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. DSO’s ● ***M42 “Orion Nebula” (Neb) with Trapezium A stellar nursery where new stars are being born, perhaps a thousand stars. These are immense clouds of interstellar gas and dust collapse inward to form stars, mainly of ionized hydrogen which gives off the red glow so dominant, and also ionized greenish oxygen gas. The youngest stars may be less than 300,000 years old, even as young as 10,000 years old (compared to the Sun, 4.6 billion years old). 1300 ly. 1 ● *M43--(Neb) “De Marin’s Nebula” The star-forming “comma-shaped” region connected to the Orion Nebula. ● *M78--(Neb) Hard to see.

Determination of Stellar Parameters for M-Dwarf Stars: the NIR Approach
Determination of stellar parameters for M-dwarf stars: the NIR approach by Daniel Thaagaard Andreasen A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Graduate Department of Departamento de Fisica e Astronomia University of Porto c Copyright 2017 by Daniel Thaagaard Andreasen Dedication To Linnea, Henriette, Rico, and Else For always supporting me ii Acknowledgements When doing a PhD it is important to remember it is more a team effort than the work of an individual. This is something I learned quickly during the last four years. Therefore there are several people I would like to thank. First and most importantly are my two supervisors, Sérgio and Nuno. They were after me in the beginning of my studies because I was too shy to ask for help; something that I quickly learned I needed to do. They always had their door open for me and all my small questions. It goes without saying that I am thankful for all their guidance during my studies. However, what I am most thankful for is the freedom I have had to explorer paths and ideas on my own, and with them safely on the sideline. This sometimes led to failures and dead ends, but it make me grow as a researcher both by learning from my mistake, but also by prioritising my time. When I thank Sérgio and Nuno, my official supervisors, I also have to thank Elisa. She has been my third unofficial supervisor almost from the first day. Although she did not have any experience with NIR spectroscopy, she was never afraid of giving her opinion and trying to help. -

Astronomy of the Northern Sky— - a Sky Quest on Star Lives - Larry Krumenaker
Astronomy of the Northern Sky— - A Sky Quest on Star Lives - Larry Krumenaker There is no topic so vital to an astronomy course as the life of a star like our Sun. It ties in to so many questions: How old is our planet? Where do we come from? What is the future of the solar sys- tem? Why do all the stars look different in brightness and/or color? We have looked at parts of this story in issues past, in this column and in some other TCA articles. Here we begin to put all the previous col- umns of information together into the full story of what we are, where we came from, where we are, and where are we going. This is going to be somewhat like a Sky Quest, a search for objects in the northern sky (see Figure 1), instead of a Web Quest, with the story and sky info (the latter in this blue color) moving along together. Non-stellar objects are labeled with catalog abbreviations and numbers: M=Messier’s Catalog, NGC is the New General Catalog, and IC means Index Catalog, a follow-up to the NGC. We’ve covered star names and spectral classes in earlier TCA issues, except for HD, the Henry Draper catalog. In this Sky Quest, we shall talk about stellar evolution, the birth, life and death of a star like our Sun, and finding the representative stages up in the northern sky. Figure 2. The stages in the life cycle of the Sun. Our Past The basics of stellar evolution are the universe is the ultimate in recycling. -

Lists and Charts of Autostar Named Stars
APPENDIX A Lists and Charts of Autostar Named Stars Table A.I provides a list of named stars that are stored in the Autostar database. Following the list, there are constellation charts which show where the stars are located. The names are in alphabetical orderalong with their Latin designation (see Appendix B for complete list ofconstellations). Names in brackets 0 in the table denote a different spelling to one that is known in the list. The star's co-ordinates are set to the same as accuracy as the Autostar co-ordinates i.e. the RA or Dec 'sec' values are omitted.
