Solar Analogs and HERMES spectrograph

HERMES Spectrograph at MERCATOR close to the heavens Solar Analogs from KEPLER Mission observed with HERMES spectrograph  at MERCATOR Observatory  at Canary Islands, Spain. Solar-analog stars provide an excellent opportunity to study the Sun’s evolution, i.e. the changes with time in stellar structure, activity, or rotation for solar-like stars. The unparalleled photo-metric data from the NASA space telescope Kepler allows us to study and characterize solar-like stars through asteroseismology. We aim to spectroscopically investigate the fundamental parameter and chromospheric activity of solar analogues and twins,based on observations obtained with the Hermes spectrograph and combine them with asteroseismology. Therefore, we need to build a solar atlas for the spectrograph, to provide accurate calibrations of the spectroscopically determined abundances of solar and late type stars observed with this instrument and thus perform differential spectral comparisons.We acq
