Primeval very low-mass stars and brown dwarfs - V. A halo L3 subdwarf with prograde eccentric orbit in the Galactic plane
Z. H. Zhang, A. J. Burgasser, L. C. Smith
VVV J125641636202039 is an L subdwarf located in the Galactic plane ( = 0.831 deg) discovered by its high proper motion (1.1 arcsec yr/s). We obtained an optical to near-infr…
Identification of SIPS~J20456332 as a partially resolved binary
Niall R Deacon, Kyle L Sobanja, Leigh C Smith
We show that SIPS J2045-6332, a late M/early L object previously identified as a candidate spectral mix binary, shows an elongated image shape. Using shape measurement techniques o…
Near-IR trigonometric parallaxes of nearby stars in the Galactic plane using the VVV
J. C. Beamin, R. A. Mendez, R. L. Smart +7
We use the multi-epoch K band observations, covering a 5 years baseline to obtain milli and sub-milli arcsec precision astrometry for a sample of eighteen previously…
Probing the Dragonfish star-forming complex: the ionizing population of the young massive cluster Mercer 30
D. de la Fuente, F. Najarro, J. Borissova +11
The Dragonfish Nebula has been recently claimed to be powered by a superluminous but elusive OB association. Instead, systematic searches in near-infrared photometric surveys have…
A large spectroscopic sample of L and T dwarfs from UKIDSS LAS: peculiar objects, binaries, and space density
F. Marocco, H. R. A. Jones, A. C. Day-Jones +7
We present the spectroscopic analysis of a large sample of late-M, L, and T dwarfs from UKIDSS. Using the YJHK photometry from ULAS and the red-optical photometry from SDSS we sele…
49 new T dwarfs identified using methane imaging
C. V. Cardoso, B. Burningham, R. L. Smart +11
We present the discovery of 49 new photometrically classified T dwarfs from the combination of large infrared and optical surveys combined with follow-up TNG photometry. We used mu…
