# Errata

Page 49 [Added 12/04/10]
P.49, Equation 2.22, the 'J 'should not be in the subscript. The equation should read (in LaTeX):
\begin{equation}
\frac{\dot{M}_2}{M_2} = \frac{2 \dot{J}_{\rm sys}/J - (\dot{R}_2/R_2)_{\rm nuc}}{\zeta - \zeta_{\rm L}} \nonumber
\end{equation}

At the end of Worked Example 2.3, the equation on the penultimate line should have 1.42 on the top line not 2.82. The answer is correct though.

Page 139 [added 25/05/10]
P.139, second paragraph, the wavelength of the Lyman limit is 91.2 nm (or 912 Angstrom) not 912 nm.

Page 255 [Added 08/04/10]
P.255, solution to Exercise 1.12, the last sentence of the penultimate paragraph should say: "The first is in the ultraviolet range, the second is in the classical X-ray range."

In the solution to Exercise 6.5, in the penultimate equation (to calculate T), the exponent of the Boltzmann constant on the bottom line should be '-23' (not '23').

Page 276 [Added on 1/6/2010] In the solution to Exercise 7.9, the first term of the equation should have m2 on the top line (not m1).

Equation numbers in Solutions to Exercises [added 24/05/10]
The following equation numbers in the Solutions to Exercises are all re-used mistakenly, having referred to different equations in the body of the chapter:
In solution to Exercise 1.10, the equation labeled as 1.17 should be labeled as equation S1.1
In solution to Exercise 2.5, the equations labeled as 2.18 & 2.19 should be labeled as equations S2.1 & S2.2
In solution to Exercise 2.8, the equation labeled as 2.20 should be labeled as equation S2.3 (but label not needed)
In solution to Exercise 3.5, the equations labeled as 3.21 & 3.22 should be labeled as equations S3.1 & S3.2
In solution to Exercise 3.9, the equation labeled as 3.23 should be labeled as equation S3.3 (but label not needed)
In solution to Exercise 6.10, the equations labeled as 6.24 & 6.25 should be labeled as equations S6.1 & S6.2 (but labels not needed)
In solution to Exercise 7.10, the equations labeled as 7.26 & 7.27 should be labeled as equations S7.1 & S7.2 (but labels not needed) Ulrich Kolb's home page. Astronomy Research at the OU.
