HD 63021: Chromospheric Activity and Mass Transfer in a Close Binary
D. G. Whelan, S. D. Chojnowski, J. Labadie-Bartz +13
Prompted by X-ray detections from multiple surveys, we investigated the A-type star HD 63021 and found that it is a double-lined spectroscopic binary with highly variable emission…
The Importance of Telescope Training in Data Interpretation
D. G. Whelan, G. C. Privon, R. L. Beaton +8
In this State of the Profession Consideration, we will discuss the state of hands-on observing within the profession, including: information about professional observing trends; st…
WIYN Open Cluster Study. LXXV. Testing the Metallicity Dependence of Stellar Lithium Depletion Using Hyades-Aged Clusters. 1. Hyades & Praesepe
Jeffrey D. Cummings, Constantine P. Deliyannis, Ryan M. Maderak +1
WIYN/Hydra spectroscopy (at R~15,000) of the moderately metal-rich Praesepe and Hyades open clusters was used to study their main sequence (MS) iron ([Fe/H]) and lithium (A(Li)) ab…
Lithium Abundances of the Super-Metal-Rich Open Cluster NGC 6253
Jeffrey D. Cummings, Constantine P. Deliyannis, Barbara Anthony-Twarog +2
High-resolution CTIO 4-m/HYDRA spectroscopy of the super-metal-rich open cluster NGC 6253 ([Fe/H]=+0.43+/-0.01) has been used to study the stellar lithium (Li) abundances near the…
WIYN Open Cluster Study. XXXIX. Abundances in NGC 6253 from HYDRA Spectroscopy of the Li 6708 A Region
B. J. Anthony-Twarog, C. P. Deliyannis, B. A. Twarog +2
High-dispersion spectra of 89 potential members of the old, super-metal-rich open cluster, NGC 6253, have been obtained with the HYDRA multi-object spectrograph. Based upon radial-…
