Almahata Sitta (=asteroid 2008 TC3) and the search for the ureilite parent body
This article explores what the recovery of 2008 TC3 in the form of the Almahata Sitta meteorites may tell us about the source region of ureilites in the main asteroid belt. An investigation is made into what is known about asteroids with roughly the same spectroscopic signature as 2008 TC3. A population of low-inclination near-Earth asteroids is identified with spectra similar to 2008 TC3. Five...
متن کاملMagnetism and mineralogy of Almahata Sitta polymict ureilite (= asteroid 2008 TC3): Implications for the ureilite parent body magnetic field
The Almahata Sitta meteorite is the first case of recovered extraterrestrial material originating from an asteroid that was detected in near Earth space shortly before entering and exploding in the high atmosphere. The aims of our project within the 2008 TC3 consortium were investigating Almahata Sitta’s (AS) magnetic signature, phase composition and mineralogy, focussing on the opaque minerals...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولDisequilibrium Fractional Melting on the Ureilite Parent Body
Introduction: Ureilites are carbon-rich ultramafic achondrites [1] thought to represent the mantle (residues and minor cumulates) of a parent body that was stratified in mg, pyroxene abundance, and pyroxene type due to the pressure dependence of smelting [2]. Because there are no basaltic ureilites, we lack direct information about melts on the ureilite parent body (UPB). Insights from feldspat...
