A low-mass triple system with a wide L/T transition brown dwarf component: NLTT 51469AB/SDSS 2131-0119
B. Gauza, V. J. S. Béjar, A. Pérez-Garrido +6
We demonstrate that the previously identified L/T transition brown dwarf SDSS J213154.43-011939.3 (SDSS 2131-0119) is a widely separated (82.3'', 3830 au) common proper motio…
Parallaxes of southern extremely cool objects III: 118 L \& T dwarfs
R. L. Smart, B. Bucciarelli, H. R. A. Jones +17
We present new results from the Parallaxes of Southern Extremely Cool dwarfs program to measure parallaxes, proper motions and multi-epoch photometry of L and early T dwarfs. The o…
SPECIES I: Spectroscopic Parameters and atmosphEric ChemIstriEs of Stars
M. G. Soto, J. S. Jenkins
The detection and subsequent characterisation of exoplanets are intimately linked to the characteristics of their host star. Therefore, it is necessary to study the star in detail…
Surprisingly different starspot distributions on the near equal-mass equal-rotation-rate stars in the M dwarf binary GJ 65 AB
J. R. Barnes, S. V. Jeffers, C. A. Haswell +4
We aim to understand how stellar parameters such as mass and rotation impact the distribution of starspots on the stellar surface. To this purpose, we have used Doppler imaging to…
Recovering planet radial velocity signals in the presence of starspot activity in fully convective stars
J. R. Barnes, S. V. Jeffers, G. Anglada-Escude +6
Accounting for stellar activity is a crucial component of the search for ever-smaller planets orbiting stars of all spectral types. We use Doppler imaging methods to demonstrate th…
New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems
P. Bluhm, M. I. Jones, L. Vanzi +10
We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orb…
Blue not brown: UKIDSS T dwarfs with suppressed K-band flux
D. N. Murray, B. Burningham, H. R. A Jones +13
We have used blue near-infrared colours to select a group of 12 spectroscopically-confirmed UKIDSS T dwarfs later than T4. From amongst these we identify the first two kinematic ha…
NACO-SDI imaging of known companion host stars from the AAPS and Keck planet search surveys
J. S. Jenkins, H. R. A. Jones, B. Biller +8
Direct imaging of brown dwarfs as companions to solar-type stars can provide a wealth of well-constrained data to "benchmark" the physics of such objects, since quantities like met…
A long-period planet orbiting a nearby Sun-like star
Hugh R. A. Jones, R. Paul Butler, C. G. Tinney +10
The Doppler wobble induced by the extra-solar planet HD 134987b was first detected by data from the Keck Telescope nearly a decade ago, and was subsequently confirmed by data from…
