Habitat selection by Torrent Ducks (Merganetta armata armata) in Central Chile: Conservation implications of hydropower production
(2013)
The Torrent Duck (Merganetta armata) inhabits the torrential rivers of the Andean mountains. As part of a long-term study, two rivers important for hydroelectric production were surveyed in Central Chile. Monthly indices ...
Detailed dynamic, geometric and supraglacial moraine data for Glaciar Pio XI, the only surge-type glacier of the Southern Patagonia Icefield
(Cambridge University Press, 2016)
In contrast to the general trend for glaciers of the Southern Patagonia Icefield, Glaciar Pio XI has experienced a large cumulative frontal advance since 1945. In an effort to better understand this advancing behaviour, ...
Tracing extended low-velocity shocks through SiO emission Case study of the W43-MM1 ridge
(EDP Sciences, 2016)
Aims. Previous literature suggests that the densest structures in the interstellar medium form through colliding flows, but patent evidence of this process is still missing. Recent literature proposes using SiO line emission ...
Four new planets around giant stars and the mass-metallicity correlation of planet-hosting stars
(EDP Sciences, 2016)
Context. Exoplanet searches have revealed interesting correlations between the stellar properties and the occurrence rate of planets. In particular, different independent surveys have demonstrated that giant planets are ...
Giant planets around two intermediate-mass evolved stars and confirmation of the planetary nature of HIP 67851c
(EDP Sciences, 2015)
Context. Precision radial velocities are required to discover and characterize exoplanets. Optical spectra that exhibit many hundreds of absorption lines can allow the m s(-1) precision levels required for this work. After ...

Signals embedded in the radial velocity noise Periodic variations in the τ Ceti velocities
(EDP Sciences, 2013)
Context. The abilities of radial velocity exoplanet surveys to detect the lowest-mass extra-solar planets are currently limited by a
combination of instrument precision, lack of data, and “jitter”. Jitter is a general ...
Turbulent transport mechanisms on the heat confinement in tunnels by using low-velocity air curtains
(Pergamon-Elsevier, 2020)
Simulations with the Fire Dynamics Simulator (FDS) were performed to study the ability of Double Stream-Twin Jets (DS-TJ) air curtains to confine heat. Numerical simulations aimed to model a 1:34 scale tunnel, equipped ...
Analysis of combined radial velocities and activity of BD+20 1790: evidence supporting the existence of a planetary companion
(EDP Sciences, 2015)
Context. In a previous paper we reported a planetary companion to the young and very active K5Ve star BD+20 1790. We found
that this star has a high level of stellar activity (log R HK = −3.7) that manifests in a plethora ...
Submillimeter H2O masers in water-fountain nebulae
(EDP Sciences, 2014)
We report the first detection of submillimeter water maser emission toward water-fountain nebulae, which are post-AGB stars that exhibit high-velocity water masers. Using APEX we found emission in the ortho-H2O (1029 → 936) ...
