}\,\left(9- 5 x_\odot^2 \right), \end{displaymath}$

(79)

$\begin{displaymath}% \langle T_\bot \rangle = -\frac{1}{2}\, \alpha'\,\sin{\vare... ...\varepsilon}\,\sin{\delta} \sum_{j \geq 1} {\rm e}^{2j}\,c_j, \end{displaymath}$

(105)

$\begin{displaymath}% c_2 = -\frac{1}{64}\,(28+ 15 \sin^2\varepsilon). \end{displaymath}$

(106)

In a recent paper (Breiter & Michalska 2008) we also show how to convert the results obtained by means of the simplistic ``delayed Sun'' approach to a more realistic thermal lag model.
