Especially rewarding<br class="">targets are solar-oscillators. This group populates the full range of stellar evolution between the main sequence and various red-giant phases. Vital to the interoperation of space photometry is ground-based<br class="">spectroscopy, which benefits from new observing facilities, such as the Mercator telescope. In this talk we will discuss the major advances in observations and theory that have been achieved from space photometry and underline the role of double-lined binaries for the understanding of stellar physics. In particular two cases of red giant binary systems are presented, for which we combine the techniques of seismic analysis and spectral disentangling. By doing so, we can investigate changes of fundamental parameters and stellar abundance pattern between the two stellar components and study stars, as a function of their mass difference and watch stellar evolution in action.<div class=""><br class=""></div><div class="">If you have recently read interesting astrophysics paper you would like to present, please contact me via e-mail: <a href="mailto:lceraj@phy.hr" class="">lceraj@phy.hr</a></div><div class=""><br class=""></div><div class=""><div class="">See you all on Friday.</div><div class=""><br class=""></div><div class="">Cheers,</div><div class="">Lana</div></div></body></html>
