Updated Orbit and Observations of Spectroscopic Binary HD 2019.

FOWLER C., PLUFF III J. and THOMAS J.

Abstract (from CDS):

Binary star system HD 2019 was studied by the David Dunlap Observatory between 1935 and 1947. From the spectroscopic data obtained, the orbital elements of the system were defined. Between then and now, there have been no updated studies of this binary star system. We set out to update the orbit of HD 2019 with new spectroscopic data obtained at Clarkson University's Reynolds Observatory. After finding the radial velocities of the star or stars visible in each spectrum, estimates of the error for each measurement were made. From the radial velocities and error estimates, new orbital elements were fit using the data from David Dunlap Observatory combined with the new data collected at Clarkson. These results lead to further investigation of the eccentricity of the orbit. Using the method of Lucy 2005, we ran a test to check the statistical significance of the eccentric orbit using p-value testing.
