The First Post-Kepler Brightness Dips of KIC 8462852
Tabetha S. Boyajian, Roi Alonso, Alex Ammerman +203
We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometr…
Parent Stars of Extrasolar Planets. XII. Additional evidence for trends with vsini, condensation temperature, and chromospheric activity
Guillermo Gonzalez
Several recent studies have reported differences in vsini, abundance-condensation temperature trends, and chromospheric activity between samples of stars with and without Doppler-d…
The two metallicity groups of the globular cluster M22: a chemical perspective
A. F. Marino, C. Sneden, R. P. Kraft +11
We present a detailed chemical composition analysis of 35 red giant stars in the globular cluster M22. High resolution spectra for this study were obtained at five observatories, a…
Parent Stars of Extrasolar Planets. XI. Trends with Condensation Temperature Revisited
Guillermo Gonzalez, Melody Carlson, Ryan W. Tobin
We report the results of abundance analyses of new samples of stars with planets and stars without detected planets. We employ these data to compare abundance-condensation temperat…
Parent Stars of Extrasolar Planets. X. Lithium Abundances and vsini Revisited
G. Gonzalez, M. K. Carlson, R. W. Tobin
We determine Li abundances and vsini values from new spectra of 53 stars with Doppler-detected planets not included in our previous papers in this series. We also examine two sets…
