Lowermost mantle anisotropy near the eastern edge of the Pacific LLSVP: constraints from SKS–SKKS splitting intensity measurements
(Oxford University Press, 2017-05-05)
Seismic anisotropy has been documented in many portions of the lowermost mantle, with particularly strong anisotropy thought to be present along the edges of large low shear velocity provinces (LLSVPs). The region surrounding ...
PCA analysis of the nighttime anomaly in far-from-geomagnetic pole regions from VTEC GNSS data
(Terra Scientific Publishing, 2015-12)
The Weddell Sea Anomaly (WSA) is defined when the nighttime plasma density is greater than the daytime density in the area near the Weddell Sea, more specifically in the region limited by 50° S-70°S in latitude and 225° ...
A very unusual cluster of multiple small impact craters probably created by the impact of a split cometary nucleus in Patagonia
(Fundación de Historia Natural Félix de Azara, 2019-08)
Se hace aquí un análisis detallado del evento de impacto cósmico de Bajada del Diablo (S 42º 45’, W 67º 30’). El evento ocurrió probablemente en el Pleistoceno Medio (780.000 a 130.000 años atrás), y originalmente unos 550 ...

Observations of an Unexpected Meteor Shower Outburst at High Ecliptic Southern Latitude and Its Potential Origin
(Institute of Physics Publishing, 2020-05)
A strong and unexpected meteor shower outburst was observed by the Southern Argentina Agile MEteor Radar Orbital System (SAAMER-OS) at high southern ecliptic latitude within the South Toroidal region. The outburst, which ...
The Ultraviolet Radiation Environment around M dwarf Exoplanet Host Stars
(IOP Publishing, 2013-02)
The spectral and temporal behavior of exoplanet host stars is a critical input to models of the chemistry and evolution of planetary atmospheres. Ultraviolet photons influence the atmospheric temperature profiles and ...
The Cerro Guanaco mass movements: A geophysical and morphometric approach on a megalandslide in the Fuegian Andes (Southern Patagonia)
(Pergamon-Elsevier Science Ltd, 2020-08)
The Fuegian Andes, in the southernmost part of South America, are characterized by a relatively young deglacial landscape, where the glacial erosive relief is strongly influenced by regional-scale geological structures, ...

The dynamical evolution of escaped Jupiter Trojan asteroids, link to other minor body populations
(Academic Press Inc Elsevier Science, 2019-02)
The Jupiter Trojans constitute an important asteroidal population both in number and also in relation to their dynamical and physical properties. They are asteroids located around L4 and L5 Lagrangian points on relatively ...
