    • Terrazas Vargas, Juan; Corcione, L.; Lattanzi, M.G.; Gai, M. (IOP Publishing, 2017-07-01)
      We evaluate the astrometric and photometric implications of a series of laboratory tests conducted to study the effects of radiation damage caused by solar protons in space-borne charge coupled devices (CCDs). The photometric ...
    • Flock, Mario; Nelson, Richard P.; Turner, Neal J.; Bertrang, Gesa H.-M.; Carrasco González, Carlos; Henning, Thomas; Lyra, Wladimir; Teague, Richard (IOP Publishing Ltd, 2017)
      Planets are born in protostellar disks, which are now observed with enough resolution to address questions about internal gas flows. Magnetic forces are possibly drivers of the flows, but ionization state estimates suggest ...
    • Thi, W. F.; Kamp, I.; Woitke, P.; Van der Plas, Gerrit; Bertelsen, R.; Wiesenfeld, L. (EDP Sciences, 2013)
      Context. The carbon monoxide (CO) ro-vibrational emission from discs around Herbig Ae stars and T Tauri stars with strong ultraviolet emissions suggests that fluorescence pumping from the ground X1Σ+ to the electronic A1Π ...

      The El Tatio geothermal field in the Chilean Altiplano contains hydrothermal silica sinter deposits overlaying glacial and volcanic units, providing an opportunity to constrain the timing of deglaciation and volcanic ...
    • Rodríguez, Fernando; Ponce, Diana; Berward, Francisco J.; Lopetegui, Bernardita; Cassorla Goluboff, Fernando; Aracena, Mariana (Wiley-Liss Inc., 2019)
      We report the case of a 14 years and 8 months girl, who is the first child of nonconsanguineous parents, with short stature, obstructive hypertrophic cardiomyopathy, multiple facial lentigines, high and wide forehead, ...
    • Soto, M. G.; Jenkins, James Stewart; Jones Fernández, Matías Ignacio (Oxford University Press, 2015)
      A recent reanalysis of archival data has lead several authors to arrive at strikingly different conclusions for a number of planet-hosting candidate stars. In particular, some radial velocities (RVs) measured using Fiber-fed ...
    • Sepúlveda Valenzuela, Sergio; Padilla, Cristóbal (SPRINGER, 2008-11)
      Debris and mudflows are some of the main geological hazards in the mountain foothills of the Chilean capital city of Santiago. There, the risk of flows triggered in the basins of ravines that drain the range into the ...
    • Valencia-Gálvez, P.; Peña, O.; Moris, S.; Barahona, P. (Sociedad Chilena de Quimica, 2019)
      Polycrystalline thiospinels CuCr2-xSnxS4 (x = 0.4, 0.8, 1.0 and 1.4) were synthesized via conventional solid-state reaction. The samples were characterized by powder X-ray diffraction (XRD), energy-dispersive X-ray analysis ...
    • Martínez Concha, Francisco; Henríquez, Rodrigo (PERGAMON-ELSEVIER SCIENCE LTD, 2007-07)
      A model of the static equilibrium in the real estate market is studied in this paper and a solution algorithm is proposed. Consumers and real estate suppliers are assumed to have idiosyncratic differences, which are ...
    • Fontbona Torres, Joaquín; Méléard, S. (AMER MATHEMATICAL SOC, 2008)
      We consider incompressible 2d Navier-Stokes equations in the whole plane with external nonconservative forces fields. The initial data and external field are functions assumed to satisfy only slight integrability properties. ...
    • Loguercio, A. D.; Rezende, M.; Gutierrez, M. F.; Costa, T. F.; Armas-Vega, A.; Reis, A. (Elsevier Ltd, 2019)
