Modeling Surface Stresses on Europa
Introduction: Modeling of the surface stresses on Europa has been performed to date, considering tidal, nonsynchronous, and polar wander sources of stress [3-6]. The results of such models can be used to match lineament orientation with the candidate stress patterns. Moreover, stratigraphic analysis can be used in combination with stress modeling to infer the evolution of Europa’s surface back ...
متن کاملLifetime of Organic Molecules at the Surface of Europa
Introduction: The possible existence of an ocean beneath the surface of Jupiter’s icy moon Europa has fueled scientific interest in this tiny world. Liquid water is a crucial element in the development of life on Earth, and if present on Europa, increases the likelihood of finding life there as well. Hydrothermal vents on the Europan ocean floor could provide habitat for microbes as well as gen...
متن کاملSalts and Radiation Products on the Surface of Europa
The surface of Europa could contain the compositional imprint of a underlying interior ocean, but competing hypotheses differ over whether spectral observations from the Galileo spacecraft show the signature of ocean evaporates or simply surface radiation products unrelated to the interior. Using adaptive optics at the W.M. Keck Observatory, we have obtained spatially resolved spectra of most o...
متن کاملHydrated Minerals on Europa ’ S Surface
Introduction: We have reanalyzed some of the Near Infrared Mapping Spectrometer (NIMS) data from the Galileo mission that were recently reprocessed to improve their calibration and remove radiation spikes and other imperfections [1]. Here we report on some results for two image cubes for the Galilean satellite Europa. We concentrate on the water spectral features in the 07-3-μm spectral region ...
متن کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
