Research interests of Observatory staff currently focus on (i) Stellar Astrophysics (including star formation, astrophysical jets, cool stars, hot stars, helium stars, star-spots, flares, circumstellar dust), (ii) the Sun (the dynamic solar atmosphere, chromosphere and corona), (iii) Solar System Astronomy (including celestial mechanics, the dynamical evolution and relationships between comets, asteroids and interplanetary dust), and (iv) Solar System - Terrestrial Relationships (including solar variability, climate, accretion of interplanetary dust and Near-Earth Objects). In addition, Observatory staff maintain an active programme of Public Understanding of Science (PUS), via lectures, popular astronomy articles, the provision of advice to the general public, Observatory tours, and interviews with the press, radio and television.
Staff at the Observatory have also investigated (i) the structure of meteor streams; (ii) an apparently regular periodicity in some extragalactic redshifts; and (iii) the role played by the variable Sun on climate change during the past two hundred years. The Armagh climate series, which is one of the longest in the world from a single site, can now be accessed over the internet by individuals, schools, and researchers from anywhere in the world (see climate.arm.ac.uk). Further details concerning the research interests of all the Observatory staff may be obtained from the Observatory web-site at: star.arm.ac.uk.
