High-precision abundances of elements in solar-type stars. Evidence of two distinct sequences in abundance-age relations

P. E. Nissen, J. Christensen-Dalsgaard, J. R. Mosumgaard +3

HARPS spectra with signal-to-noise ratios S/N > 600 at 6000 A were analysed with MARCS model atmospheres to obtain 1D LTE abundances of C, O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Sr…

Doppler imaging and differential rotation of $σ^{2}$ Coronae Borealis using SONG

Yue Xiang, Shenghong Gu, A. Collier Cameron +6

We present new Doppler images of both components of the double-lined binary $σ^{2}$ CrB, based on the high-resolution spectroscopic data collected during 11 nights in 2015 March--A…
