Medium-resolution echelle spectroscopy of pulsating variables and exoplanet host stars with sub-meter telescopes

摘要

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.
