    202 Chapter 5 FUTURE WORK There is more work is planned for these projects. Some of the proposed future work fell out of the questions and problems that arise while first attempting to solve a problem. Some of it was originally intended to be encompassed in the thesis work, but work at an earlier stage grew to dominate the project as a result of the sheer volume of data available. Many questions were left unanswered in the work described in Chapter 4. It is not clear why the MM5 does not predict the secondary winds that clearly must exist in the current wind regime. These winds do not appear in GFDL GCM model runs, and they may not exist in any current atmospheric model. It is possible that they are produced by rare storms (i.e., storms that occur once a decade or century), and I would like to look into the possibility of observing or predicting these storms. The MM5 also does not predict winds strong enough to lift basaltic grains into saltation. This may simply be a problem of model resolution, and it is not a difficult prospect to run the model at a higher resolution and/or to output the strongest hourly winds at each grid point rather than the winds at the top of each hour. There is also the problem that the MM5 is meant to hold subgrids that are no more than three times smaller than their parent grids – and yet our model runs at a scale of 10 km were more than an order of magnitude higher resolution than the parent grid.

  • Surface Characteristics of Transneptunian Objects and Centaurs from Photometry and Spectroscopy
    Barucci et al.: Surface Characteristics of TNOs and Centaurs 647 Surface Characteristics of Transneptunian Objects and Centaurs from Photometry and Spectroscopy M. A. Barucci and A. Doressoundiram Observatoire de Paris D. P. Cruikshank NASA Ames Research Center The external region of the solar system contains a vast population of small icy bodies, be- lieved to be remnants from the accretion of the planets. The transneptunian objects (TNOs) and Centaurs (located between Jupiter and Neptune) are probably made of the most primitive and thermally unprocessed materials of the known solar system. Although the study of these objects has rapidly evolved in the past few years, especially from dynamical and theoretical points of view, studies of the physical and chemical properties of the TNO population are still limited by the faintness of these objects. The basic properties of these objects, including infor- mation on their dimensions and rotation periods, are presented, with emphasis on their diver- sity and the possible characteristics of their surfaces. 1.

  • Martian Crater Morphology
    ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter.

The surveyed elements include proton-capture (O, Na, Mg, Al, Si), α-capture (Ca, Ti), Fe-peak (Sc, V, Mn, Co, Ni, Cu), and neutron-capture elements (Y, Zr, Ba, La, Ce, Nd, Eu, Dy). The analysis is fully consistent with that presented for twenty GCs in previous papers of this series. Stars in NGC 362 seem to be clustered into two discrete groups along the Na-O anti-correlation with a gap at [O/Na] ∼ 0 dex.

  • 2002 Convention Bulletin
    STELLAFANE The 67th Convention of Amateur Telescope Makers on Breezy Hill in Springfield, Vermont. Friday, August 9th and Saturday, August 10th, 2002 "For it is true that astronomy, from a popular standpoint, is handicapped by the inability of the average workman to own an expensive astronomical telescope. It is also true that if an amateur starts out to build a telescope just for fun he will find, before his labors are over, that he has become seriously interested in the wonderful mechanism of our universe. And finally there is understandably the stimulus of being able to unlock the mysteries of the heavens by a tool fashioned by one's own hand." Russell W. Porter, March 1923 -- Founder of Stellafane The Stellafane Convention is a gathering of amateur telescope makers. The Convention was started in 1926 to give amateur telescope makers an opportunity to gather, to show off their creations and teach each other telescope making and mirror grinding techniques. If you have made your own telescope, we strongly encourage you to display it in the telescope fields near the Pink Clubhouse. If you wish, you can enter it in the mechanical and/or optical competition. There are also mirror grinding and telescope making demonstrations, technical lectures on telescope making and the presentation of awards for telescope design and craftsmanship. Vendor displays and the retail sale of commercial products are not permitted. For additional information please check out the home page www.stellafane.com. Enjoy the convention! PLEASE NOTE AN IMPORTANT SCHEDULE CHANGE DURING CONVENTION: The optical judging has been re- scheduled for Friday night! There will be no optical judging Saturday night unless clouds interfere with the optical competition on Friday.

AN ANALYSIS OF THE DISTRIBUTION OF GLOBULAR CLUSTERS WITH POSTCOLLAPSE CORES IN THE GALAXY David F. Chernoff1 Center for Radiophysics and Space Research, Cornell University AND S. Djorgovski2 California Institute of Technology Received 1988 May 6 ¡accepted 1988 September 20 ABSTRACT We present a new compilation of structural parameters for Galactic globular clusters, based on the data from the complete survey published by Djorgovski, King, and collaborators in 1984, 1986, and 1987 and the e find that the s aboutIhZTth' the ?Galactic| t center than di t nbutionthe distribution of the post^ore-collapsed of the King model (PCC) (KM) clustersclusters. is Withinmuch morethe KM concentrated family a similar trend exists: centrally condensed KM clusters are found, on average, at smaller galactocentric radii To deal with the problem of Galactic obscuration, we used a distance-independent analysis, similar to one devel- oped and published by Frenk and White in 1982. We analyzed the shapes of the KM and PCC cluster systems; they are each consistent with a symmetrical distribution of the clusters about the Galactic center At hxed distance from the center, the clusters at smaller heights above the plane (and thus the less inclined orbits) are marginally more concentrated. The data indicate that the more concentrated KM clusters tend to have C eS ther hand the cc clusters KMK M clusters.H nTr^Th The pPCCiï clusters^ ° show, signs’. ofP tidal distortions are lessm theirluminous envelopes: than thetheir highest major concentrationaxes tend to point toward the Galactic center; the KM clusters show no such effect.
