The APOGEE-2 Survey of the Orion Star Forming Complex II: Six-dimensional structure
We present an analysis of spectrosopic and astrometric data from APOGEE-2 and Gaia DR2 to identify structures towards the Orion Complex. By applying a hierarchical clustering algorithm to theExpand

NEAR-INFRARED LINEAR POLARIZATION OF ULTRACOOL DWARFS
We report on near-infrared J- and H-band linear polarimetric photometry of eight ultracool dwarfs (two late-M, five L0-L7.5, and one T2.5) with known evidence for photometric variability due to dustExpand

Close companions around young stars.
Multiplicity is a fundamental property that is set early during stellar lifetimes, and it is a stringent probe of the physics of star formation. The distribution of close companions around youngExpand

New Isolated Planetary-mass Objects and the Stellar and Substellar Mass Function of the σ Orionis Cluster
We report on our analysis of the VISTA Orion ZY JHK{sub s} photometric data (completeness magnitudes of Z = 22.6 and J = 21.0 mag) focusing on a circular area of 2798.4 arcmin{sup 2} around the youngExpand

Optical and Near-infrared Spectra of σ Orionis Isolated Planetary-mass Objects
We have obtained low-resolution optical (0.7-0.98 micron) and near-infrared (1.11-1.34 micron and 0.8-2.5 micron) spectra of twelve isolated planetary-mass candidates (J = 18.2-19.9 mag) of the 3-MyrExpand

Search and characterization of T-type planetary mass candidates in the σ Orionis cluster
We present new photometric and astrometric data available for S Ori 70 and 73, the two T-type planetary-mass member candidates in the σ Orionis cluster (~3 ± 2 Myr, d~360 pc). S Ori 70 ( J ~ 19.9Expand
