EChO - Exoplanet Characterisation Observatory
G. Tinetti, J. P. Beaulieu, T. Henning +131
A dedicated mission to investigate exoplanetary atmospheres represents a major milestone in our quest to understand our place in the universe by placing our Solar System in context…
VVV High Proper Motion Survey
M. Gromadzki, R. Kurtev, S. Folkes +7
Here we present survey of proper motion stars towards the Galactic Bulge and an adjacent plane region base on VISTA-VVV data. The searching method based on cross-matching photometr…
Analysis of combined radial velocities and activity of BD+20 1790: evidence supporting the existence of a planetary companion
M. Hernán-Obispo, M. Tuomi, M. C. Gálvez-Ortiz +17
This paper presents the simultaneous Bayesian analysis of the radial velocity and activity indices for the K5Ve active star BD+20 1790, that was proposed to host a close-in massive…
A 1500 deg Near Infrared Proper Motion Catalogue from the UKIDSS Large Area Survey
L. Smith, P. W. Lucas, B. Burningham +5
The UKIDSS Large Area Survey (LAS) began in 2005, with the start of the UKIDSS program as a 7 year effort to survey roughly 4000 deg at high galactic latitudes in Y, J, H and K…
NPARSEC: NTT Parallaxes of Southern Extremely Cool objects. Goals, targets, procedures and first results
R. L. Smart, C. G. Tinney, B. Bucciarelli +21
The discovery and subsequent detailed study of T dwarfs has provided many surprises and pushed the physics and modeling of cool atmospheres in unpredicted directions. Distance is a…
ROPS: A New Search for Habitable Earths in the Southern Sky
J. R. Barnes, J. S. Jenkins, H. R. A. Jones +7
We present the first results from our Red Optical Planet Survey (ROPS) to search for low mass planets orbiting late type dwarfs (M5.5V - M9V) in their habitable zones (HZ). Our obs…
The distance to the cool T9 brown dwarf ULAS J003402.77-005206.7
R. L. Smart, H. R. A. Jones, M. G. Lattanzi +8
Aims. We demonstrate the feasibility of determining parallaxes for nearby objects with theWide Field Camera on the United Kingdom Infrared Telescope (UKIRT) using the UKIRT Infrare…
A sensitivity analysis of the WFCAM Transit Survey for short-period giant planets around M dwarfs
Gábor Kovács, S. Hodgkin, B. SipÅcz +11
The WFCAM Transit Survey (WTS) is a near-infrared transit survey running on the United Kingdom Infrared Telescope (UKIRT), designed to discover planets around M dwarfs. The WTS act…
First T dwarfs in the VISTA Hemisphere Survey
N. Lodieu, B. Burningham, A. Day-Jones +21
The aim of the project is to improve our current knowledge of the density of T dwarfs and the shape of the substellar initial mass function by identifying a magnitude-limited sampl…
Using SPICA Space Telescope to characterize Exoplanets
J. R. Goicoechea, B. Swinyard, G. Tinetti +26
We present the 3.5m SPICA space telescope, a proposed Japanese-led JAXA-ESA mission scheduled for launch around 2017. The actively cooled (<5 K), single aperture telescope and mono…
Diversity among other worlds: characterization of exoplanets by direct detection
J. Schneider, A. Boccaletti, A. Aylward +34
The physical characterization of exoplanets will require to take spectra at several orbital positions. For that purpose, a direct imaging capability is necessary. Direct imaging re…
Precision radial velocities of 15 M5 - M9 dwarfs
J. R. Barnes, J. S. Jenkins, H. R. A. Jones +8
We present radial velocity measurements of a sample of M5V-M9V stars from our Red-Optical Planet Survey, ROPS, operating at 0.65-1.025 micron. Radial velocities for 15 stars, with…
Parallaxes and Infrared Photometry of three Y0 dwarfs
R. L. Smart, Dániel Apai, J. Davy Kirkpatrick +7
We have followed up the three Y0 dwarfs WISEPA J041022.71+150248.5, WISEPA J173835.53+273258.9 and WISEPC J205628.90+145953.3 using the UKIRT/WFCAM telescope/instruments. We find p…
Search for the coolest white dwarfs in the Galaxy
S. Catalan, R. Napiwotzki, S. Hodgkin +2
A number of so-called ultra-cool white dwarfs have been detected in different surveys so far. However, based on anecdotal evidence it is believed that most or all of these ultra-co…
