Preface This volume contains the extended abstracts of the contributed papers given at the SummerSchool on Interstellar Processes which took place on July 3-7, 1986 in Grand Teton National Park, Wyoming. A separate publication from D. Reidel contains the invited papers given at this meeting; the program of these invited papers appears on the following two pages. The purpose of the SummerSchool on Interstellar Processes was to present a summaryof the current understanding of the interstellar mediumand to discuss the basic physical processes which underlie interstellar phenomena. Wewere especially interested to attract an audience of graduate students and younger astronomers and to expose themto the wide variety of interesting processes operating in the interstellar medium. Although the invited talks were explicitly meant to be pedagogical reviews in line with the "summerschool" tone of this meeting, the contributed papers in this volume are appropriate to typical symposia: they are generally reports on current research activities. Approximately 200 astronomers attended the summerschool and most of them appear as authors on one of the contributed papers in this volume. Wewould like to acknowledge their contributions, as well as the work of the Scientific Organizing Committee (J.M. Shu]l, L. Rodriguez, P. Martin, N. Scoville, C. Lada, D. Flower, T. de Jong, and J. Hackwe]l). Weare also very grateful to the Local Organizing Committee(P. Johnson, M. Greenhouse,and T. Hayward), especially for attending to all the details which madethe stay at Jackson Lake Lodge so enjoyable for the participants and their families. Finally, we would like to thank the Departmentof Physics and Astronomy, the Dean's Office of the College of Arts and Sciences, and the Research Office of the University of Wyomingfor the financial support which, to a large degree, enabled many graduate students to attend the meeting.

  • A Search for Pulsations in Helium White Dwarfs
    DRAFT VERSION OCTOBER 13, 2018 Preprint typeset using LATEX style emulateapj v. 11/10/09 A SEARCH FOR PULSATIONS IN HELIUM WHITE DWARFS JUSTIN D. R. STEINFADT1,LARS BILDSTEN1,2,DAVID L. KAPLAN3,BENJAMIN J. FULTON4,STEVE B. HOWELL5, T. R. MARSH6 , ERAN O. OFEK7,8 , AND AVI SHPORER1,4 Draft version October 13, 2018 ABSTRACT The recent plethora of sky surveys, especially the Sloan Digital Sky Survey, have discovered many low- mass (M < 0.45M⊙) white dwarfs that should have cores made of nearly pure helium. These WDs come in two varieties; those with masses 0.2 < M < 0.45M⊙ and H envelopes so thin that they rapidly cool, and those with M < 0.2M⊙ (often called extremely low mass, ELM, WDs) that have thick enough H envelopes to sustain 109 years of H burning. In both cases, these WDs evolve through the ZZ Ceti instability strip, Teff ≈ 9,000–12,000K, where g-mode pulsations always occur in Carbon/Oxygen WDs. This expectation, plus theoretical work on the contrasts between C/O and He core WDs, motivated our search for pulsations in 12 well characterized helium WDs. We report here on our failure to find any pulsators amongst our sample. Though we have varying amplitude limits, it appears likely that the theoretical expectations regarding the onset of pulsations in these objects requires closer consideration. We close by encouraging additional observations as new He WD samples become available, and speculate on where theoretical work may be needed. Subject headings: stars: white dwarfs— stars: oscillations 1. INTRODUCTION for C/O-core WDs.

  • Frankfurt Pleiades Star Map 2
    FRANKFURT PLEIADES STAR MAP 2 In investigating the Martian connection of the Pleiadian pattern of Frankfurt, one cannot avoid to address the origins at least in the propagation of this motif in the modern era and in all the financial powerhouses of today’s World Financial Oder. This is in part the Pleiades conspiracy as this modern version of the ‘Pleiadian Conspiracy’ started here in Frankfurt with the Rothschild dynasty by Amschel Moses Bauer, 1743. This critique is not meant to placate all those of the said family or those that work in such financial structures or businesses and specifically not those in Frankfurt. However the argument is that those behind the family apparatus are of a cabal that is connected to the allegiance of not the true GOD of the Universe, YHVH but to the false usurper Lucifer. It is Lucifer they worship and venerate as the ‘god of this world’ and is the God of Mammon according to Jesus’ assessment. According to research and especially based on The 13 Bloodlines of the Illuminati by Springmeier, the current financial domination of the world began in Frankfurt with Mayer Amschel. They were of Jewish extract but adhere more toward the Kabbalistic, Zohar, and ancient Babylonian secret mystery religion initiated by Nimrod after the Flood of Noah. The star Taygete corresponds to the Literaturahaus building. T he star Celaena corresponds to the Burgenamt Zentrales building. The star Merope corresponds to the area of the Timmitus und THE PLEIADES Hyperakusis Center. The star Alcyone corresponds to the Oper FINANCIAL DISTRICT The Bearing-Point building is Frankfurt or the Opera House.

  • A Review on Substellar Objects Below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs Or What?
    geosciences Review A Review on Substellar Objects below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs or What? José A. Caballero Centro de Astrobiología (CSIC-INTA), ESAC, Camino Bajo del Castillo s/n, E-28692 Villanueva de la Cañada, Madrid, Spain; [email protected] Received: 23 August 2018; Accepted: 10 September 2018; Published: 28 September 2018 Abstract: “Free-floating, non-deuterium-burning, substellar objects” are isolated bodies of a few Jupiter masses found in very young open clusters and associations, nearby young moving groups, and in the immediate vicinity of the Sun. They are neither brown dwarfs nor planets. In this paper, their nomenclature, history of discovery, sites of detection, formation mechanisms, and future directions of research are reviewed. Most free-floating, non-deuterium-burning, substellar objects share the same formation mechanism as low-mass stars and brown dwarfs, but there are still a few caveats, such as the value of the opacity mass limit, the minimum mass at which an isolated body can form via turbulent fragmentation from a cloud. The least massive free-floating substellar objects found to date have masses of about 0.004 Msol, but current and future surveys should aim at breaking this record. For that, we may need LSST, Euclid and WFIRST. Keywords: planetary systems; stars: brown dwarfs; stars: low mass; galaxy: solar neighborhood; galaxy: open clusters and associations 1. Introduction I can’t answer why (I’m not a gangstar) But I can tell you how (I’m not a flam star) We were born upside-down (I’m a star’s star) Born the wrong way ’round (I’m not a white star) I’m a blackstar, I’m not a gangstar I’m a blackstar, I’m a blackstar I’m not a pornstar, I’m not a wandering star I’m a blackstar, I’m a blackstar Blackstar, F (2016), David Bowie The tenth star of George van Biesbroeck’s catalogue of high, common, proper motion companions, vB 10, was from the end of the Second World War to the early 1980s, and had an entry on the least massive star known [1–3].

  • Stars and Their Spectra: an Introduction to the Spectral Sequence Second Edition James B
    Cambridge University Press 978-0-521-89954-3 - Stars and Their Spectra: An Introduction to the Spectral Sequence Second Edition James B. Kaler Index More information Star index Stars are arranged by the Latin genitive of their constellation of residence, with other star names interspersed alphabetically. Within a constellation, Bayer Greek letters are given first, followed by Roman letters, Flamsteed numbers, variable stars arranged in traditional order (see Section 1.11), and then other names that take on genitive form. Stellar spectra are indicated by an asterisk. The best-known proper names have priority over their Greek-letter names. Spectra of the Sun and of nebulae are included as well.

  • The Egg Nebula 15 April 2019
    Image: the Egg Nebula 15 April 2019 Eventually the star stops shedding material and the core remnant heats up, exciting the expelled gas so that it glows brightly and becomes a planetary nebula. The dark band, sweeping beams, and criss- crossing arcs in this image can reveal a lot about the complex environment of a dying star. The central band is a cocoon of dust hiding the star from view. Beams of light emanate from the obscured star, and it is thought that they are due to starlight escaping from the ring-shaped holes in the dusty cocoon that surrounds the star. The holes are possibly carved by a high-speed stream of matter, although the cause of these jets are unknown. The Credit: Raghvendra Sahai and John Trauger (JPL), the spoke-like features are shadows cast by blobs of WFPC2 science team, and NASA/ESA material within the region of the holes in the cocoon. Numerous bright arcs intersect the beams: these The Egg Nebula is a preplanetary nebula, created are shells of matter ejected by the star. The arcs by a dying star in the process of becoming a are like tree rings, and can tell us something about planetary nebula. Planetary nebulas have nothing the object's age as they reveal that the rate of mass to do with planets – the name arose when 18th ejection has varied between 100 and 500 years century astronomers spotted them in their throughout its 10 000 year history.
