AbstractThe scientific program is presented as well a the abstracts of the contributions. An extended account is published in “The Ultraviolet Universe: stars from birth to death” (Ed. Gómez de Castro) published by the Editorial Complutense de Madrid (UCM), that can be accessed by electronic format through the website of the Network for UV Astronomy (www.ucm.es/info/nuva).There are five telescopes currently in orbit that have a UV capability of some description. At the moment, only FUSE provides any medium- to high-resolution spectroscopic capability. GALEX, the XMM UV-Optical Telescope (UVOT) and the Swift. UVOT mainly delivers broad-band imaging, but with some low-resolution spectroscopy using grisms. The primary UV spectroscopic capability of HST was lost when the Space Telescope Imaging Spectrograph failed in 2004, but UV imaging is still available with the HST-WFPC2 and HST-ACS instruments.With the expected limited lifetime of sl FUSE, UV spectroscopy will be effectively unavailable in the short-term future. Even if a servicing mission of HST does go ahead, to install COS and repair STIS, the availability of high-resolution spectroscopy well into the next decade will not have been addressed. Therefore, it is important to develop new missions to complement and follow on from the legacy of FUSE and HST, as well as the smaller imaging/low resolution spectroscopy facilities. This contribution presents an outline of the UV projects, some of which are already approved for flight, while others are still at the proposal/study stage of their development.This contribution outlines the main results from Joint Discussion 04 held during the IAU General Assembly in Prague, August 2006, concerning the rationale behind the needs of the astronomical community, in particular the stellar astrophysics community, for new UV instrumentation. Recent results from UV observations were presented and future science goals were laid out. These goals will lay the framework for future mission planning.

The Creation

AbstractProf. Jorge Sahade (1915–2012) was the first Latin American President of the International Astronomical Union (1985–1988). From then on, he had a very active participation as president, vice-president, and organizing committee member of several Commissions and Divisions of the IAU, related to stellar astrophysics and exchange of astronomers. Prof. J. Sahade was born in Argentina and was one of the first students graduated in astronomy at the National University of La Plata. He served as director of the Astronomical Observatory of Córdoba (1953–1955) and of the Observatory of La Plata (1968–1969). He was the first Dean of the Faculty of Exact Sciences of the National University of La Plata. He promoted the purchase of a 2.15-m diameter telescope, today located in the Complejo Astronómico El Leoncito, San Juan, Argentina. He founded the Institute of Astronomy and Physics of Space (IAFE) in Buenos Aires and was its first director (1971–1974). He was also director of the “Comisión Nacional de Actividades Espaciales” (the Argentina Space Activity Agency) and promoted the inclusion of Argentina as a partnership of the Gemini Observatory. Prof. Sahade also focused on the development of the astronomy in Latin America and this led to the creation of the “Liga Latinoamericana de Astronomía” (nowadays LIADA).His research field was interacting binary systems and he published about 150 papers, among them is the well-known discovery of the “Struve-Sahade effect”. I met him when he was 70 years old; he was a very enthusiastic astronomer, who travellled everywhere to promote the astronomy in Latin America (Argentina, Perú, Honduras). Among his last dreams was the creation of a Latin American Institute to develop and enhance astrophysics in South and Central America, the revival of UV astronomy and many more impressive works that he would have liked to end and publish.

One of the interesting results of ultraviolet (UV) astronomy was the discovery of ions from unexpected stages of ionization in spectra of O,B stars. The most common ions concerned are O VI and N V, but also C IV and Si IV in B stars. The presence of these ions is anomalous because generally their abundance is expected to be negligible if they are produced by photoionization by stellar radiation, either in the photosphere or in a cool circumstellar envelope (CE). The same ions are observed in the UV spectra of Be stars. Previous investigations, largely with Copernicus spectra, have reported O VI and N V in late Oe and early Be stars and Si IV in stars as cool as B5 (Marlborough, 1981 and references therein). In this paper we present the results of a preliminary survey of IUE spectra of Be stars covering a wide range of spectral type.

Near Future

Results from the IUE satellite, summarized in the section which follows this one, continue to dominate the literature for research topics which rely on observations in the ultraviolet. This trend may be accentuated in the near future, as we experience the natural attrition of papers based on results from previous major missions which are no longer operating, such as TD-1, Copernicus, ANS and BUSS. The Challenger accident on January 28, 1986 abruptly halted flights of new orbital facilities which depend on the Space Shuttle and has created long and somewhat indefinite postponements in the eventual manifesting of payloads ranging in size from simple experiments in Getaway Special (GAS) and Spartan carriers, to telescopes of intermediate size on Spacelab (such as those which were to fly on the Astro mission in March 1986) to the Hubble Space Telescope. Suborbital missions, i.e., sounding-rockets and balloons, will probably dominate the extra-IUE uv astronomy scene until there is a re-establishment of a vigorous launch schedule for expendable vehicles and/or the Space Shuttle.
