Zeeb Road, Ann Arbor, MI 48106 INFORMATION TO USERS This reproduction was made from a copy of a manuscript sent to us for publication and microfilming. While the most advanced technology has been used to pho­ tograph and reproduce this manuscript, the quality of the reproduction is heavily dependent upon the quality of the material submitted. Pages in any manuscript may have indistinct print. In all cases the best available copy has been filmed. The following explanation of techniques is provided to help clarify notations which may appear on this reproduction. 1. Manuscripts may not always be complete. When it is not possible to obtain missing pages, a note appears to indicate this. 2. When copyrighted materials are removed from the manuscript, a note ap­ pears to indicate this. 3. Oversize materials (maps, drawings, and charts) are photographed by sec­ tioning the original, beginning at the upper left hand comer and continu­ ing from left to right in equal sections with small overlaps. Each oversize page is also filmed as one exposure and is available, for an additional charge, as a standard 35mm slide or in black and white paper format.* 4. Most photographs reproduce acceptably on positive microfilm or micro­ fiche but lack clarify on xerographic copies made from the microfilm. For an additional charge, all photographs are available in black and white standard 35mm slide format.

  • Extrasolar Planets and Their Host Stars
    Kaspar von Braun & Tabetha S. Boyajian Extrasolar Planets and Their Host Stars July 25, 2017 arXiv:1707.07405v1 [astro-ph.EP] 24 Jul 2017 Springer Preface In astronomy or indeed any collaborative environment, it pays to figure out with whom one can work well. From existing projects or simply conversations, research ideas appear, are developed, take shape, sometimes take a detour into some un- expected directions, often need to be refocused, are sometimes divided up and/or distributed among collaborators, and are (hopefully) published. After a number of these cycles repeat, something bigger may be born, all of which one then tries to simultaneously fit into one’s head for what feels like a challenging amount of time. That was certainly the case a long time ago when writing a PhD dissertation. Since then, there have been postdoctoral fellowships and appointments, permanent and adjunct positions, and former, current, and future collaborators. And yet, con- versations spawn research ideas, which take many different turns and may divide up into a multitude of approaches or related or perhaps unrelated subjects. Again, one had better figure out with whom one likes to work. And again, in the process of writing this Brief, one needs create something bigger by focusing the relevant pieces of work into one (hopefully) coherent manuscript. It is an honor, a privi- lege, an amazing experience, and simply a lot of fun to be and have been working with all the people who have had an influence on our work and thereby on this book. To quote the late and great Jim Croce: ”If you dig it, do it.

    Ma¯lamalama 1 ma¯lamalamaTHE LIGHT OF KNOWLEDGE www.hawaii.edu/malamalama Editor Cheryl Ernst Medal honors faculty members who transform students’ lives Art Director Aloha! For 99 years, the University of Hawai‘i has done more than any institution Rowen Tabusa (BFA ’79 Ma¯noa) in our state to transform our citizens’ lives and thereby Hawai‘i itself. The “DNA” Photographer Bob Chinn of this transformational enterprise lies in the hearts and Associate Editor minds of a remarkable faculty—expert and enthusiastic Tracy Matsushima (BA ’90 Ma¯noa) about their subjects and able to connect with learners of Online Editor all ages and backgrounds. Jeela Ongley (BA ’97 Ma¯noa) On Sept. 19 we celebrate some of these scholars—the Contributing Alumni Editor Nico Schnitzler (BA ’03 Ma¯noa) 2006 recipients of the Regents’ Award for Excellence in University of Hawai‘i President Teaching.

  • Constellations
    Your Guide to the CONSTELLATIONS INSTRUCTOR'S HANDBOOK Lowell L. Koontz 2002 ii Preface We Earthlings are far more aware of the surroundings at our feet than we are in the heavens above. The study of observational astronomy and locating someone who has expertise in this field has become a rare find. The ancient civilizations had a keen interest in their skies and used the heavens as a navigational tool and as a form of entertainment associating mythology and stories about the constellations. Constellations were derived from mankind's attempt to bring order to the chaos of stars above them. They also realized the celestial objects of the night sky were beyond the control of mankind and associated the heavens with religion. Observational astronomy and familiarity with the night sky today is limited for the following reasons: • Many people live in cities and metropolitan areas have become so well illuminated that light pollution has become a real problem in observing the night sky. • Typical city lighting prevents one from seeing stars that are of fourth, fifth, sixth magnitude thus only a couple hundred stars will be seen. • Under dark skies this number may be as high as 2,500 stars and many of these dim stars helped form the patterns of the constellations. • Light pollution is accountable for reducing the appeal of the night sky and loss of interest by many young people as the night sky is seldom seen in its full splendor. • People spend less time outside than in the past, particularly at night. • Our culture has developed such a profusion of electronic devices that we find less time to do other endeavors in the great outdoors.

  • Globular Clusters, Though
    Appendix: What You’re Looking At Early astronomers divided astronomical objects into three main types: planets, stars, and what were called mists or clouds; in Latin, nebulae. Stars had fixed positions relative to one another, but the planets moved about, and so the ancient Greeks called them wanderers, plan¯et¯es. The changing positions of the planets were hard to explain, and none of the Solar System models proposed bytheancientGreeksorRomansadequatelyexplainedthingssuchasretrograde motion. But even though they didn’t understand why the planets moved about, the Greeks and Romans both placed huge value on interpreting the movements of the planets. This is the art of astrology, a practice that has developed independently in many different cultures around the world. That stars were in some way similar to the Sun was something the ancient Greeks had guessed at, but it wasn’t until the nineteenth century and the invention of spec- troscopy that scientists could demonstrate that the light produced by the Sun was the similar to that produced by the stars. Over time different types of stars were identi- fied, and it soon became clear that the Sun was a relatively small and ordinary star by cosmic standards, even though it is vitally important to us. Nebulae posed particular problems for astronomers prior to the invention of the telescope. To the naked eye all nebulae look alike, nothing more than faint, misty patches of light. Only with the telescope was the diversity of nebulae revealed, but while they could be seen to be morphologically different, astronomers of the early modern era didn’t understand that a planetary nebula is a very different thing to something like the Great Nebula in Andromeda, what we’d today recognize as a galaxy.

  • The First Cepheid. Information Access
    Sky & Telescope Oct 1997 v94 n4 p90(2) Page 1 The first cepheid. by Ken Crosswell Knowing the size, mass, energy, and age of any astronomical body depends totally on how well its distance is known, proof enough that distance is important to astronomers. To make calculations of distance, Cepheid variable stars, such as Delta Cephei and Eta Aquilae are used. © COPYRIGHT 1997 Sky Publishing Corporation presumed to be idiots and were treated accordingly. But Goodricke’s parents refused to accept this view and set The Cepheid variable stars, famous cosmic yardsticks, him on a vigorous academic course. He developed a really ought to be called the Aquilid variables. passion for science, especially astronomy. Finding distances is at the heart of astronomy. Most Pigott became Goodricke’s friend and mentor and taught physical characteristics of a star or galaxy, such as its him how to study the sky. Sometimes the two observed size, mass, age, and energy output, depend critically on together from Pigott’s well-equipped backyard observatory how well its distance is known. And distances are often three blocks from Goodricke’s home in York. Other times known poorly. they observed separately and compared notes.
