Sequential Chomospheric Brightening: An Automated Approach to Extracting Physics from Ephemeral Brightening
Michael S. Kirk, K. S. Balasubramaniam, Jason Jackiewicz +2
We make a comparison between small scale chromospheric brightenings and energy release processes through examining the temporal evolution of sequential chromospheric brightenings (…
The Classificiation of Kepler B star Variables
Bernard J. McNamara, Jason Jackiewicz, Jean McKeever
The light curves of 252 B-star candidates in the Kepler data base are analyzed in a similar fashion to that done by Balona et al. (2011) to further characterize B star variability,…
An Automated Algorithm to Distinguish and Characterize Solar Flares and Associated Sequential Chromospheric Brightenings
M. S. Kirk, K. S. Balasubramaniam, J. Jackiewicz +2
We present a new automated algorithm to identify, track, and characterize small-scale brightening associated with solar eruptive phenomena observed in Hα. The temporal spatially-lo…
A Possible Period for the K-band Brightening Episodes of GX 17+2
Jillian Bornak, Bernard J McNamara, Thomas E Harrison +3
The low mass X-ray binary and Z source GX 17+2 undergoes infrared K-band brightening episodes of at least 3.5 magnitudes. The source of these episodes is not known. Prior published…
The Behaviour of the Optical and X-ray Emission from Scorpius X-1
B. J. McNamara, T. E. Harrison, R. T. Zavala +11
In 1970, Hiltner & Mook reported the results of the first multiyear study of the optical emission from Sco X-1. They found that the Sco X-1 B-magnitude histograms changed from year…
The origin of cyclic period changes in close binaries: the case of the Algol binary WW Cygni
Robert T. Zavala, Bernard J. McNamara, Thomas E. Harrison +11
Years to decade-long cyclic orbital period changes have been observed in several classes of close binary systems including Algols, W Ursae Majoris and RS Canum Venaticorum systems,…
