Wilson et al.: High Precision Photometry of Transiting Exoplanets High Precision Photometry of Transiting Exoplanets Maurice Wilson1,2, Jason Eastman2, and John Johnson2 1Embry-Riddle Aeronautical University 2Harvard-Smithsonian Center for Astrophysics In order to increase the rate of finding, confirming, and characterizing Earth-like exoplanets, the MINiature Exoplanet Radial Velocity Array (MINERVA) was recently built with the purpose of obtaining the spectroscopic and photometric precision necessary for these tasks. Achieving the satisfactory photometric precision is the primary focus of this work. This is done with the four telescopes of MINERVA and the defocusing technique. The satisfactory photometric precision derives from the defocusing technique. The use of MINERVA’s four telescopes benefits the relative photometry that must be conducted. Typically, it is difficult to find satisfactory comparison stars within a telescope’s field of view when the primary target is very bright. -

“Astrometry/Photometry of Solar System Objects After Gaia”
ISSN 1621-3823 ISBN 2-910015-77-7 NOTES SCIENTIFIQUES ET TECHNIQUES DE L’INSTITUT DE MÉCANIQUE CÉLESTE S106 Proceedings of the Workshop and colloquium held at the CIAS (Meudon) on October 14-18, 2015 “Astrometry/photometry of Solar System objects after Gaia” Institut de mécanique céleste et de calcul des éphémérides CNRS UMR 8028 / Observatoire de Paris 77, avenue Denfert-Rochereau 75014 Paris Mars 2017 Dépôt légal : Mars 2017 ISBN 2-910015-77-7 Foreword The modeling of the dynamics of the solar system needs astrometric observations made on a large interval of time to validate the scenarios of evolution of the system and to be able to provide ephemerides extrapolable in the next future. That is why observations are made regularly for most of the objects of the solar system. The arrival of the Gaia reference star catalogue will allow us to make astrometric reductions of observations with an increased accuracy thanks to new positions of stars and a more accurate proper motion. The challenge consists in increasing the astrometric accuracy of the reduction process. More, we should think about our campaigns of observations: due to this increased accuracy, for which objects, ground based observations will be necessary, completing space probes data? Which telescopes and targets for next astrometric observations? The workshop held in Meudon tried to answer these questions. Plans for the future have been exposed, results on former campaigns such as Phemu15 campaign, have been provided and amateur astronomers have been asked for continuing their participation to new observing campaigns of selected objects taking into account the new possibilities offered by the Gaia reference star catalogue. -

This qualitative tradition was first developed in the ninth century in the course of studying ancient Latin texts on cosmology and astronomy. The diagrams, used to represent different phenomena and aspects of planetary motion, continued as long as they were found useful for teaching, for exposing questions, or for proposing theoretical positions. The history of this tradition of planetary diagrams indicates a constant concern for qualitative theory and the co-existence of both qualitative and quantitative plane- tary theory after the introduction of the Greco-Arabic mathematical tradition of planetary astronomy in twelfth-century Europe. In the sixteenth century the same qualitative tradition continued as a source for approaches to new phenomena and problems. 2 THE BEGINNINGS IN CAROLINGIAN EUROPE 2.1 ASTRONOMY AND COMPUTUS BEFORE 800 From the sixth century to the twelfth century in Western Europe there was no direct influence of Greek works in the exact sciences. -

A Needs Analysis Study of Amateur Astronomers for the National Virtual Observatory : Aaron Price1 Lou Cohen1 Janet Mattei1 Nahide Craig2
A Needs Analysis Study of Amateur Astronomers For the National Virtual Observatory : Aaron Price1 Lou Cohen1 Janet Mattei1 Nahide Craig2 1Clinton B. Ford Astronomical Data & Research Center American Association of Variable Star Observers 25 Birch St, Cambridge MA 02138 2Space Sciences Laboratory University of California, Berkeley 7 Gauss Way Berkeley, CA 94720-7450 Abstract Through a combination of qualitative and quantitative processes, a survey was con- ducted of the amateur astronomy community to identify outstanding needs which the National Virtual Observatory (NVO) could fulfill. This is the final report of that project, which was conducted by The American Association of Variable Star Observers (AAVSO) on behalf of the SEGway Project at the Center for Science Educations @ Space Sci- ences Laboratory, UC Berkeley. Background The American Association of Variable Star Observers (AAVSO) has worked on behalf of the SEGway Project at the Center for Science Educations @ Space Sciences Labo- ratory, UC Berkeley, to conduct a needs analysis study of the amateur astronomy com- munity. The goal of the study is to identify outstanding needs in the amateur community which the National Virtual Observatory (NVO) project can fulfill. The AAVSO is a non-profit, independent organization dedicated to the study of vari- able stars. It was founded in 1911 and currently has a database of over 11 million vari- able star observations, the vast majority of which were made by amateur astronomers. The AAVSO has a rich history and extensive experience working with amateur astrono- mers and specifically in fostering amateur-professional collaboration. AAVSO Director Dr. Janet Mattei headed the team assembled by the AAVSO. -
