Applications of Solar Wind Particle Impact Simulations at Lunar Magnetic Anomalies to the Study of Lunar Swirls
47th Lunar and Planetary Science Conference (2016) 2648.pdf APPLICATIONS OF SOLAR WIND PARTICLE IMPACT SIMULATIONS AT LUNAR MAGNETIC ANOMALIES TO THE STUDY OF LUNAR SWIRLS. C. J. Tai Udovicic1, G. Y. Kramer2, and E. M.

Introduction: Lunar swirls are high albedo features highlands often appear to have swirl-like anomalies due that exhibit low spectral maturity. They have been to their complicated topography. To mitigate this, we identified at various sites on the Moon, and all coincide generated a slope map from the WAC GLD100 (SLP), with a lunar magnetic anomaly (magnomaly) [1], which we overlayed with the WAC 643 nm normalized although not all magnomalies have an identifiable swirl. reflectance image to distinguish high albedo swirls from The leading hypothesis for lunar swirl origin is high albedo slopes. Even so, after one pass of the region, presented in [2] as magnetic field standoff of the solar only about half of the swirls could be detected with this wind which causes uneven space weathering at the swirl method alone. The remaining half were found after surface. This hypothesis fails to explain why lunar using particle simulations as a guide. swirls are observed at some but not all of the magnetic Solar wind particle tracking simulations: We anomalies present on the Moon. To investigate the solar used the 2D solar wind particle tracking simulation wind standoff hypothesis further and to improve swirl presented in [2]. -

Simulations of Particle Impact at Lunar Magnetic Anomalies and Comparison with Spectral Observations
Simulations of Particle Impact at Lunar Magnetic Anomalies and Comparison with Spectral Observations Erika Harnett∗ Department of Earth and Space Science, University of Washington,Seattle, WA 98195-1310, USA Georgiana Kramer Lunar and Planetary Institute, 3600 Bay Area Blvd, Houston, TX 77058, USA Christian Udovicic Department of Physics, University of Toronto, 60 St George St,Toronto, ON M5S 1A7, Canada Ruth Bamford RAL Space, STFC, Rutherford Appleton Laboratory,Chilton, Didcot Ox11 0Qx, UK (Dated: November 5, 2018) Ever since the Apollo era, a question has remained as to the origin of the lunar swirls (high albedo regions coincident with the regions of surface magnetization). Different processes have been proposed for their origin. In this work we test the idea that the lunar swirls have a higher albedo relative to surrounding regions because they deflect incoming solar wind particles that would otherwise darken the surface. 3D particle tracking is used to estimate the influence of five lunar magnetic anomalies on incoming solar wind. The regions investigated include Mare Ingenii, Gerasimovich, Renier Gamma, Northwest of Apollo and Marginis. Both protons and electrons are tracked as they interact with the anomalous magnetic field and impact maps are calculated. The impact maps are then compared to optical observations and comparisons are made between the maxima and minima in surface fluxes and the albedo and optical maturity of the regions. Results show deflection of slow to typical solar wind particles on a larger scale than the fine scale optical, swirl, features. It is found that efficiency of a particular anomaly for deflection of incoming particles does not only scale directly with surface magnetic field strength, but also is a function of the coherence of the magnetic field. -

It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe. Astronomy is one of the oldest sciences. Prehistoric cultures left behind astronomical artifacts such as the Egyptian monuments and Stonehenge, and early civilizations such as the Babylonians, Greeks, Chinese, Indians, and Maya performed methodical observations of the night sky. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy A giant Hubble mosaic of the Crab Nebula, a supernova remnant has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, the making of calendars, and even astrology, but professional astronomy is nowadays often considered to be synonymous with astrophysics. -
