RESUMO Nascido nas regiões próximas à Roma, entre 85 a 80 a.e.c. Vitrúvio redigiu a obra Dez Livros de Arquitetura. O período, possivelmente, data entre o final da República e o começo do principado de Augusto. Entre 29 a 27 a.e.c, após ter escrito o texto principal da obra, Vitrúvio vê a necessidade de prefaciar e dedicar seu tratado para Augusto César. Inserido nessa acentuada movimentação política, Vitrúvio publica, em 27 a.e.c. sua obra. Para Vitrúvio, a ciência do arquiteto é ornada de muitas disciplinas e de vários saberes, sendo necessário ter conhecimento em arte literária, ciência do desenho, geometria, aritmética, fatos históricos, filosofia, música, medicina e astronomia, pois todas essas disciplinas tem, entre si, ligação e comunicação. De fato, Vitrúvio prova na sua obra que era munido de todos esses saberes. Dos Dez Livros de Arquitetura, o livro 9 é dedicado para a Astronomia, objetivando a compreensão do sistema dos relógios solares. A complexa construção do seu analema, uma pré construção dos relógios solares, traz consigo diversos conceitos de Astronomia praticados na época. E foi com base nesses conceitos que determinamos o ano de 47 a.e.c. como sendo o ano de redação do nono livro. Além disso, através do debate histórico ocorrido entre os estudiosos vitruvianos, determinamos o ano em que Vitrúvio nasceu, faleceu, redigiu, prefaciou e dedicou sua obra. Apresentamos, no primeiro capítulo, um resumo dos Dez Livros de Vitrúvio, as diferentes trajetórias das edições vitruvianas durante os séculos IX até apresente data e 16 edições que consideramos significativas para qualquer estudioso vitruviano. No segundo capítulo, analisamos o processo histórico sobre o debate entre os estudiosos, referente à data que Vitrúvio viveu e redigiu sua obra. No terceiro capítulo, analisamos o livro 9, objetivando localizar conteúdos de Astronomia descritos por Vitrúvio, os quais, mais a frente, nos auxiliaram a concluir a determinação do ano que ele redigiu esse livro. Por fim, no capítulo 4, a conclusão é realizada com base nos estudos dos teóricos apresentados no capítulo 2 e dos conceitos de Astronomia apresentados no capítulo 3, determinamos o ano que Vitrúvio nasceu, faleceu, redigiu, prefaciou e dedicou sua obra. Palavras Chaves: História da Ciência, Vitrúvio, Astronomia. ABSTRACT Born in the surrounding areas of Rome between 85 and 80 BC, Vitruvius has written The Ten Books on Architecture. The period, possibly, dates between the end of the Republic and the beginning of Augustus’ principality. Between 29 and 27 BC, after had written the main text of his work, Vitruvius saw the need of preface and dedicate his treaty to Augustus Caesar. Inserted on this accented political movement, Vitruvius publishes, in 27 BC, his work. For Vitruvius, the science of the architect is compounded by several disciplines and different types of knowledge, being necessary have acquaintance in literary art, science of drawing, geometry, arithmetic, historical facts, philosophy, music, medicine and astronomy, since all this disciplines have, among them, connection and communication. In fact, Vitruvius proofs on its work that managed all these knowledge areas. From The Ten Books on Architecture, the book 9 is dedicated to Astronomy, objectifying the comprehension of sundials systems. The complex construction of its analemma, a pre-construction of the sundials, brings several Astronomy concepts practiced on that time. And based on these concepts we determined the year of 47 BC as the year the ninth book was written. Besides, through the historical debate occurred among the vitruvian scholars, we determined the year Vitruvius has born, died, written, prefaced and dedicated his work. We present, in the first chapter, an abstract of the Ten Books of Vitruvius, the different trajectories of the vitruvian editions since the IX century until the present date and 16 editions we consider significant for any vitruvian scholar. In the second chapter, we analyze the historical process about the debate among scholars, referent to the date Vitruvius lived and wrote his work. In the third chapter, we analyzed the book 9, objectifying localize Astronomy contents described by Vitruvius, of which, thereafter, assisted us to conclude which year he wrote this book. Finally, in the chapter 4, the conclusion is made based on the studies of theorists presented in the chapter 2 and the concepts of Astronomy presented in chapter 3, we determined the year Vitruvius has born, died, written, prefaced and dedicated his work.

WALBORNt Space Telescope Science Institute, φ 3700 San Martin Drive, Baltimore, Maryland 21218 AND EDWARD L. FITZPATRICKf Princeton University Observatory, Peyton Hall, Princeton, New Jersey 08544 Received 1990 ABSTRACT Some recent developments in the optical classification of OB spectra are reviewed in terms of a comprehensive atlas of new blue-violet digital data from the CTIO 1-meter photon-counting system. These developments include the OS spectral type; luminosity criteria for the O stars; OBN/OBC anomalies; and refined, interpolated late-O/early-B types. Examples of these phenom- ena are included among extensive spectral- and luminosity-class sequences, comprising 75 standard objects arranged into 27 montages and covering the wavelength range 3950 Â-4750 A for types OS-BS (-B8 at Iö). It is intended that this atlas serve a reference function analogous to that of the printed MK atlases, for morphological investigations of OB spectra based on digital data, which will supersede photographic techniques in most future applications.

John A. Eddy, The New Solar Physics (1977-78) Foreword By E. N. Parker In this time of global warming we are impelled by both the anticipated dire consequences and by scientific curiosity to investigate the factors that drive the climate. Climate has fluctuated strongly and abruptly in the past, with ice ages and interglacial warming as the long term extremes. Historical research in the last decades has shown short term climatic transients to be a frequent occurrence, often imposing disastrous hardship on the afflicted human populations.

Hutcheon Submitted in accordance with the requirements for the degree of Doctor of Philosophy. Research Institute: School of Environmental and Physical Sciences and Applied Mathematics. University of Keele June 2015 ii iii Abstract This thesis is in three parts: 1) a kinematical study of exoplanet host stars, 2) a study of the detached eclipsing binary V1094 Tau and 3) and observations of other eclipsing binaries. Part I investigates kinematical biases between two methods of detecting exoplanets; the ground based transit and radial velocity methods. Distances of the host stars from each method lie in almost non-overlapping groups. Samples of host stars from each group are selected. They are compared by means of matching comparison samples of stars not known to have exoplanets. The detection methods are found to introduce a negligible bias into the metallicities of the host stars but the ground based transit method introduces a median age bias of about -2 Gyr.

This book can be referenced as follows: Reipurth, B. 2016, http://ifa.hawaii.edu/SP1 i FOREWORD I first learned about George Herbig’s work when I was a teenager. I grew up in Denmark in the 1950s, a time when Europe was healing the wounds after the ravages of the Second World War. Already at the age of 7 I had fallen in love with astronomy, but information was very hard to come by in those days, so I scraped together what I could, mainly relying on the local library. At some point I was introduced to the magazine Sky and Telescope, and soon invested my pocket money in a subscription. Every month I would sit at our dining room table with a dictionary and work my way through the latest issue. In one issue I read about Herbig-Haro objects, and I was completely mesmerized that these objects could be signposts of the formation of stars, and I dreamt about some day being able to contribute to this field of study.
