Water worlds in N-body simulations with fragmentation in systems without gaseous giants
(EDP Sciences, 2020-08)
We analyze the formation and evolution of terrestrial-like planets around solar-type stars in the absence of gaseous giants. In particular, we focus on the physical and dynamical properties of those that survive in the ...
Assessing land use and land cover change in Los Molinos reservoir watershed and the effect on the reservoir water quality
(Pergamon-Elsevier Science Ltd, 2021-06-23)
Understanding and modelling land use and land cover (LULC) change have become one of the major subjects of interest for environmental management due to the negative effects that human activities generate on the normal ...
Fluvial and aeolian dynamics of the Santa María River in the Cafayate depression (Salta Province, NW Argentina)
(Journal Maps, 2018-09)
A geomorphological cartography of the Cafayate depression (NW Argentina) at a scale of 1:20,000 is presented. TheMain Mapwas made with satellite images from 2009 to 2016 and aerial photographs from various dates. The area ...
Spatiotemporal dynamics of Lutzomyia longipalpis and macro-habitat characterization using satellite images in a leishmaniasis-endemic city in Argentina
(Wiley Blackwell Publishing, Inc, 2018-09-09)
The spatiotemporal population dynamics of Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera: Psychodidae) were evaluated in a city in Argentina in which visceral leishmaniasis is endemic. Over 14 sampling sessions, 5244 ...
Stability criteria for wide binary stars harboring Oort Clouds
(EDP Sciences, 2018-03)
Context. In recent years, several numerical studies have been done in the field of the stability limit. Although, many of them included the analysis of asteroids or planets, is not possible to find in the literature any ...
Emerging trends in a period-radius distribution of close-in planets
(IOP Publishing, 2013-01)
We analyze the distribution of extrasolar planets (both confirmed and Kepler candidates) according to their orbital periods P and planetary radii R. Among confirmed planets, we find compelling evidence for a paucity of ...
Absolute densities in exoplanetary systems: Photodynamical modelling of Kepler-138
(Wiley Blackwell Publishing, Inc, 2018-07)
In favourable conditions, the density of transiting planets inmultiple systems can be determined from photometry data alone. Dynamical information can be extracted from light curves, providing modelling is done self-consistently, ...
Dust trapping around Lagrangian points in protoplanetary disks
(EDP Sciences, 2020-10)
Trojans are defined as objects that share the orbit of a planet at the stable Lagrangian points L4 and L5. In the Solar System, these bodies show a broad size distribution ranging from micrometer (μm) to centimeter (cm) ...
Collisions between amorphous carbon nanoparticles: Phase transformations
(EDP Sciences, 2020-09)
Context. Collisions of nanoparticles (NPs) occur in dust clouds and protoplanetary disks. Aims. Sticking collisions lead to the growth of NPs, in contrast to bouncing or even fragmentation events and we aim to explore these ...
Variability and 20-year trends in satellite-derived surface chlorophyll concentrations in large marine ecosystems around South and Western central America
(Frontiers Media S. A, 2017-11)
Marine ecosystems are under the increasing stress of natural and anthropogenic climate variability and change. Knowledge of the patterns of distribution of chlorophyll concentrations as an indicator of phytoplankton ...
