Asteroid Lightcurve Data Archive at the Minor Planet Center Our last Newsletter reported on Brian Warner’s presentation of the Asteroid Light Curve Data Exchange Format (ALCDEF) at the AAS Division of Planetary Sciences meeting (Pasa- dena, September 2010). It is hoped that ALCDEF will become the standard format for archiving and retrieving asteroid lightcurve observa- tional data. This is important because ALCDEF enables researchers to re- trieve, manipulate, and analyze the actual observational data – brightness vs. time – which is the unambiguous phenomenon.

  • Starshade Exoplanet Data Challenge
    Starshade exoplanet data challenge a,b, a,c a Renyu Hu , * Sergi R. Hildebrandt , Mario Damiano, a a a Stuart Shaklan , Stefan Martin , and Doug Lisman a Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California, United States b California Institute of Technology, Division of Geological and Planetary Sciences, Pasadena, California, United States c California Institute of Technology, Division of Physics, Mathematics and Astronomy, Pasadena, California, United States Abstract. Starshade in formation flight with a space telescope is a rapidly maturing technology that would enable imaging and spectral characterization of small planets orbiting nearby stars in the not-too-distant future. While performance models of starshade-assisted exoplanet imaging have been developed and used to design future missions, their results have not been verified from the analyses of synthetic images. Following a rich history of using community data challenges to evaluate image-processing capabilities in astronomy and exoplanet fields, the Starshade Technology Development to TRL5 (S5), a focused technology development activity managed by the NASA Exoplanet Exploration Program, is organizing and implementing a starshade exo- planet data challenge. The purpose of the data challenge is to validate the flow down of require- ments from science to key instrument performance parameters and to quantify the required accuracy of noisy background calibration with synthetic images. This data challenge distin- guishes itself from past efforts in the exoplanet field in that (1) it focuses on the detection and spectral characterization of small planets in the habitable zones of nearby stars, and (2) it devel- ops synthetic images that simultaneously include multiple background noise terms—some observations specific to starshade—including residual starlight, solar glint, exozodiacal light, detector noise, as well as variability resulting from starshade’s motion and telescope jitter.

  • “A Brief History of Beiji (Northern Culmen)”
    “A Brief History of Beiji (Northern Culmen)” (Prepared for the 4th International Conference on the Inspiration of Astronomical Phenomena INSAP IV, Oxford University, August 3-9, 2003.) 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 points to the crucial importance of the north-pole in astrological, calendrical, and spiritual contexts. But preoccupation with this numinous region has a history far longer than the Chinese empire, founded in 221 BCE. 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 relating to the Northern Dipper, and to the void at the pivot of the heavens which lacked a pole star throughout much of the formative period of classical Chinese civilization. The discussion concludes with a hypothesis about the astral origins of the ancient form of the character used to denote the High God di. 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 By the early 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 some 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, Shang, and Zhou, consistently display such orientation.

  • A Basic Requirement for Studying the Heavens Is Determining Where In
    Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun­ damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short).

Development and Application of Tools to Characterize Transiting Astrophysical Systems A dissertation presented by Bence B´eky to The Department of Astronomy in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the subject of Astronomy and Astrophysics Harvard University Cambridge, Massachusetts 2014 April Copyright c 2014 Bence B´eky All rights reserved. Dissertation Advisor: Author: Dr. Matthew Holman Bence B´eky Development and Application of Tools to Characterize Transiting Astrophysical Systems Abstract Since the discovery of the first exoplanets (planets outside our Solar System) more than 20 years ago, there has been an increasing need for photometric and spectroscopic models to characterize these systems. While imaging has been used extensively for Solar System bodies and extended objects like galaxies, the small angular extent of typical planetary systems makes it difficult or impossible to resolve them. Spatially integrated observations like measuring the total brightness or spectrum, however, can be conducted at a resonable cost. This thesis focuses on photometric models in the context of transiting systems, which exhibit a number of phenomena that can be exploited for characterization. First, we showcase the popular methods of transiting exoplanet discovery and characterization by ground based observations on the hot Jupiter HAT-P-27b. We demonstrate how transits allow us to constrain planetary mass, radius, and orbital inclination, which would not be possible based only on, for example, radial velocity measurements. Next, we perform reflection spectroscopy on HAT-P-1b, another hot Jupiter, using the binary companion of the host star as a reference to remove systematic errors from iii the signal.
