Aims: We look for new regions for the search of substellar objects. Methods: Two circular areas, 45 arcmin-radius each, centred on the young massive star systems Alnilam and Mintaka in the Orion Belt, have been explored. The regions are very young (less than 10 Ma), have low extinction, and are neighbours to sigma Orionis (~3 Ma), a young open cluster very rich in brown dwarfs and planetary-mass objects. We have used Virtual Observatory tools, the astro-photometric Tycho-2, DENIS and 2MASS… 
Stars and brown dwarfs in the σ Orionis cluster
Context. Only a few open clusters are as important for the study of stellar and substellar objects, and their formation and evolution, as the young σ Orionis cluster. However, a complete
Chemical abundances of late-type pre-main sequence stars in the σ Orionis cluster
Context. The young σ Orionis cluster is an important location for studying the formation and evolution of stars, brown dwarfs, and planetary-mass objects. Its metallicity, although it is a
New deep XMM-Newton observations to the west of the σ Orionis cluster
Aims. The objective of this study is to determine the general X-ray properties of the young stars in the external regions of the σ Orionis cluster (τ ∼ 3M a,d ∼ 385 pc) and determine constraints on
Finding the most variable stars in the Orion Belt with the All Sky Automated Survey
We look for high-amplitude variable young stars in the open clusters and associations of the Orion Belt. We use public data from the ASAS-3 Photometric V -band Catalogue of the All Sky Automated
A comprehensive study of NGC 2023 with XMM–Newton and Spitzer
Nearby star-forming regions are ideal laboratories to study high-energy emission of different stellar populations, from very massive stars to brown dwarfs. NGC 2023 is a reflection nebula situated to
The SEEDS High-Contrast Imaging Survey of Exoplanets Around Young Stellar Objects
We present high-contrast observations of 68 young stellar objects (YSOs) that have been explored as part of the Strategic Exploration of Exoplanets and Disks with Subaru (SEEDS) survey on the Subaru
A TGAS/Gaia DR1 parallactic distance to the σ Orionis cluster
With the new Tycho-Gaia Astrometric Solution (TGAS), I derive a new parallactic distance to the young σ Orionis open cluster, which is a cornerstone region for studying the formation and evolution of
Chemically peculiar stars in the orion OB1 association. I. occurrence frequency, spatial distribution, and kinematics
A total of 85 CP stars of various types are identified among 814 members of the OriOB1 association. The fraction of CP stars decreases with age for different cluster subgroups: from 15.1% in the
SPECTROSCOPIC ASSESSMENT OF WISE-BASED YOUNG STELLAR OBJECT SELECTION NEAR λ AND σ ORIONIS
We have conducted a sensitive search down to the hydrogen burning limit for unextincted stars over ∼200 square degrees around Lambda Orionis and 20 square degrees around Sigma Orionis using the
Identification of red high proper-motion objects in Tycho-2 and 2MASS catalogues using Virtual Observatory tools
Aims. With available Virtual Observatory tools, we looked for new M dwarfs in the solar neighbourhood and M giants with high tangential velocities. Methods. From an all-sky cross-match between the
