HORNE Preface Preface We welcome the American Association of Variable Star Observers (AAVSO) to the 31st annual SAS Sympo- sium on Telescope Science. The first joint meeting between the Societry for Astronomical Sciences and the AAVSO, held in 2009, was a tremendous success, bringing in presenters from around the world and in record numbers. Current plans are for the AAVSO to make this a biannual affair, merging its annual Spring meeting in even-numbered years with the SAS Symposium. The SAS Board of Directors is looking forward to a long and rewarding partnership that brings together some of the world’s best backyard and professional astronomers to share their experiences and expertise in the name of promoting astronomical research to advance our knowledge of the Universe. Not everyone wants to give a presentation but they still want to contribute to the Symposium by submitting a paper for the proceedings. So, this year, partly because of the unprecedented number of papers received, the proceedings include a section not just for poster papers but “papers without presentation.” We may try to do this in future years as well but, as always, our first goal is to get presenters who also submit papers. The live presen- tations are vital for spurring discussion both during Q&A and in groups outside the formal paper sessions. It takes many people to have a successful conference, starting with the Conference Committee. This year the regular committee members are: Lee Snyder Robert D. Stephens Robert Gill Jerry L. Foote Cindy Foote Margaret Miller Brian D. Warner Robert K. Buchheim Dale Mais There are many others involved in a successful conference. The editors take time to note the many volunteers who put in considerable time and resources. We also thank the staff and management of the Northwoods Resort in Big Bear Lake, CA, for their efforts at accommodating the Society and our activities. Membership dues alone do not fully cover the costs of the Society and annual conference. We owe a great debt of gratitude to our corporate sponsors: Sky and Telescope, Software Bisque, Santa Barbara Instruments Group, PlaneWave Instruments, Apogee Instruments, Inc., and DC-3 Dreams. Thank you! Finally, there would be no conference without our speakers and poster presenters and those sitting attentively in the audience (you’re not doing your email right now, are you?). We thank them for making this one of the pre- miere pro-am events in the world. Brian D. Warner Robert K. Buchheim Jerry L.

Photometry of Hubble’s First Cepheid in the Andromeda Galaxy, M31 Bill Goff AAVSO 13508 Monitor Lane Sutter Creek, CA 95685 [email protected] Matt Templeton AAVSO 49 Bay State Rd. Cambridge, MA 02138, USA [email protected] Richard Sabo AAVSO [email protected] Tim Crawford AAVSO [email protected] Michael Cook AAVSO [email protected] Abstract In the 1920s Hubble discovered a variable star in the Andromeda Galaxy, M31 which later was revealed to be a Cepheid type variable. Hubble’s observations confirmed that M31 was indeed at remote star system separate from our own Milky Way. We present here recent photometry of this object made during 2010 and 2011. These observations were made by members of the AAVSO at the request of the Space Telescope Science Institute’s Heritage Project. Over 300 Rc, V and unfiltered observations have been made. These are the first observations in current times to establish a period for the object. The period of this Cepheid as measured here is in agreement with the earlier data from 1920s and 1950s.

Today, nearly 70% by weight of the diamonds polished worldwide come from India. The feature article in this issue discuss- es India’s near-monopoly of the cut diamond industry, and reviews India’s impact on the worldwide diamond trade. The availability of an enormous amount of small, low-cost pg. 42 Indian diamonds has recently spawned a growing jewelry manufacturing sector in India. However, the Indian diamond jewelery–making tradition has been around much longer, pg. 46 as shown by the 19th century necklace (39.0 cm long), pendant (4.5 cm high), and bracelet (17.5 cm long) on the cover.

EVIDENCE FOR VERY EXTENDED GASEOUS LAYERS AROUND O-RICH MIRA VARIABLES AND M GIANTS B. Mennesson,1 G. Perrin,2 G. Chagnon,2 V. Coude du Foresto,2 S. Ridgway,3 A. Merand,2 P. Salome,2 P. Borde,2 W. Cotton,4 S. Morel,5 P. Kervella,5 W. Traub,6 and M. Lacasse6 Received 2002 March 15; accepted 2002 July 3 ABSTRACT Nine bright O-rich Mira stars and five semiregular variable cool M giants have been observed with the Infrared and Optical Telescope Array (IOTA) interferometer in both K0 (2.15 lm) and L0 (3.8 lm) broad- band filters, in most cases at very close variability phases. All of the sample Mira stars and four of the semire- gular M giants show strong increases, from ’20% to ’100%, in measured uniform-disk (UD) diameters between the K0 and L0 bands. (A selection of hotter M stars does not show such a large increase.) There is no evidence that K0 and L0 broadband visibility measurements should be dominated by strong molecular bands, and cool expanding dust shells already detected around some of these objects are also found to be poor candi- dates for producing these large apparent diameter increases. Therefore, we propose that this must be a con- tinuum or pseudocontinuum opacity effect. Such an apparent enlargement can be reproduced using a simple two-component model consisting of a warm (1500–2000 K), extended (up to ’3 stellar radii), optically thin ( ’ 0:5) layer located above the classical photosphere.

  • Naretha Meteorite (Synonyms Kingoonya, Kingooya)
    Rec. West. Aust. Mus., 1976, 4 (1) NARETHA METEORITE (Sync;>nyms: Kingoonya, Kingooya) W.H. CLEVERLY* [Received 27 May 1975. Accepted 1 October 1975. Published 31 August 1976.1 ABSTRACT Much of the missing portion of the Naretha (Western Australia) meteorite has been located in museums as an un-named specimen and as two smaller specimens masquerading under the name 'Kingoonya' (or 'Kingooya'). The use of the junior synonyms with their implications of a South Australian site of find should be discontinued. INTRODUCfION Naretha meteorite, an L4 chondrite, was found in 1915 about 3 km north of the 205-mile station during construction of the Trans-Australian Railway. It was broken into at least three major pieces which were acquired by Mr John Darbyshire, Supervising Engineer for the construction of the western end of the railway (construction was proceeding simultaneously from both Kalgoorlie and Port Augusta ends - Fig. 1). Mr Darbyshire donated the meteorite to the W.A. School of Mines in Kalgoorlie where one' piece was retained and exhibited with a photograph of the reassembled meteorite (Fig. 2). A second fragment which was passed on to the Geological Survey of Western Australia was noted briefly by Simpson (1922) who first used the name 'Naretha', the name which had been given to the 205-mile station. There is strong presumptive evidence that the third fragment was passed on to Mr S.F.C. Cook of Kalgoorlie, a private collector from whose inaccurate verbal statements and undocumented collection, the subsequent confusion arose. In late 1926 Mr Cook gave a small piece of 'meteorite to Mr G.W.

Hambly Institute for Astronomy, University of Edinburgh, Blackford Hill, Edinburgh EH9 3HJ, UK Received 28 August 2003 / Accepted 28 October 2003 Abstract. In this paper we present surveys of two open clusters using photometry and accurate astrometry from the SuperCOSMOS microdensitometer. These use plates taken by the Palomar Oschin Schmidt Telescope giving a wide field (5◦ from the cluster centre in both cases), accurate positions and a long time baseline for the proper motions. Distribution functions are fitted to proper motion vector point diagrams yielding formal membership probabilities. Luminosity and mass functions are then produced along with a catalogue of high probability members. Background star contamination limited the depth of the study of Alpha Per to R = 18. Due to this the mass function found for this cluster could only be fitted with a power ξ = −α α = . +0.14 law ( (m) m ) with 0 86−0.19. However with the better seperation of the Pleiades’ cluster proper motion from the field population results were obtained down to R = 21. As the mass function produced for this cluster extends to lower masses it is possible to see the gradient becoming increasingly shallow. This mass function is well fitted by a log normal distribution. Key words. astrometry – stars: low mass, brown dwarfs – Galaxy: open clusters and associations: individual: Alpha Per, Pleiades 1.

  • Study of Eclipsing Binaries: Light Curves & O-C Diagrams Interpretation
    galaxies Review Study of Eclipsing Binaries: Light Curves & O-C Diagrams Interpretation Helen Rovithis-Livaniou Department of Astrophysics, Astronomy & Mechanics, Faculty of Physics, Panepistimiopolis, Zografos, Athens University, 15784 Athens, Greece; [email protected]; Tel.: +30-21-0984-7232 Received: 10 October 2020; Accepted: 6 November 2020; Published: 13 November 2020 Abstract: The continuous improvement in observational methods of eclipsing binaries, EBs, yield more accurate data, while the development of their light curves, that is magnitude versus time, analysis yield more precise results. Even so, and in spite the large number of EBs and the huge amount of observational data obtained mainly by space missions, the ways of getting the appropriate information for their physical parameters etc. is either from their light curves and/or from their period variations via the study of their (O-C) diagrams. The latter express the differences between the observed, O, and the calculated, C, times of minimum light. Thus, old and new light curves analysis methods of EBs to obtain their principal parameters will be considered, with examples mainly from our own observational material, and their subsequent light curves analysis using either old or new methods. Similarly, the orbital period changes of EBs via their (O-C) diagrams are referred to with emphasis on the use of continuous methods for their treatment in absence of sudden or abrupt events. Finally, a general discussion is given concerning these two topics as well as to a few related subjects. Keywords: eclipsing binaries; light curves analysis/synthesis; minima times and (O-C) diagrams 1. Introduction A lot of time has passed since the primitive observations of EBs made with naked eye till today’s space surveys.

  • Appendix I Lunar and Martian Nomenclature
    APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject.
