Medium-resolution echelle spectroscopy of pulsating variables and   exoplanet host stars with sub-meter telescopes
  Here we present two of our interesting results obtained over the last 18 months from spectroscopic monitoring of binary pulsating stars and exoplanet host stars. Our investigations are very promising by demonstrating that modern fiber-fed spectrographs open a whole new chapter in the life of small national and university observatories.
