  The (p,$\gamma$) cross sections of three stable Sr isotopes have been
measured in the astrophysically relevant energy range. These reactions are
important for the $p$-process in stellar nucleosynthesis and, in addition, the
reaction cross sections in the mass region up to 100 are also of importance
concerning the $rp$-process associated with explosive hydrogen and helium
burning. It is speculated that this $rp$-process could be responsible for a
certain amount of $p$-nuclei in this mass region. The (p,$\gamma$) cross
sections of $^{84,86,87}$Sr isotopes were determined using an activation
technique. The measurements were carried out at the 5 MV Van de Graaff
accelerator of the ATOMKI, Debrecen. The resulting cross sections are compared
with the predictions of statistical model calculations. The predictions are in
good agreement with the experimental results for $^{84}$Sr(p,$\gamma$)$^{85}$Y
whereas the other two reactions exhibit differences that increase with mass
number. The corresponding astrophysical reaction rates have also been computed.
