Astrometry is the branch of astronomy that measures the positions and apparent motions of celestial objects in the sky and the factors influencing them.

Double-star astrometry involves observing the position angles and separations of close double stars.

As part of this research project, you will use the 0.4m Las Cumbres Observatory, a network of robotic web-based telescopes, to observe a close double star listed in the Washington Double Star Catalog. You will then use software tools such as AstroImageJ or Afterglow Access to measure the position angle and separation distances between the primary and secondary stars.

You will also learn how to request historical records of the system to compare changes over time with your observations. Additionally, you will access Gaia data for the system to determine the nature of their gravitational binding.

As part of the project, you will draft a research paper to be submitted to the Journal of Double Star Observations for peer review and publication. You will also have the opportunity to present your results at conferences, either through talks or posters.
