This Symposium begun with a suggestion for a gathering to honour Emer­ itus Professor Robert Hanbury Brown at the celebration of his eightieth birthday. He asked that this type of assembly can be on a subject that may be of gain to the Sydney collage Stellar Interferometer (SUSI) software. With SUSI and several excessive angular solution tools both in operation or approaching line in the subsequent decade, and with advances in astrometry, spectroscopy and in theoretical types of stellar atmospheres and interiors, it looked to be either applicable and well timed to carry a symposium on "Fundamental Stellar houses: the interplay among commentary and conception. " The emphasis of the assembly used to be at the severe evaluate of the qual­ ity, accuracy, and customers for development of the observational facts and theoretical types, at the amazing difficulties in stellar astrophysics, and at the feasibility of accomplishing the observational and theoretical advances required for his or her answer. Invited papers comprised the key a part of the oral software and the audio system replied to the problem issued via the clinical setting up Committee to significantly evaluation the present prestige and customers for his or her distinctiveness. The Symposium used to be opened by way of the Chancellor of the collage of Sydney, Emeritus Professor Dame Leonie Kramer, who welcomed the 126 individuals from 22 international locations on behalf of the college. The oral software integrated . fifty two invited studies and papers and 10 contributed papers.
