(ESO, 2005)Three nearby star candidates were selected as bright 2MASS point sources without associated optical sources, i.e. with potentially large proper motions, subsequently confirmed by multi-epoch optical data from the SuperCOSMOS ...

(Schloss Dagstuhl- Leibniz-Zentrum fur Informatik GmbH, Dagstuhl Publishing, 2017)In this paper we present distributed property-testing algorithms for graph properties in thecongestmodel, with emphasis on testing subgraph-freeness. Testing a graph propertyPmeansdistinguishing graphsG= (V,E)having ...
-
(ESO, 2014)For the past six years we have carried out a search for massive planets around main sequence and evolved stars in the open cluster M67, using radial velocity (RV) measurements obtained with HARPS at ESO (La Silla), SOPHIE ...
-
(EDP Science, 2020)We report the confirmation and mass determination of three hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HIP 65Ab (TOI-129, TIC-201248411) is an ultra-short-period Jupiter orbiting a ...

(AMER GEOPHYSICAL UNION, 2006-09-26)We forward modeled the Bouguer anomaly in a region encompassing the Pacific Ocean (85 degrees W) and the Andean margin (60 degrees W) between northern Peru (5 degrees S) and Patagonia (45 degrees S). The three-dimensional ...
-
(Taylor and Francis Ltd., 2018)The stability graph method is widely used for open stope mine design. During the development of the method the effect of induced stresses were included by using two-dimensional or limited three-dimensional stress analysis. ...
-
(Oxford University Press, 2016)We use seismic tomography to investigate the state of the supraslab mantle beneath northern Chile, a part of the Nazca-South America Plate boundary known for frequent megathrust earthquakes and active volcanism. We performed ...
-
(Elsevier, 2016)Magnetotelluric (MT) data were recorded to investigate a geothermal prospect in northern Chile. The exploration area is located in the Atacama region, at the southern edge of the Chilean Altiplano, at an altitude of similar ...
-
(IOP Publishing, 2020)Offsets of molecular line emission peaks from continuum peaks are very common but frequently difficult to explain with a single spherical cloud chemical model. We propose that the spatial projection effects of an irregular ...
-
(Amer Geophysical Union, 2015)Lazufre volcanic center, located in the central Andes, is recently undergoing an episode of uplift, conforming one of the most extensive deforming volcanic systems worldwide, but its magmatic system and its connection with ...
-
(Oxford University Press, 2020)The inner parsec of our Galaxy contains tens of Wolf-Rayet stars whose powerful outflows are constantly interacting while filling the region with hot, diffuse plasma. Theoretical models have shown that, in some cases, the ...
-
(Churchill Livingstone, 2019)The purpose of this study was to evaluate volumetric and dentoskeletal changes in 21 patients with active unilateral condylar hyperplasia (AUCH) after proportional condylectomy. A split-mouth design was used: control group ...
-
(MARY ANN LIEBERT INC, 2006-04)Information technologies are increasingly helping to integrate and socially include people with visual disabilities. Computing technologies have contributed grandly to attain this goal through innovative techniques and ...
-
(IOP, 2015)We report here a study of gas, dust and star formation rates (SFRs) in the molecular cloud complexes (MCCs) surrounding the giant HII region RCW106 using 12CO and 13CO(1-0) data from the Three- mm Ultimate Mopra Milky ...

Threshold condition for global existence and blow-up to a radially symmetric drift–diffusion system (Elsevier, 2012)For a class of drift–diffusion systems Kurokiba et al. [M. Kurokiba, T. Nagai, T. Ogawa, The uniform boundedness and threshold for the global existence of the radial solution to a drift–diffusion system, Commun. Pure ...

(Wiley-VCH Verlag, 2019)The tidal disruption of a star by a nuclear supermassive black hole was predicted in the 1970s and first confirmed by soft X-ray flares seen from quiescent galaxies in the ROSAT all-sky survey. We report here on the discovery ...
-
(American Geophysical Union, 2013)We located continuous seismic tremor with coherent amplitude wave trains in the Chile ridge subduction region (~46.5 S) in two clusters north and south of the Chonos Archipelago, between the Chile trench and the North ...
