This book records our current understanding of the observational and theoretical properties of objects known as ultracool dwarfs. It covers the state of the art in this new field. It is split into theoretical, observational and spectral classification sections. Each subject area begins with an introduction by an eminent scientist. It covers a wide range of issues, such as the transition from L to T dwarfs, dust and alkali metal modelling, companions, activity, the deuterium test, and brown dwarf variability, and contains considerable discussion about spectral classification schemes. The articles arose from an IAU meeting and they address researchers as well as graduate students.

An African American art form, jazz dance has an inaccurate historical narrative that often sets Euro-American aesthetics and values at the inception of the jazz dance genealogy. The roots were systemically erased and remain widely marginalized and untaught, and the devaluation of its Africanist origins and lineage has largely gone unchallenged. Decolonizing contemporary jazz dance practice, this book examines the state of jazz dance theory, pedagogy, and choreography in the twenty-first century, recovering and affirming the lifeblood of jazz in Africanist aesthetics and Black American culture.Rooted Jazz Dance brings together jazz dance scholars, practitioners, choreographers, and educators from across the United States and Canada with the goal of changing the course of practice in future generations. Contributors delve into the Africanist elements within jazz dance and discuss the role of Whiteness, including Eurocentric technique and ideology, in marginalizing African American vernacular dance, which has resulted in the prominence of Eurocentric jazz styles and the systemic erosion of the roots. These chapters offer strategies for teaching rooted jazz dance, examples for changing dance curriculums, and artist perspectives on choreographing and performing jazz. Above all, they emphasize the importance of centering Africanist and African American principles, aesthetics, and values. Arguing that the history of jazz dance is closely tied to the history of racism in the United States, these essays challenge a century of misappropriation and lean in to difficult conversations of reparations for jazz dance. This volume overcomes a major roadblock to racial justice in the dance field by amplifying the people and culture responsible for the jazz language.

Once you have looked at the night sky on a moonless night it is not hard to realise why so much of our science and religion has its roots in the stars. Yet it took until 1850 to realise that fainter stars were not necessarily further away, nor the brighter ones closer. In fact within the magnitude range observable to the naked eye it is probable that the brighter star is in fact further away. Even today the measurement of stellar distances is relatively difficult and is gener ally only done using dedicated telescopes. In the early years of the 20th century Hertzsprung and Russell developed a powerful classification diagram which al lows stars to be distinguished using a plot of their colour versus magnitude. The construction of this diagram involved the use of spectroscopy which has become the cornerstone of modern astronomy. As telescopes become more powerful, de tectors more sensitive and more physics is added to astrophysics, astronomical spectroscopy becomes a more powerful tool. The concern of this book is the spectral classification of stars. With a single spectrum of a star it is possible to uniquely classify an object and find its place on the Hertzsprung-Russell diagram. This spectrum is thus equivalent to having the colour and the magnitude of the object which can in turn be related to mass and other quantities."
