GEORGE HERBIG and Early Stellar Evolution
GEORGE HERBIG and Early Stellar Evolution Bo Reipurth Institute for Astronomy Special Publications No. 1 George Herbig in 1960 —————————————————————– GEORGE HERBIG and Early Stellar Evolution —————————————————————– Bo Reipurth Institute for Astronomy University of Hawaii at Manoa 640 North Aohoku Place Hilo, HI 96720 USA . 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. -

The nearest stars provide a fundamental constraint for our understanding of stellar physics and the Galaxy. The nearby sample serves as an anchor where all objects can be seen and understood with precise data. This work is triggered by the most recent data release of the astrometric space mission Gaia and uses its unprecedented high precision parallax measurements to review the census of objects within 10 pc. Aims. The first aim of this work was to compile all stars and brown dwarfs within 10 pc observable by Gaia and compare it with the Gaia Catalogue of Nearby Stars as a quality assurance test. We complement the list to get a full 10 pc census, including bright stars, brown dwarfs, and exoplanets. -

The COLOUR of CREATION Observing and Astrophotography Targets “At a Glance” Guide
The COLOUR of CREATION observing and astrophotography targets “at a glance” guide. (Naked eye, binoculars, small and “monster” scopes) Dear fellow amateur astronomer. Please note - this is a work in progress – compiled from several sources - and undoubtedly WILL contain inaccuracies. It would therefor be HIGHLY appreciated if readers would be so kind as to forward ANY corrections and/ or additions (as the document is still obviously incomplete) to: [email protected]. The document will be updated/ revised/ expanded* on a regular basis, replacing the existing document on the ASSA Pretoria website, as well as on the website: coloursofcreation.co.za . This is by no means intended to be a complete nor an exhaustive listing, but rather an “at a glance guide” (2nd column), that will hopefully assist in choosing or eliminating certain objects in a specific constellation for further research, to determine suitability for observation or astrophotography. There is NO copy right - download at will. Warm regards.

A Compilation of Relevant Articles from MMM’s first 25 years, issues 1-250 Introduction: Every atom in our bodies, except hydrogen, has been forged in the fusion furnaces in the cores of stars long since exploded, peppering the interstellar gas clouds with them - clouds out of which future stars and their planets eventually formed. To recast a biblical phrase, “Of stardust thou art, and to the stars thou shalt return!” Humankind was born in Africa, and for well over a hundred thousand years has been spreading from one continent to another, becoming an “intercontinental” species. Now we are crossing another kind of sea to another kind of continent, The Moon, then to others beyond, our next goal is to become an “interplanetary” species. Whether we spread beyond our native solar system depends on many things, surviving our pre- sent and coming geopolitical, global financial, and environmental-economic crises just as important as leaping technological hurdles. But the call is there, and we feel it whenever we look up at the star- studded heavens on a clear night. Moon Miners’ Manifesto’s purpose has been to help flush out, and then flesh out how we will establish a growing civilian beachhead on the Moon, Mars and beyond. Here and there, we’ve had a few articles peeping beyond our solar system, about what might lay beyond along our path “home.” They are reprinted below. Our near-term goal is to learn much more about what lies out there, by telescopes on the Moon and in space INDEX MMM THEMES: Starbound! ARTICLES: MMM #17 Design for an Amateur Lunar -

The activities are grouped into several major areas of study in astronomy: lunar phases and eclipses, the Sun and the seasons, the planets, the scale of the solar system, comets and meteors, star-finding and constellations, stars, galaxies and the universe, space exploration and the Search for Extra-Terrestrial Intelligence (SETT), tools of the astronomer, debunking pseudoscience, and astronomy in different cultures. An extensive glossary and a section that provides interdisciplinary teaching ideas are included.
