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…
Sustaining educational and public outreach programs in astronomy
William I. Clarkson, Donald J. Bord, Carrie M. Swift +7
We advocate meaningful support of sustained education-outreach partnerships between regional metropolitan undergraduate institutions and astronomical clubs and societies. We presen…
Reverberation Mapping of the Seyfert 1 Galaxy NGC 7469
B. M. Peterson, C. J. Grier, Keith Horne +43
A large reverberation mapping study of the Seyfert 1 galaxy NGC 7469 has yielded emission-line lags for Hbeta 4861 and He II 4686 and a central black hole mass measurement of about…
The Structure of the Broad Line Region in AGN: I. Reconstructed Velocity-Delay Maps
C. J. Grier, B. M. Peterson, Keith Horne +38
We present velocity-resolved reverberation results for five active galactic nuclei. We recovered velocity-delay maps using the maximum-entropy method for four objects: Mrk 335, Mrk…
