(Oxford University Press, 2020)We report the discovery of a new ultrashort period (USP) transiting hot Jupiter from the Next Generation Transit Survey (NGTS). NGTS-10b has a mass and radius of 2.162(-0.107)(+0.092) M-J and 1.205(-0.083)(+0.117) R-J and ...
-
(IOP Publishing, 2020)We report the discovery of NGTS-11 b (=TOI-1847b), a transiting Saturn in a 35.46 day orbit around a mid K-type star (T-eff = 5050 +/- 80 K). We initially identified the system from a single-transit event in a TESS full-frame ...
-
(Oxford University Press, 2020)We report the discovery of the transiting exoplanet NGTS-12b by the Next Generation Transit Survey (NGTS). The host star, NGTS-12, is a V = 12.38 mag star with an effective temperature of T-eff = 5690 +/- 130 K. NGTS-12b ...
-
(Oxford University Press, 2021)We present the discovery of NGTS-19b, a high-mass transiting brown dwarf discovered by the Next Generation Transit Survey. We investigate the system using follow-up photometry from the South African Astronomical Observatory, ...
-
(Oxford University Press, 2018)We present the discovery of NGTS-1b, a hot Jupiter transiting an early M-dwarf host (T-eff,(*) = 3916 (+71)(-63) K) in a P = 2.647 d orbit discovered as part of the Next Generation Transit Survey (NGTS). The planet has a ...
-
(Oxford University Press, 2019)We report the discovery of NGTS-4b, a sub-Neptune-sized planet transiting a 13th magnitude K-dwarf in a 1.34 d orbit. NGTS-4b has a mass M = 20.6 ± 3.0M⊕ and radius R = 3.18 ± 0.26 R⊕, which places it well within the ...
-
(Oxford Unv Press, 2020)We report the discovery, by the next generation transit survey (NGTS), of two hot Jupiters NGTS-8b and NGTS-9b. These orbit a V = 13.68 K0V star (T-eff = 5241 +/- 50 K) with a period of 2.49970 d, and a V = 12.80 F8V star ...

(Universidad Arturo Prat, 2015)La tríada “Libertad-Igualdad-Fraternidad” se ha entendido como un valioso legado de la Ilustración francesa, materializado por la revolución de 1789 e incluido en el proyecto de la Modernidad. No obstante, dichos conceptos ...
-
(Wiley-Blackwell, 2016)Much research debates whether properties of ecological networks such as nestedness and connectance stabilise biological communities while ignoring key behavioural aspects of organisms within these networks. Here, we ...
-
(Elsevier, 2012)In this contribution the synthesis and polymerization activity of the nickel complexes [NiBr2{N0-(2,6- diisopropylphenyl)-N-[1-(2,6-diisopropylphenylimine)ethyl]-N-(2,3,4,5,6-pentafluorophenyl)acetam idine}] (2), ...

(ELSEVIER, 2010)We characterize inverse limits of nilsystems in topological dynamics, via a structure theorem for topological dynamical systems that is an analog of the structure theorem for measure preserving systems. We provide two ...
-
(IOP Publishing, 2020)We present evidence for localized deviations from Keplerian rotation, i.e., velocity "kinks," in 8 of the 18 circumstellar disks observed by the DSHARP program: DoAr 25, Elias 2-27, GW Lup, HD 143006, HD 163296, IM Lup, ...
-
(Universidad de Chile, 2017)El presente estudio tiene por objeto identificar características de la niñez y adolescencia inmigrante en Chile, a fin de aportar elementos al diseño de una política pública enfocada en esta temática. La investigación busca ...
-
(Mineralogical Society of America, 2018)The nitrate deposits of the Atacama Desert are unique when one considers that in most surface environments nitrate is produced or consumed by biological processes and is easily washed away by rain. Nitrate deposits have ...

Nitrite reduction on a multimetallic porphyrin/polyoxotungstate layer-by-layer modified electrodes (Elsevier, 2016)Electro and photoelectrochemical reduction of nitrite in aqueous solution was studied using a multielectrocatalysts modified ITO electrode. ITO modification was carried out using the layer-by-layer (LBL) method, where ...

(Nature Publishing Group, 2019)Heart failure with preserved ejection fraction (HFpEF) is a common syndrome with high morbidity and mortality for which there are no evidence-based therapies. Here we report that concomitant metabolic and hypertensive ...
