Reissner-Nordström perturbation framework with gravitational wave applications
Justin Y. J. Burton, Thomas Osburn
We present a new convenient framework for modeling Reissner-Nordström black hole perturbations from charged distributions of matter. Using this framework, we quantify how gravitati…
Spectroscopic characterization of the known O-star population in Cygnus OB2. Evidence of multiple star-forming bursts
S. R. Berlanas, A. Herrero, F. Comerón +6
Cygnus OB2 provides a unique insight into the high-mass stellar content in one of the largest groups of young massive stars in our Galaxy. Although several studies of its massive p…
Intermediate-to-Low Mass Stars in Open Clusters and the Evolution of Li
B. A. Twarog, B. J. Anthony-Twarog, C. P. Deliyannis +1
Open clusters (OC) of 1-3 Gyr age contain intermediate-to-low-mass stars in evolutionary phases of multiple relevance to understanding Li evolution. Stars leaving the main sequence…
WIYN Open Cluster Study LXXIX. M48 (NGC 2548) I. Radial Velocities, Rotational Velocities, and Metallicities of Stars in the Open Cluster M48 (NGC 2548)
Qinghui Sun, Constantine P. Deliyannis, Aaron Steinhauer +2
WIYN/Hydra spectra (R 13,500, signal-to-noise pixel = 50-1000) of a 400 $\unicode{x212B}$ region around Li 6708 $\unicode{x212B}$ are used to determine radial and rot…
WIYN Open Cluster Study LXXX: HDI CCD Photometry of the Old Open Cluster NGC 7142 and Comparison to M67
Qinghui Sun, Constantine P. Deliyannis, Bruce A. Twarog +2
We present photometry of 8702 stars in a field in the direction of NGC 7142, taken with the Half Degree Imager (HDI) at the WIYN 0.9-meter tele…
