The paper ‘A self-similar solution for thermal disc winds’ by Clarke & Alexander, published in 2016, MNRAS 460,3044, contained typographical errors in the following equations whose corrected forms are given below:
(7)
(8)
(17)
and
(18)

In addition, the first paragraph of Section 3.1 should be replaced by the following:

We consider solutions for which |$\tilde{x} =1, \tilde{y} =0$| and |$\tilde{x} ^\prime = 0$| at the flow base. In this case the limiting value of |$\tilde{u}^\prime$| near the flow base is |$b \tilde{y}/({\cal M}_b^2 (1 - {\cal M}_b^2))$|⁠, where |${\cal M}_b$| is the Mach number at the flow base, so that for subsonic launch velocities the flow accelerates for finite |$\tilde{y}$|⁠. At large radius, the flow becomes increasingly radial [i.e. |$(1 - \tilde{y} \tilde{x} ^\prime /\tilde{x})$| tends to 0] so that the second term in g can be neglected and the limiting form of g is
(21)

The first term in f (equation (17)) is negative in the supersonic regime whereas g and the second term in f are both positive.

From this point on the paper is unchanged. The errors were all typographical in nature and did not affect the equations used in the analysis so that the results are not changed by these corrections. The authors apologize for these errors and thank Mark Hutchison for bringing them to our attention. The preprint on the arXiv has been updated accordingly.
