Snake River Skies The Newsletter of the Magic Valley Astronomical Society www.mvastro.org Membership Meeting President’s Message Tim Frazier Saturday, April 14th 2018 April 2018 7:00pm at the Herrett Center for Arts & Science College of Southern Idaho. It really is beginning to feel like spring. The weather is more moderate and there will be, hopefully, clearer skies. (I write this with some trepidation as I don’t want to jinx Public Star Party Follows at the it in a manner similar to buying new equipment will ensure at least two weeks of Centennial Observatory cloudy weather.) Along with the season comes some great spring viewing. Leo is high overhead in the early evening with its compliment of galaxies as is Coma Club Officers Berenices and Virgo with that dense cluster of extragalactic objects. Tim Frazier, President One of my first forays into the Coma-Virgo cluster was in the early 1960’s with my [email protected] new 4 ¼ inch f/10 reflector and my first star chart, the epoch 1960 version of Norton’s Star Atlas. I figured from the maps I couldn’t miss seeing something since Robert Mayer, Vice President there were so many so closely packed. That became the real problem as they all [email protected] appeared as fuzzy spots and the maps were not detailed enough to distinguish one galaxy from another. I still have that atlas as it was a precious Christmas gift from Gary Leavitt, Secretary my grandparents but now I use better maps, larger scopes and GOTO to make sure [email protected] it is M84 or M86. -

Hutcheon Submitted in accordance with the requirements for the degree of Doctor of Philosophy. Research Institute: School of Environmental and Physical Sciences and Applied Mathematics. University of Keele June 2015 ii iii Abstract This thesis is in three parts: 1) a kinematical study of exoplanet host stars, 2) a study of the detached eclipsing binary V1094 Tau and 3) and observations of other eclipsing binaries. Part I investigates kinematical biases between two methods of detecting exoplanets; the ground based transit and radial velocity methods. Distances of the host stars from each method lie in almost non-overlapping groups. Samples of host stars from each group are selected. They are compared by means of matching comparison samples of stars not known to have exoplanets. The detection methods are found to introduce a negligible bias into the metallicities of the host stars but the ground based transit method introduces a median age bias of about -2 Gyr. -

Double and Multiple Star Measurements in the Northern Sky with a 10” Newtonian and a Fast CCD Camera in 2006 Through 2009
Vol. 6 No. 3 July 1, 2010 Journal of Double Star Observations Page 180 Double and Multiple Star Measurements in the Northern Sky with a 10” Newtonian and a Fast CCD Camera in 2006 through 2009 Rainer Anton Altenholz/Kiel, Germany e-mail: rainer.anton”at”ki.comcity.de Abstract: Using a 10” Newtonian and a fast CCD camera, recordings of double and multiple stars were made at high frame rates with a notebook computer. From superpositions of “lucky images”, measurements of 139 systems were obtained and compared with literature data. B/w and color images of some noteworthy systems are also presented. mented double stars, as will be described in the next Introduction section. Generally, I used a red filter to cope with By using the technique of “lucky imaging”, seeing chromatic aberration of the Barlow lens, as well as to effects can strongly be reduced, and not only the reso- reduce the atmospheric spectrum. For systems with lution of a given telescope can be pushed to its limits, pronounced color contrast, I also made recordings but also the accuracy of position measurements can be with near-IR, green and blue filters in order to pro- better than this by about one order of magnitude.

Korotangi (The Dove)
Korotangi (The Dove) The legend of the korotangi is that it came in the Tainui waka as one of the heirlooms which had been blessed by the high priests in Hawaiiki and which in the new country, would ensure good hunting for the tribe. It was said that the Kawhia and Waikato tribes, who descended from Tainui stock, took the korotangi into battle with them, setting it up on a hill and consulting it as an oracle. The "korotangi" can mean "to roar and rush as the sound of water" in either Maori, Hawaiian or Samoan has been used to support the legend that it was bought on the Tainui waka from afar. The expression “Korotangi” is still used as a term of endearment, or as a simile for any object treasured or loved. A mother lamenting the death of a child will, in her lament, refer to her lost one as her “Korotangi.” 1 No doubt the simile has its origin in the above tradition, which also seems to be a fea- sible explanation of the waiata. It certainly explains the reference to the eat- ing of the pohata leaves and the huahua from Rotorua, as well as the allu- sion to the taumata (hill-top or ridge). The Korotangi, Tawhio Throne, and the art work depicting The Lost Child TeManawa and Korotangi, arrived at Turangawaewae Marae on the same day. The Heart of Heaven is in part the sharing of the walk of TeManawa who lives these things, has fulfilled prophesy. Her journey has been documented since 1992 to current. -
The Survey of Western Palestine. a General Index

AND TO THE ARABIC AND ENGLISH NAME LISTS. COMPILED BY HENRY C. STEWARDSON. 1888 Electronic Edition by Todd Bolen BiblePlaces.com 2005 PREFACE. ITTLE explanation is required of the arrangement followed in this Volume, beyond calling L attention to the division of this Volume into two parts: the first forms a combined Index to the three Volumes of the Memoirs, the Special Papers, the Jerusalem Volume, the Flora and Fauna of Palestine, and the Geological Survey; and the second is an Index to the Arabic and English Name Lists. This division was considered advisable in order to avoid the continual use of reference letters to the Name Lists, which would otherwise have been required. The large number of entries rendered it absolutely necessary to make them as brief as possible; but it is hoped that it will be found that perspicuity has not been sacrificed to brevity. A full explanation of the reference letters used will be found on the first page. The short Hebrew Index at the end of the Volume has been kindly furnished by Dr. W. Aldis Wright. H. C. S. PREFACE TO ELECTRONIC EDITION. ore than a hundred years after the publication of the Survey of Western Palestine, its M continued value is well-known and is evidenced by the recent reprint and librarians’ propensity to store the work in restricted areas of the library. -

Statistics and Supermetallicity: the Metallicity of Mu Leonis
A&A 379, 917–923 (2001) Astronomy DOI: 10.1051/0004-6361:20011380 & c ESO 2001 Astrophysics Statistics and supermetallicity: The metallicity of Mu Leonis B. J. Taylor? Department of Physics and Astronomy, N283 ESC, Brigham Young University, Provo, UT 84602-4360, USA Received 9 February 2001 / Accepted 2 October 2001 Abstract. For the often-studied “SMR” giant µ Leo, Smith & Ruck (2000) have recently found that [Fe/H] ∼ +0.3 dex. Their conclusion is tested here in a “statistical” paradigm, in which statistical principles are used to select published high-dispersion µ Leo data and assign error bars to them. When data from Smith & Ruck and from Takeda et al. (1998) are added to a data base compiled in 1999, it is found that conclusions from an earlier analysis (Taylor 1999c) are essentially unchanged: the mean value of [Fe/H] ∼ +0.23 0.025 dex, and values ≤+0.2 dex are not clearly ruled out at 95% confidence. In addition, the hypothesis that [Fe/H] ≥ +0.3dexwhich emerges from the Smith-Ruck analysis is formally rejected at 98% confidence. The “default paradigm” which is commonly used to assess µ Leo data is also considered. The basic characteristics of that paradigm continue to be a) unexplained exclusion of statistical analysis, b) inadequately explained deletions from an [Fe/H] data base containing accordant data, and c) an undefended convention that µ Leo is to have a metallicity of about +0.3dex or higher. As a result, it seems fair to describe the Smith-Ruck application and other applications of the default paradigm as invalid methods of inference from the data.
