A revised comparison of distant and nearby solar twins
Charles R. Cowley, Robert E. Stencel
Properties of solar twins reported by Lehmann et al. (2023) at kiloparsec distances from the local standard of rest (LSR) are compared to solar twins within 100 pc of the Sun. Thes…
Galactic chemical evolution]{Galactic chemical evolution of the solar neighborhood, solar twins and exoplanet indicators
Charles R. Cowley, Kutluay Yüce
Galactic chemical evolution (GCE), solar analogues or twins, and peculiarities of the solar composition with respect to the twins are inextricably related. We examine GCE parameter…
Modeling stellar abundance patterns resulting from the addition of earthlike planetary material
Charles R. Cowley, Donald J. Bord, Kutluay Yuce
The literature on precision differential abundances (PDAs) in stars is extensive. Surveys include sun-like stars in the solar neighborhood, binary systems, and Galactic clusters. N…
HD 196390: A tight correlation of differential abundances with condensation temperature
Charles R. Cowley, Donald J. Bord, Kutluay Yüce
Bedell et al. (2018) give precision differential abundances for 79 mostly G-dwarf stars. We correct these abundances for Galactic chemical evolution in a manner similar to that use…
Differential abundance analysis of Procyon and Theta Sculptoris: Comparison with abundance patterns of solar-like pairs
C. R. Cowley, K. Yüce, D. J. Bord
The precision differential abundance (PDA) technique is applied to the mid-F stars Procyon and Scl using spectra from the ESO UVESPOP library. We relate PDA patterns to endogen…
The Puzzling Spectrum of HD 94509
C. R. Cowley, N. Przybilla, S. Hubrig
The spectral features of HD 94509 are highly unusual, adding an extreme to the zoo of Be and shell stars. The shell dominates the spectrum, showing lines typical for spectral types…
