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 ~ 19.9 mag) has a spectral type of T5.5 +/- 1.0 measured from published near-infrared spectra, while no spectroscopic data are available for S Ori 73 (J ~ 21
