Research interests of Observatory staff currently focus on (i) Stellar and Galactic Astrophysics (including star formation, astrophysical jets, cool stars, hot stars, and helium stars), (ii) the Sun (the dynamic solar atmosphere, chromosphere and corona), (iii) Solar System Astronomy (including celestial mechanics, planetary science, and the dynamical evolution and interrelationships of comets, asteroids, meteoroids and interplanetary dust), and (iv) Solar System - Terrestrial Relationships (including solar variability, climate, accretion of interplanetary dust and NEOs). In addition, Armagh Observatory staff participate in an active programme of education and lifelong learning via lectures, popular astronomy articles and interviews with the press, radio and television. Further details concerning the research interests of the Observatory staff may be obtained from the Observatory web-site at: http://star.arm.ac.uk/.
A subset of the Observatory's research activity, namely the list of 41 refereed journal publications during 2004 and one book, is given in Appendix C. A related subset, namely the list of 93 public and professional presentations delivered by Observatory staff during 2004, is given in Appendix D, while a third subset -- the list of Observatory seminars -- is given in Appendix E.
These examples illustrate some of the routes by which research results are received and communicated to others by Observatory staff: through public talks or articles in the local, national or international media; at conferences, seminars and workshops; in refereed scientific publications and journals; in books; and in a variety of non-refereed publications.
The remainder of this section first summarises a few highlights of the Observatory's research and other activities during 2004, and then, under the headings of the Observatory's senior research staff, presents lay reports of some of the principal research and related activities undertaken by these staff and their colleagues during 2004. Full details can be obtained by referring to the refereed and other journal publications of Observatory staff, available on the internet.
