Summary: Let \(F\) be an irreducible binary form attached to a number field \(K\) of degree \(\geq 3\). Let \(\varepsilon\not\in \{-1, 1\}\) be a totally real unit of \(K\). By twisting \(F\) with the powers \(\varepsilon^a\) of \(\varepsilon\), (\(a\in\mathbb {Z}\)), we obtain an infinite family \(F_a\) of binary forms. Let \(m\in\mathbb {Z}\). We give an effective bound for \(\max\{|a|, \log|x|, \log|y|\}\) when \(a,x,y\) are rational integers satisfying \(F_a(x,y)=m\) with \(xy\not=0\).
