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 18months from spectroscopic monitoring of binary pulsating stars and exoplanethost stars. Our investigations are very promising by demonstrating that modernfiber-fed spectrographs open a whole new chapter in the life of small nationaland university observatories.
