A scenario of planet erosion by coronal radiation(Corrigendum)

Abstract

In the notes to Table 1, a unit conversion was incorrect. The text should read 1 M J Gyr -1 = 6.02e + 13 g s -1 . As a consequence in the 3rd paragraph of Sect. 3, the mass loss taking place in T Boo b should be M x = 0.011 M J Gyr -1 for p = 1 g cm -3 , or M x = 3.4 M ⊕ Gyr -1 in Earth mass units. Independently, the values of log F x accumulated, in Col. 12 of Table 1 were calculated using an obsolete formula and were thus slightly underestimated, generally by ≲0.2. As a consequence Fig. 2 should show all values at a slightly higher position, although this is of no relevance for the conclusions of the paper. Table 1 and Fig. 2 are reproduced in their correct version here. At the end of 5th paragraph of Sect. 2, the hard limit of X-ray flux accumulated after 10 Gyr should be ~10 22.14 erg cm -2 , instead of ~10 21.76 erg cm -2 , and our highest flux is now 10 21.23 erg cm -2 instead of 10 21.05 erg cm -2 .
