The RMS survey : Galactic distribution of massive star formation
(2013-11)
We have used the well-selected sample of~1750 embedded, young, massive stars identified by the Red MSX Source (RMS) survey to investigate the Galactic distribution of recent massive star formation. We present molecular ...
A young hierarchical triple system harbouring a candidate debris disc
(2013-09-11)
We report the detection of a wide young hierarchical triple system where the primary has a candidate debris disc. The primary, TYC 5241-986-1 A, is a known Tycho star which we classify as a late-K star with emission in the ...
Evolution of star formation in the UKIDSS ultra deep survey field-I. Luminosity functions and cosmic star formation rate out to z = 1.6
(2013-07-21)
We present new results on the cosmic star formation history in the Subaru/XMM-Newton Deep Survey (SXDS)-Ultra Deep Survey (UDS) field out to z = 1.6. We compile narrowband data from the Subaru Telescope and the Visible and ...
Two super-earths orbiting the solar analog HD 41248 on the edge of a 7 : 5 mean motion resonance
(2013-07-01)
There are a growing number of multi-planet systems known to be orbiting their host stars with orbital periods that place them in mean motion resonances (MMRs). These systems are generally in first-order resonances and ...
Direct imaging of long period radial velocity targets with NICI
(2013-06-30)
We are finally entering an era where radial velocity and direct imaging parameter spaces are starting to overlap. Radial velocity measurements provide us with a minimum mass for an orbiting companion (the mass as a function ...
A planetary system with gas giants and super-Earths around the nearby M dwarf GJ676A : Optimizing data analysis techniques for the detection of multi-planetary systems
(2012-12-01)
Context. Several M dwarfs are targets of systematical monitoring in searches for Doppler signals caused by low-mass exoplanet companions. As a result, an emerging population of high-multiplicity planetary systems around ...
Astrometric and photometric initial mass functions from the UKIDSS Galactic Clusters Survey - II. The Alpha Persei open cluster
(2012-11-11)
We present the results of a deep (J = 19.1mag) infrared (ZYJHK) survey over the full α Per open cluster extracted from the Data Release 9 of the United Kingdom Infrared Telescope Infrared Deep Sky Survey Galactic Clusters ...
Astrometric and photometric initial mass functions from the UKIDSS Galactic Clusters Survey - III. Praesepe
(2012-11-11)
Over the past decades open clusters have been the subject of many studies. Such studies are crucial considering that the universality of the initial mass function is still a subject of current investigations. Praesepe is ...
Evidence for nine planets in the HD 10180 system
(2012-07-01)
Aims. We re-analyse the HARPS radial velocities of HD 10180 and calculate the probabilities of models with differing numbers of periodic signals in the data. We test the significance of the seven signals, corresponding to ...
Astrometric and photometric initial mass functions from the UKIDSS Galactic Clusters Survey - I. The Pleiades
(2012-05-01)
We present the results of a deep wide-field near-infrared survey of the entire Pleiades cluster recently released as part of the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS) Data Release 9 (DR9). ...
