Revisiting the V Band Variance and Rotational Period of EK Dra
Research Mentor(s)
Davenport, James R. A., 1983-
Description
Although there are more stars in the sky than there are grains of sand on the all the beaches of the world, astronomers continue to gather information on many of the same stars. Due to the variation of stellar objects in long and short timescales it is necessary to revisit these stars to not only confirm but also to disprove earlier predictions and models. With additional data it is possible to create new and novel techniques to analyze their behavior. We have pieced together data from 4 different data sets to create a more complete picture of the variability in light of the microwave wavelength (V band) coming from EK Dra over a timescale spanning over 30 years. Four data sets were used to encompass a range from 1985 to 2015, with the longest data set spanning just over 15 years. From this data we look to better quantify and confirm a unique two period variation of the V band and rotational period of EK Dra as described by Messina and Guinan 2004 et al [1]. Such analysis from many years and catalogs of data opens the door for more complete and accessible data for future use in other research projects.
