Infall of galaxies onto groups
(EDP Sciences, 2020-10)
The growth of the structure within the Universe manifests in the form of accretion flows of galaxies onto groups and clusters. Thus, the present-day properties of groups and their member galaxies are influenced by the ...
SAFARI - I. A SPHERE discovery of a super metal-rich M-dwarf companion to the star HD 86006
(Oxford University Press, 2018)
We report the direct detection of a fully convective, early-to-midM-dwarf companion orbiting the star HD 86006, using ESO-SPHERE during Science Verification as part of the SAFARI program. HARPS+CORALIE radial velocity ...
Open cluster radial velocity determination from observations at observatório Pico dos Dias
(International Astronomical UnionFlorianópolis, 2013)
In studies of the dynamics of the Galactic disk, such
as the determination of the speed of the spiral pattern
and the permanence of stars in the spiral arms,
it is crucial to know orbits obtained from proper motions, ...

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 ...
The Magellan PFS planet search program: radial velocity and stellar abundance analyses of the 360 au, metal-poor binary "Twins" HD 133131A & B
(2016)
We present a new precision radial velocity (RV) data set that reveals multiple planets orbiting the stars in the similar to 360 au, G2+G2 "twin" binary HD 133131AB. Our six years of high-resolution echelle observations ...
