Elemental abundance studies of CP stars. The Silicon stars HD 87405 and HD 146555
(Universidad Nacional Autónoma de México, 2009-06-29)
In this paper we present an analysis of the Ap(Si) stars HD 87405 and HD 146555 using an ATLAS9 model atmospheres. These Chemically Peculiar (CP) stars belong to the southern hemisphere open clusters NGC 3114 and NGC 6087, ...
Dynamical evolution of titanium, strontium, and yttrium spots on the surface of the HgMn star HD11753
(EDP Sciences, 2010-02)
Aims: We gathered about 100 high-resolution spectra of three typical HgMn (mercury-manganese) stars, HD11753, HD53244, and HD221507, to search for slowly pulsating B-like pulsations and surface inhomogeneous distribution ...
THE PAN-PACIFIC PLANET SEARCH. VI. GIANT PLANETS ORBITING HD 86950 AND HD 222076
(IOP PUBLISHING LTD, 2017)
We report the detection of two new planets orbiting the K giants HD 86950 and HD 222076, based on precise radial velocities obtained with three instruments: AAT/UCLES, FEROS, and CHIRON. HD 86950b has a period of 1270 +/- ...
Optical spectroscopy of X-Mega targets in the Carina nebula, VII: on the multiplicity of Tr 16-112, HD 93343 and HD 93250
(Wiley Blackwell Publishing, Inc, 2009-09)
We present the results of a spectroscopic monitoring campaign devoted to three O-type stars in the Carina nebula. We derive the full SB2 orbital solution of the binary system Tr 16-112, an exceptional dissymmetrical system ...

Shadows cast by a warp in the HD 142527 protoplanetary disk
(IOP Publisihing, 2015)
Detailed observations of gaps in protoplanetary disks have revealed structures that drive current research on circumstellar disks. One such feature is the two intensity nulls seen along the outer disk of the HD 142527 ...
Lycopene supplementation reduces TNF-alpha via RAGE in the kidney of obese rats
(Nature Publishing Group, 2014-11-01)
The kidney is a target organ for injuries caused by advanced glycation end products (AGEs) in obesity. The receptor of AGEs (RAGE) is proinflammatory and appears to have a role in the pathogenesis of renal disease due to ...
Two Jupiter-Mass Planets Orbiting HD 154672 and HD 205739
(2008)
We report the detection of the first two planets from the N2K Doppler planet search program at the Magellan telescopes. The first planet has a mass of M sin i = 4.96 M_Jup and is orbiting the G3 IV star HD154672 with an ...
