Chemical abundances of late-type pre-main sequence stars in the -Orionis cluster
J. I. González Hernández, J. A. Caballero, R. Rebolo +4
The young -Orionis cluster is an important location for understanding the formation and evolution of stars, brown dwarfs, and planetary-mass objects. Its metallicity, although b…
S Ori J053825.4-024241: A Classical T Tauri-like object at the substellar boundary
J. A. Caballero, E. L. Martín, M. R. Zapatero Osorio +4
We present a spectrophotometric analysis of S Ori J053825.4-024241, a candidate member close to the substellar boundary of the young (1-8 Myr), nearby (~360 pc) sigma Orionis star…
A Methane Isolated Planetary Mass Object in Orion
M. R. Zapatero Osorio, V. J. S. Bejar, E. L. Martin +5
We report on the discovery of a free-floating methane dwarf toward the direction of the young star cluster sigma Orionis. Based on the object's far-red optical and near-infrared ph…
