We derive a self-consistent set of atmospheric parameters and abundances of 17 elements for the red giant star Arcturus: T= 4286 ± 30 K, log g = 1.66 ± 0.05, and [Fe/H] = –0.52 ± 0.04. The effective temperature was determined using model atmosphere fits to the observed spectral en...
This star shows a relative overabundances of Ca and Ba, and underabundances of Na, V and Ni with respect to the solar mix. Activity of the star is indicated by the filled in H★ and Caii triplet line cores. It has been confirmed that our spectroscopic approach yields fairly reliable ...

Advanced prostate cancer initially responds to hormonal treatment, but ultimately becomes resistant and requires more potent therapies. One mechanism of resistance observed in around 10–20% of these patients is lineage plasticity, which manifests in a p
