    The Hubble Space Telescope (HST) Treasury Program on the Orion Nebula Cluster (ONC) has used 104 orbits of HST time to image the Great Orion Nebula region with the Advanced Camera for Surveys (ACS), the Wide-Field/Planetary Camera 2 (WFPC2), and the Near-Infrared Camera and Multi-Object Spectrograph (NICMOS) instrument in 11 filters ranging from the U band to the H band equivalent of HST. The program has been intended to perform the definitive study of the stellar component of the ONC at visible wavelengths, addressing key questions like the cluster initial mass function, age spread, mass accretion, binarity, and cirumstellar disk evolution. The scanning pattern allowed us to cover a contiguous field of approximately 600 arcmin^2 with both ACS and WFPC2, with a typical exposure time of approximately 11 minutes per ACS filter, corresponding to a point source depth AB(F435W) = 25.8 and AB(F775W) = 25.2 with 0.2 mag of photometric error. We describe the observations, data reduction, and data products, including images, source catalogs, and tools for quick look preview. In particular, we provide ACS photometry for 3399 stars, most of them detected at multiple epochs; WFPC2 photometry for 1643 stars, 1021 of them detected in the U band; and NICMOS JH photometry for 2116 stars. We summarize the early science results that have been presented in a number of papers. The final set of images and the photometric catalogs are publicly available through the archive as High Level Science Products at the STScI Multimission Archive hosted by the Space Telescope Science Institute

    Discovery of new members of the nearby young stellar association in Cepheus

    Get PDF
    Context. Young field stars are hardly distinguishable from older ones because their space motion rapidly mixes them with the stellar population of the Galactic plane. Nevertheless, a careful target selection allows for young stars to be spotted throughout the sky. Aims. We aim to identify additional sources associated with the four young comoving stars that we discovered towards the CO Cepheus void and to provide a comprehensive view of the Cepheus association. Methods. Based on multivariate analysis methods, we have built an extended sample of 193 young star candidates, which are the optical and infrared counterparts of ROSAT All-Sky Survey and XMM-Newton X-ray sources. From optical spectroscopic observations, we measured their radial velocity with the cross-correlation technique. We derived their atmospheric parameters and projected rotational velocity with the code ROTFIT. We applied the subtraction of inactive templates to measure the lithium equivalent width, from which we infer their lithium abundance and age. Finally, we studied their kinematics using the second Gaia data release. Results. Our sample is mainly composed of young or active stars and multiple systems. We identify two distinct populations of young stars that are spatially and kinematically separated. Those with an age between 100 and 300 Myr are mostly projected towards the Galactic plane. In contrast, 23 of the 37 sources younger than 30 Myr are located in the CO Cepheus void, and 21 of them belong to the stellar kinematic group that we previously reported in this sky area. We report a total of 32 bona fide members and nine candidates for this nearby (distance = 157±10 pc) young (age = 10–20 Myr) stellar association. According to the spatial distribution of its members, the original cluster is already dispersed and partially mixed with the local population of the Galactic plane

    Rebellion in the ‘Near North’ The response of the Australian Government to the Indonesian Outer-Island Rebellion, 1956-1959.

    Get PDF
    This thesis focuses on the response of the Australian government to the outbreak of the Indonesian Outer-Island rebellion and the American intervention-through the CIA- to support the rebels against the Central Government in Jakarta. The Australia-Indonesia bilateral relationship is considered one of Australia’s most crucial diplomatic relationships. This thesis will situate the Australian response to the rebellion within the historical context of Australia’s post-1945 engagement with Asia, the Cold War, and the process of decolonisation in Southeast Asia. Drawing on a variety of Australia and American primary sources, including diplomatic cables, government memoranda, private letters, press releases, reports, oral histories, and newspapers, the thesis will analysis how Australian politicians, diplomats and military officials dealt with a major foreign policy crisis in what Prime Minister Menzies called the “near north”

    Adaptive Reuse

    The present volume explores a specific aspect of creativity in South Asian systems of knowledge, literature and rituals. Under the heading of “adaptive reuse,” it discusses the relationship between innovation and perpetuation of earlier forms and contents of knowledge and aesthetic expressions within the process of creating new works. Although this relation rarely became the topic of explicit reflections in the South Asian intellectual traditions, it is here investigated by taking a closer look at the treatment of older materials by later authors."Adaptive Reuse" ist ein wichtiges theoretisches Konzept aus dem Bereich der Architektur. Dort bezeichnete es die Verwendung eines teilweise umgebauten Gebäudes zu andern Zwecken als denen seiner ursprünglichen Errichtung. Im vorliegenden Band wird dieses Konzept zum ersten Mal auf ein weiteres Spektrum kulturellen Schaffens übertragen, nämlich auf die Komposition von Texten und auf die Kreation neuer Konzepte und Ritual
