The Fifth Catalogue of Nearby Stars (CNS5)
The Fifth Catalogue of Nearby Stars (CNS5) aims to provide the most volume-complete sample of stars in the solar neighbourhood. The CNS5 is compiled based on trigonometric... -
Ultracool Dwarf Companion Catalogue UCDC
The Ultracool Dwarf Companion Catalogue consists of 278 multiple systems, 32 of which are newly discovered, each with at least one spectroscopically confirmed Ultracool Dwarf,... -
DwarfArchives.org – Photometry, spectroscopy, and astrometry of L, T, and Y d...
A catalogue of brown dwarfs produced by Gelino et al. The database reflects the state of http://www.dwarfArchives.org on 2015-09-29. -
Ultracool dwarfs in Euclid Deep Fields
The Euclid spacecraft has been launched and will carry out a deep survey benefiting the discovery and characterisation of ultracool dwarfs (UCDs), especially in the Euclid Deep... -
The Gaia ultracool dwarf sample
We identify and investigate known late M, L, and T dwarfs in the Gaia second data release. This sample is being used as a training set in the Gaia data processing chain of the... -
L/T transition BDs from NIR SpeX spectra
We present a technique to identify spectrophotometrically variable L7-T3 brown dwarfs with single-epoch, low-resolution, near-infrared SpeX spectra. We calculated spectral... -
ESO SupJup Survey I. DENIS J0255-4700
It has been proposed that the distinct formation and evolutionary pathways of exoplanets and brown dwarfs may affect the chemical and isotopic content of their atmospheres.... -
Tull RVels, rotation periods and Inclinations
The orientation between a star's spin axis and a planet's orbital plane provides valuable information about the system's formation and dynamical history. For non-transiting... -
Ultracool dwarfs in wide binaries
We present the discovery of 255 binary and 6 multiple system candidates with wide (>5arcsec) separation composed by ultracool dwarfs (UCDs) companions to stars, plus nine... -
Brown dwarf population in NGC 2264
The brown dwarf population in the canonical star-forming region NGC 2264 is so far poorly explored. We present a deep, multiwavelength, multiepoch survey of the star-forming... -
Classification of elusive astronomical objects
The application of machine learning principles in the photometric search of elusive astronomical objects has been a less-explored frontier of research. Here, we have used three... -
Parallaxes of Southern Extremely Cool objects
We present new results from the Parallaxes of Southern Extremely Cool dwarfs program to measure parallaxes, proper motions and multiepoch photometry of L and early T dwarfs. The... -
New L subdwarfs, population properties
We present 27 new L subdwarfs and classify five of them as esdL and 22 as sdL. Our L subdwarf candidates were selected with the UKIRT Infrared Deep Sky Survey and Sloan Digital... -
SHELLQs. XVI. New quasars at 5.8<z<7
We present the spectroscopic discovery of 69 quasars at 5.8<z<7.0, drawn from the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) imaging survey data. This is the... -
BDKP. V. Radial & rot. velocities of M, L, T dwarfs
We report multiepoch radial velocities, rotational velocities, and atmospheric parameters for 37 T-type brown dwarfs observed with Keck/NIRSPEC. Using a Markov Chain Monte Carlo... -
A full-sky census of brown dwarfs within 20pc
We present final Spitzer trigonometric parallaxes for 361 L, T, and Y dwarfs. We combine these with prior studies to build a list of 525 known L, T, and Y dwarfs within 20pc of... -
Parallaxes of late-T and Y dwarfs
We present preliminary trigonometric parallaxes of 184 late-T and Y dwarfs using observations from Spitzer (143), the U.S. Naval Observatory (18), the New Technology Telescope... -
Catalog of M, L, & T dwarfs from PS1 3{pi} Survey
We present a catalog of 9888 M, L and T dwarfs detected in the Pan-STARRS1 3{pi} Survey (PS1), covering three-quarters of the sky. Our catalog contains nearly all known objects... -
H-band polarization around YSOs & BDs
Wide-field near-infrared (NIR) polarimetry was used to examine disk systems around two brown dwarfs (BDs) and two young stellar objects (YSOs) embedded in the Heiles Cloud 2... -
Beyond the local volume. I. HST ultracool dwarfs
Ultracool dwarf stars and brown dwarfs provide a unique probe of large-scale Galactic structure and evolution; however, until recently spectroscopic samples of sufficient size,...
