    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.

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.
  • Dhruva the Ancient Indian Pole Star: Fixity, Rotation and Movement

    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.

We report changes in shape and rapid and secular decreases in its nebular emission-line fluxes based on well calibrated images obtained by the Hubble Space Telescope in 1996, 2000, and 2016. Hen3-1357 is now a “recombination nebula”. Keywords: planetary nebulae: Planetary nebulae (1249), Post-asymptotic giant branch stars (2121), Ionization (2068) 1. Introduction Planetary nebulae (“PNe”) consist of stellar gas ejected in winds from the surfaces of post Asymptotic Branch Giant (“AGB”) stars. The winds systematically expose deeper and much hotter interior stellar layers until stellar energetic ultraviolet (“UV”) begins to ionize the ejected gas. The PN radiates a rich, luminous, and readily detectable set of emission lines (e.g., 6) as electron recombinations with H+ and He+ and optical forbidden lines of N+, O+, O++, S+, etc. These lines become increasingly visible by about a millennium after the winds begin as the central star shifts towards higher temperatures > 40 kK.

    About the Foroughi Cup and About the Seven Planets in the Ancient World

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).

COPYRIGHT BY THE MEDIAEVAL ACADEMY OF AMERICA '939 Printed in U. S. A. PUNTED BY THE WAVISLY FKES3, INC. BALTIMORE, MARYLAND PREFACE EDIAEVALISTS have long felt the need for an edition of the M only work of John the Scot which has hitherto remained un- published, his commentary on the De nuptiis Philologiae et Mercurii of Martianus Capella. I first became interested in this problem while a student at the Yale Graduate School. There, under the guidance of Professor E. T. Silk, I made a study of the ninth-century commentaries on the seven liberal arts with especial reference to John the Scot, and presented it, together with a critical edition of four books of his commen- tary, as a dissertation for the doctor's degree. Since then, I have com- pleted the text, and have incorporated, with some revision, the pertinent conclusions of the earlier study into the introduction to the present edi- tion. I have taken the opportunity to suggest a few of the interesting problems which a consideration of the commentary has brought to my attention, although my main purpose has always been simply to make available this important treatise. Constantly, during the course of my work, I have taken advantage of the knowledge and interest of Professor Silk.

    A Brief History of Beiji 北极 (Northern Culmen), with an Excursus on the Origin of the Character Di 帝”

    DRAFT OF WORK IN PROGRESS: NOT FOR CIRCULATION OR CITATION “A Brief History of Beiji 北极 (Northern Culmen), with an Excursus on the Origin of the Character di 帝” David W. Pankenier Lehigh University Abstract: In ancient Chinese astral lore, the imperial nomenclature associated with the circumpolar stars in the Palace of Purple Tenuity 紫微垣 points to the crucial importance of the north-pole in astrological, calendrical, and spiritual contexts. But preoccupation with this numinous region has a history dating back far earlier than the Qin and Han empires. This paper briefly surveys what is known about the pre-imperial history of the region of the ‘Northern Culmen,’ with particular reference to spiritual and metaphysical conceptions concerning the Northern Dipper, and to the void at the pivot of the heavens, where there was no prominent pole star throughout much of the formative period of classical Chinese civilization. The discussion concludes with a hypothesis about possible astral origins of the ancient form of the character used to denote the High God di 帝. Chinese preoccupation with astronomical orientation has a very long history. Archaeological evidence from the 5th millennium BCE Neolithic cultures of North China shows that burials and dwellings were already being oriented with particular attention to the diurnal and seasonal variations in the Sun’s position.1 With the beginning of the Bronze Age in the early 2nd millennium BCE and the inception of early state formation, such concepts had progressed to the point where ritually and politically important structures were uniformly quadrilateral in shape and cardinally oriented, with the longitudinal axis aligned with varying precision in a north-south direction.2 Palatial structures and royal tombs from the earliest dynastic states in the 2nd millennium BCE, that is, Xia,3 Shang, and Zhou, consistently display such orientation.

    Astronomers Observe Star Reborn in a Flash 13 September 2016

    Astronomers observe star reborn in a flash 13 September 2016 astronomers have observed an exception to this rule. "SAO 244567 is one of the rare examples of a star that allows us to witness stellar evolution in real time", explains Nicole Reindl from the University of Leicester, UK, lead author of the study. "Over only twenty years the star has doubled its temperature and it was possible to watch the star ionising its previously ejected envelope, which is now known as the Stingray Nebula." SAO 244567, 2700 light-years from Earth, is the central star of the Stingray Nebula and has been visibly evolving between observations made over the last 45 years. Between 1971 and 2002 the surface temperature of the star skyrocketed by almost 40 000 degrees Celsius. Now new observations made with the Cosmic Origins Spectrograph (COS) on the NASA/ESA Hubble Space Telescope have revealed that SAO 244567 has started to cool and expand. This image of the Stingray nebula, a planetary nebula This is unusual, though not unheard-of, and the 2400 light-years from Earth, was taken with the Wide rapid heating could easily be explained if one Field and Planetary Camera 2 (WFPC2) in 1998. In the assumed that SAO 244567 had an initial mass of 3 centre of the nebula the fast evolving star SAO 244567 to 4 times the mass of the Sun. However, the data is located. Observations made within the last 45 years show that SAO 244567 must have had an original showed that the surface temperature of the star mass similar to that of our Sun.
