We know for sometime that nuclear forces and phenomena are the origin of

chemical elements in the Universe and are the fuel of the stars. To

quantitatively describe the processes involved we need more and better

nuclear data. These are being obtained either using direct measurements at

small acelerators and reactions at energies close to the ones involved in

stars, or through a select number of indirect methods with reactions at much

larger energies, which can then be translated in reaction rates at stellar

temperatures. I will briefly describe the most usual of the methods, with

examples from cases studied in my own group of young nuclear

astrophysicists: ion-ion fusion, Coulomb Dissociation, nuclear breakup,

transfer reactions, beta-delayed proton-decay, etc. Using IFIN-HH small

accelerators & an undergraound laboratory, or radioactive ion beams at

international laboratories.
