In one myth, Orion boasted he would kill all the wild animals on the earth. But, the earth goddess Gaia, who was the protector of all animals, produced a gigantic scorpion, whose body was so heavily encased that Orion was unable to pierce through the armour, and was himself stung to death. His companion Artemis was greatly saddened and arranged for Orion to be immortalised among the stars. Scorpius, the scorpion, was placed on the opposite side of the sky so that Orion would never be hurt by it again. To this day, Orion is never seen in the sky at the same time as Scorpius.

Dedicated to Hannelore Herbig c 2016 by Bo Reipurth Version 1.0 – April 19, 2016 Cover Image: The HH 24 complex in the Lynds 1630 cloud in Orion was discov- ered by Herbig and Kuhi in 1963. This near-infrared HST image shows several collimated Herbig-Haro jets emanating from an embedded multiple system of T Tauri stars. Courtesy Space Telescope Science Institute. 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.

  • Preliminary Analysis of Light Curves of Seven Carbon Stars J
    Contrib. Astron. Obs. Skalnat´ePleso 33, 119 { 133, (2003) Preliminary analysis of light curves of seven carbon stars J. Duˇsek1, Z. Mikul´aˇsek2 and J. Papouˇsek3 1 N. Copernicus Observatory and Planetarium in Brno, Krav´ıhora 2, 616 00 Brno, Czech Republic, (E-mail: [email protected]) 2 Institute of Theoretical Physics and Astrophysics, Faculty of Science, Masaryk University Brno, Kotl´aˇrsk´a2, 611 37 Brno, Czech Republic, (E-mail: [email protected]) 3 Ml´ynsk´a56, 602 00 Brno, Czech Republic Received: August 2, 2002 Abstract. We present a preliminary analysis of the light curves of the following carbon stars: WZ Cas, VY UMa, Y CVn, RY Dra, T Lyr, HK Lyr and TT Cyg, constructed on the basis of our own BV photoelectric observations obtained at the Brno Observatory in 1979-94 and Hipparcos observations. The analysis suggests that "semiregular" light curves of all studied stars can faithfully be expressed by a superposition of long-term changes and a set of medium-term harmonic variations (possibly pulsations) with periods from 50 to 500 days. Key words: AGB stars { carbon stars { individual stars { stellar pulsations { periods { UBV photometry { Hipparcos photometry 1. Introduction Chemically peculiar late stars, so-called "carbon stars", are asymptotic giant branch (AGB) objects whose atmospheres are vigorously polluted by chemical elements originating namely from carbon in nuclear processes in their deep in- teriors. Theoreticians claim that every star with the initial mass from 1.5 M to 4 M should go through the stage of a carbon star lasting about 3.105 years before it finally transforms into a white dwarf (Groenewegen et al., 1995).

    This page intentionally left blank NUCLEOSYNTHESIS AND CHEMICAL EVOLUTION OF GALAXIES Second Edition The distribution of elements in the cosmos is the result of many processes, and it provides a powerful tool to study the Big Bang, the density of baryonic matter, nucleosynthesis and the formation and evolution of stars and galaxies. This text- book, by a pioneer of the field, provides a lucid and wide-ranging introduction to the interdisciplinary subject of galactic chemical evolution for advanced under- graduates and graduate students. It is also an authoritative overview for researchers and professional scientists. In this textbook many exciting topics in astrophysics and cosmology are covered, from abundance measurements in astronomical sources, to light element produc- tion by cosmic rays and the effects of galactic processes on the evolution of the elements. Simple derivations for key results are provided, together with problems and helpful solution hints, enabling the student to develop an understanding of results from numerical models and real observations. This new edition includes results from recent space missions, including WMAP and FUSE, new material on abundances from stellar populations, nebular analysis and meteoric isotopic anomalies, and abundance analysis of X-ray gas, and several extra problems at the end of chapters.

This compilation is based upon earlier works of Mead et al. (1986), Pitts (1991) and our own. The IUE satellite has provided the scientific community with over 110,000 UV spectra which are now in the public domain. Prospective user of these IUE data are provided with a list that holds a total of 3776 IUE papers from the following journals: Journal Abbreviation Nr. Astronomical Journal AJ 200 Astronomy and Astrophysics A&A 982 Astronomy and Astrophysics Supplement A&AS 94 Astrophysical Journal APJ 1513 Astrophysical Journal Supplement APJS 112 Astrophysics and Space Science AP&SS 69 Advances in Space Research ASR 3 Geophysical Research Letters GRL 10 Irish Astronomical Journal IAJ 2 Icarus ICARUS 56 Journal of Geophysical Research JGR 19 Monthly Notices of the Royal Astr.

Dr. Franz Kerschbaum Ass.Prof. Dr. Josef Hron 2 Acknowledgments Doing a PhD is a school of Science, and of life. Hereafter I would like to thank all the people who made the accomplishment of this thesis possible in those years. First of all, I would like to express my deep gratitude to my supervisor Josef Hron, who, welcoming me in the AGB research group, gave me the possibility to grow so much professionally and personally. I learn a lot from you, thank you to be always available in explaining me the physics of the AGB stars and of interferometry, for our discussions, and for all the support and flexibility you gave me over the last year. I think that I gained a little bit of your trust, and this is very important to me! And of course thanks for sharing the passion for volleyball... and sweets! :) Thanks to my second supervisor Franz Kerschbaum, who has always been supportive and gave me very helpful inputs for my research.
