Milky Way demographics with the VVV survey III : Evidence for a great dark lane in the 157 million star bulge color-magnitude diagram
(2014-11)
The new generation of IR surveys are revealing and quantifying Galactic features that provide an improved 3D interpretation of our own Galaxy. We present an analysis of the global distribution of dust clouds in the bulge ...
New galactic star clusters discovered in the VVV survey : Candidates projected on the inner disk and bulge
(2014-09)
Context. VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Milky Way bulge and an adjacent ...
GJ 832c : A super-earth in the habitable zone
(2014-08-05)
We report the detection of GJ 832c, a super-Earth orbiting near the inner edge of the habitable zone of GJ 832, an M dwarf previously known to host a Jupiter analog in a nearly circular 9.4 yr orbit. The combination of ...
MOA-2011-BLG-262Lb : A sub-earth-mass moon orbiting a gas giant primary or a high velocity planetary system in the galactic bulge
(2014-04-20)
We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of M host ∼ 4 Jupiter masses hosting a sub-Earth mass moon. The argument for an exomoon ...
Precision radial velocities of 15 M5-M9 dwarfs
(2014-04-11)
We present radial velocity measurements of a sample ofM5V-M9Vstars from our Red-Optical Planet Survey, operating at 0.652-1.025 μm. Radial velocities for 15 stars, with rms precision down to 2.5m-1 over a week-long time-scale, ...
Stellar variability in the VVV survey : Overview and first results
(Cambridge University Press, 2014-03-03)
The Vista Variables in the Vía Láctea (VVV) ESO Public Survey is an ongoing time-series, near-infrared (IR) survey of the Galactic bulge and an adjacent portion of the inner disk, covering 562 square degrees of the sky, ...
