The debris disc of solar analogue Τ Ceti : Herschel observations and dynamical simulations of the proposed multiplanet system
(2014-11-01)
Τ Ceti is a nearby, mature G-type star very similar to our Sun, with a massive Kuiper Belt analogue and possible multiplanet system that has been compared to our Solar system. We present Herschel Space Observatory images ...
Near-infrared circular polarization survey in star-forming regions : Correlations and trends
(2014-11-01)
We have conducted a systematic near-infrared circular polarization (CP) survey in star-forming regions, covering high-mass, intermediate-mass, and low-mass young stellar objects. All the observations were made using the ...
The curious case of HD 41248. A pair of static signals buried behind red noise
(2014-10-20)
Gaining a better understanding of the effects of stellar-induced radial velocity noise is critical for the future of exoplanet studies since the discovery of the lowest-mass planets using this method will require us to go ...
A 3D extinction map of the northern Galactic plane based on IPHAS photometry
(2014-10-01)
We present a 3D map of extinction in the northern Galactic plane derived using photometry from the INT/WFC Photometric Hα Survey of the northern Galactic plane. The map has fine angular (~10 arcmin) and distance (100 pc) ...
First release of the IPHAS catalogue of new extended planetary nebulae
(2014-10-01)
We present the first results of our search for new, extended planetary nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the Isaac Newton Telescope Photometric Ha Survey of the Northern ...
The VMC survey - XII : Star cluster candidates in the large magellanic cloud
(2014-10)
In this work we analyse colour-magnitude diagrams (CMDs) of catalogued star clusters located in the Large Magellanic Cloud (LMC), from a YJKs photometric data set obtained by the Visible and Infrared Survey Telescope for ...
Lofar low-band antenna observations of the 3C 295 and boötes fields : Source counts and ultra-steep spectrum sources
(2014-10-01)
We present Low Frequency Array (LOFAR) Low Band observations of the Boötes and 3C 295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy beam-1, making them the deepest images ever obtained ...
High proper motion objects from the UKIDSS Galactic plane survey
(2014-09-21)
The UKIDSS Galactic Plane Survey (GPS) began in 2005 as a seven year effort to survey ~1800 deg2 of the northern Galactic plane in the J, H, and K passbands. The survey included a second epoch of K-band data, with a baseline ...
A relationship between specific star formation rate and metallicity gradient within z ~ 1 galaxies from KMOS-HiZELS
(2014-09-21)
We have observed a sample of typical z ~ 1 star-forming galaxies, selected from the HiZELS survey, with the new K-band Multi-Object Spectrograph (KMOS) near-infrared, multi-integral field unit instrument on the Very Large ...
The Gaia-ESO Survey : Stellar content and elemental abundances in the massive cluster NGC 6705
(2014-09)
Context. Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple populations. Aims. Studying the chemical ...
