July 2017 FORT WORTH ASTRONOMICAL SOCIETY PAGE 3 Young Astronomers Light pollution is so important I wanted to publish more on it. Light pollution is excessive and inappropriate artificial light. The four components of light pollution are often combined and may overlap: • Urban Sky Glow—the brightening of the night sky over inhabited areas. • Light Trespass—light falling where it is not in- tended, wanted, or needed. • Glare—excessive brightness which causes visual discomfort. High levels of glare can decrease visi- bility. • Clutter—bright, confusing, and excessive group- ings of light sources, commonly found in over-lit e urban areas. The proliferation of clutter contrib- utes to urban sky glow, trespass, and glare. We need to educate our neighbors on it.

  • The Summer Sky by Dr
    The Summer Sky by Dr. Whitney Shane, MIRA’s Charles Hitchcock Adams Fellow Fixed Stars Some years ago this column had occasion to discuss planetary nebulae, using the Ring Nebula in Lyra, everyone’s favorite, as an example. The simple morphology of the Ring Nebula makes it ideal for this purpose. It can be explained as a slightly ellipsoidal expanding shell, where the asym- metry is due to a slight anisotropy in the initial expansion velocity. Very few planetary nebulae have the simple structure of the Ring Nebula. In fact, there is a baffling variety in the shapes of these objects. Most of them, however, show symmetry about a plane, which we might identify with the equator of the central star. The expansion seems to take place mainly in the direction of the poles. This could be caused by the presence of a massive ring of material around the equator, which would direct the expansion toward the poles. This ring might have been left over from the giant phase of the star. This agreeable situa- tion came to an abrupt end when Hubble Space Telescope images of planetary nebulae, starting with the Cat’s Eye Nebula (NGC 6543), showed far more com- plex structures than had been previously sus- pected. This complexity, particularly its fine detail, could not be ex- plained by the model of an equatorial ring direct- ing a general expansion toward the poles. Attempts to explain these structures seem to fall into two categories. The presence of a companion star would provide both the dy- namical perturbations and the symmetry plane (in this case the orbital plane) required by the observa- tions.

  • THUBAN the Star Thuban in the Constellation Draco (The Dragon) Was the North Pole Star Some 5,000 Years Ago, When the Egyptians Were Building the Pyramids
    STAR OF THE WEEK: THUBAN The star Thuban in the constellation Draco (the Dragon) was the North Pole Star some 5,000 years ago, when the Egyptians were building the pyramids. Thuban is not a particularly bright star. At magnitude 3.7 and known as alpha draconis it is not even the brightest star in its constellation. What is Thuban’s connection with the pyramids of Egypt? Among the many mysteries surrounding Egypt’s pyramids are the so-called “air shafts” in the Great Pyramid of Giza. These narrow passageways were once thought to serve for ventilation as the The Great Pyramid of Giza, an enduring monument of ancient pyramids were being built. In the 1960s, though, Egypt. Egyptologists believe that it was built as a tomb for fourth dynasty Egyptian Pharaoh Khufu around 2560 BC the air shafts were recognized as being aligned with stars or areas of sky as the sky appeared for the pyramids’ builders 5,000 years ago. To this day, the purpose of all these passageways inside the Great Pyramid isn’t clear, although some might have been connected to rituals associated with the king’s ascension to the heavens. Whatever their purpose, the Great Pyramid of Giza reveals that its builders knew the starry skies intimately. They surely knew Thuban was their Pole Star, the point around which the heavens appeared to turn. Various sources claim that Thuban almost exactly pinpointed the position of the north celestial pole in the This diagram shows the so-called air shafts in the Great year 2787 B.C.

  • New Atmospheric Parameters and Spectral Interpolator for the MILES Cool Stars Kaushal Sharma1,2,3, Philippe Prugniel1,2, and Harinder P

The full spectrum fitting of stellar spectra against a library of empirical spectra is a well-established approach to measure the atmospheric parameters of FGK stars with a high internal consistency. Extending it towards cooler stars still remains a challenge. Aims. We address this question by improving the interpolator of the Medium-resolution INT Library of Empirical Spectra (MILES) library in the low effective temperature regime (Teff < 4800 K), and we refine the determination of the parameters of the cool MILES stars. Methods. We use the ULySS package to determine the atmospheric parameters (Teff,logg and [Fe/H]), and measure the biases of the results with respect to our updated compilation of parameters calibrated against theoretical spectra. After correcting some systematic effects, we compute a new interpolator that we finally use to redetermine the atmospheric parameters homogeneously and assess the biases. Results. Based on an updated literature compilation, we determine Teff in a more accurate and unbiased manner compared to those determined with the original interpolator.

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.

  • Dhruva the Ancient Indian Pole Star: Fixity, Rotation and Movement
    Indian Journal of History of Science, 46.1 (2011) 23-39 DHRUVA THE ANCIENT INDIAN POLE STAR: FIXITY, ROTATION AND MOVEMENT R N IYENGAR* (Received 1 February 2010; revised 24 January 2011) Ancient historical layers of Hindu astronomy are explored in this paper with the help of the Purân.as and the Vedic texts. It is found that Dhruva as described in the Brahmân.d.a and the Vis.n.u purân.a was a star located at the tail of a celestial animal figure known as the Úiúumâra or the Dolphin. This constellation, which can be easily recognized as the modern Draco, is described vividly and accurately in the ancient texts. The body parts of the animal figure are made of fourteen stars, the last four of which including Dhruva on the tail are said to never set. The Taittirîya Âran.yaka text of the Kr.s.n.a-yajurveda school which is more ancient than the above Purân.as describes this constellation by the same name and lists fourteen stars the last among them being named Abhaya, equated with Dhruva, at the tail end of the figure. The accented Vedic text Ekâgni-kân.d.a of the same school recommends observation of Dhruva the fixed Pole Star during marriages. The above Vedic texts are more ancient than the Gr.hya-sûtra literature which was the basis for indologists to deny the existence of a fixed North Star during the Vedic period. However the various Purân.ic and Vedic textual evidence studied here for the first time, leads to the conclusion that in India for the Yajurvedic people Thuban (α-Draconis) was Dhruva the Pole Star c 2800 BC.

  • About the Foroughi Cup and About the Seven Planets in the Ancient World
    Archaeoastronomy and Ancient Technologies 2018, 6(2), 31–37; http://aaatec.org/art/a_cm2 www.aaatec.org ISSN 2310-2144 About the Foroughi Cup and about the seven planets in the Ancient World Mario Codebò 1, Henry De Santis 2 1 Archeoastronomia Ligustica, S.I.A., SAIt, Genoa, Italy; E-Mail: [email protected] 2 Archeoastronomia Ligustica, S.I.A., SAIt, Genoa, Italy; E-Mail: [email protected] Abstract The Foroughi Cup is an artefact of the 8th century BC of Aramaic cultural context, inside which images of stars and constellations are reproduced. In this study of ours we start from the conclusions reached by Amadasi Guzzo and Castellani in their two works of 2005 and 2006 and we add some further considerations and identifications. We then explain the hypothesis that some cultures of the Ancient World include seven planets, excluding the Moon and the Sun, because Mercury and Venus, always visible only at dawn or at sunset, were perhaps considered four different planets. Finally, we propose the thesis that their evil character depends, as for every new star (novae, supernovae, comets, etc.), on the fact that they alter the synchrony of the cosmos with their variable motion (variable declination heaven bodies). Keywords: Foroughi Cup, planets, Moon, Sun, Aramaic culture. The Foroughi Cup The Foroughi Cup is a bronze artefact (fig. 1), dated to the first half of the 1st millennium BC, containing in its concave interior a representation of the celestial vault and seven very small Aramaic inscriptions, only three of which are quite legible: ŠMŠ = Sun (above the representation of the Sun, in which a lion's head is also engraved); ŠHR = Moon (above the representation of the crescent of the Moon); hypothetically R'Š ŠR' = Head of the Bull (above the bucranium).

  • El Dragon De Gaudi En Barcelona
    NETWORK FOR ASTRONOMY SCHOOL EDUCATION EL DRAGON DE GAUDI EN BARCELONA Rosa M. Ros – NASE Introducción En 1884 Gaudí proyecta los pabellones de entrada y los jardines de la finca que tiene Eusebi Güell Bacigalupi en la zona de Pedralbes en Barcelona como un homenaje póstumo al suegro del Sr. Güell que pasaba temporadas en dicha finca. El martes 16 de enero de 1883 falleció en Barcelona el primer Marqués de Comillas, Antonio López López y los Pabellones Güell se realizan del 1884 al 1887. Para ello Gaudí se inspira en el Jardín de las Hespérides tal y como Jacinto Verdaguer lo describía en su poema La Atlántida. Verdaguer dedicó este poema en 1877 al Marqués de Comillas, y curiosamente el autor lo termino de escribir en esta misma finca. La finca Güell El conjunto se compone de la casa de los guardias y las caballerizas. Dos casas unidas por una puerta monumental (figura 1). En la entrada destaca la gran escultura de hierro forjado de Ladón, el dragón mitológico adversario de Hércules en su undécimo trabajo. Después de la muerte de Eusebio Güell, en 1918, sus descendientes ceden la casa y parte de los terrenos de la finca para construcción del Palacio Real de Pedralbes. Las antiguas caballerizas, el picador y la casa del guardia forman parte actualmente de la Universidad de Barcelona. Las caballerizas son la sede actual de la Real Cátedra Gaudí de la Universidad Politécnica de Cataluña. Figura 1: Pabellones de la Finca Güell: Casa del Guardia, puerta y Caballerizas.
