Aim. The outer atmosphere of K giants shows thermally inhomogeneous structures consisting of the hot chromospheric gas and the…
Abundance of iron in the atmosphere of Arcturus has been determined from the profiles or regions of the profiles of the weak…
We derive a self-consistent set of atmospheric parameters and abundances of 17 elements for the red giant star Arcturus: Teff…
Context. Arcturus is the second closest K giant and among the brightest stars in the sky. It has not been found to have a…
The spectroscopic variability of Arcturus hints at cyclic activity cycle and differential rotation. This could provide a test of…
We used spectral observations of Fe I line profiles with a 200 000 resolution to determine micro and macroturbulent velocities in…
Abstract The Arcturus moving group is a well-populated example of phase space substructure within the disk of our Galaxy. With…
Aims. The fast improvement of spectroscopic observations makes mandatory a strong effort on the theoretical side to better…
We have modeled absorption lines of the 12CO and 13CO (Δυ = 2) molecular bands at λλ 2.29–2.45 µm in the spectrum of Arcturus…
We compare IUE far-ultraviolet and Einstein soft X-ray observations of the red giant Arcturus (..cap alpha.. Booetis, K2III) and…
