Aims. We aim at determining the rotational periods and the starspot properties in very young low-mass stars belonging to the Ori OB1c star forming region, contributing to the study of the angular momentum and magnetic activity evolution in these objects. Methods. We performed an intensive photometric monitoring of the PMS stars falling in a field of about 10 0 � 10 0 in the vicinity of the Orion Nebula Cluster (ONC), also containing the BD eclipsing system 2MASSJ05352184-0546085. Photometric… 
A spectroscopic survey of the youngest field stars in the solar neighbourhood
Aims. We present the first results of an ambitious ground-based observation programme conducted on 1–4 m class telescopes. Our sample consists of 1097 active and presumably young stars, all of them
A Spectroscopic Survey of the Youngest Field Stars in the Solar Neighborhood. II. The optically faint sample
Star formation in the solar neighborhood is mainly traced by young stars in open clusters, associations and in the field, which can be identified by their X-ray emission. The determination of stellar
Precision Photometric Monitoring of Very Low Mass σ Orionis Cluster Members: Variability and Rotation at a Few Myr
We present high-precision photometry on 107 variable low-mass stars and brown dwarfs in the ~3 Myr σ Orionis open cluster. We have carried out I-band photometric monitoring within two fields,
Spots, Flares, Accretion, and Obscuration in the Pre-main-sequence Binary DQ Tau
DQ Tau is a young low-mass spectroscopic binary, consisting of two almost equal-mass stars on a 15.8 d period surrounded by a circumbinary disk. Here, we analyze DQ Tau's light curves obtained by
Magnetic activity and differential rotation in the very young star KIC 8429280
Aims. We present a spectroscopic and photometric analysis of the rapid rotator KIC 8429280, discovered by ourselves as a very young star and observed by the NASA Kepler mission, designed to determine
A test field for Gaia. Radial velocity catalogue of stars in the South Ecliptic Pole
Gaia is a space mission currently measuring the five astrometric parameters as well as spectrophotometry of at least 1 billion stars to G = 20.7 mag with unprecedented precision. The sixth parameter
CSI 2264: Simultaneous optical and infrared light curves of young disk-bearing stars in NGC 2264 with CoRoT and Spitzer-- evidence for multiple origins of variability
We present the Coordinated Synoptic Investigation of NGC 2264, a continuous 30 day multi-wavelength photometric monitoring campaign on more than 1000 young cluster members using 16 telescopes. The
Stellar Rotation of T Tauri Stars in the Orion Star-forming Complex
We present a large-scale study of stellar rotation for T Tauri stars in the Orion star-forming complex. We use the projected rotational velocity ( vsin(i) ) estimations reported by the APOGEE-2
High-level magnetic activity nature of the eclipsing binary KIC 12418816
We present comprehensive spectroscopic and photometric analysis of the detached eclipsing binary KIC 12418816, which is composed of two very similar and young main sequence stars of spectral type K0
Discovery of new members of the nearby young stellar association in Cepheus
Young field stars are hardly distinguishable from older ones because their space motion rapidly mixes them with the stellar population of the Galactic plane. Nevertheless, a careful target selection


Rotational periods of solar-mass young stars in Orion
Context. The evolution of the angular momentum in young low-mass stars is still a debated issue. The stars presented here were discovered as X-ray sources in the ROSAT All-Sky Survey (RASS) of the
Stellar rotation and variability in the Orion Nebula Cluster
A wide field imager attached to the MPG/ESO 2.2 m telescope on La Silla has been used to monitor the Orion Nebula Cluster on 45 nights between 25 Dec. 1998 and 28 Feb. 1999. Ninety-two images were
Near-Infrared Photometric Variability of Stars toward the Orion A Molecular Cloud
We present an analysis of J, H, and K_s time-series photometry obtained with the southern 2MASS telescope over a 0.°84 × 6° region centered near the Trapezium region of the Orion Nebula cluster.
The Rotation of Low-Mass Pre-Main-Sequence Stars (Invited Review)
Major photometric monitoring campaigns of star-forming regions in the past decade have provided rich rotation period distributions of pre-main-sequence stars. The rotation periods span more than an
Rotation and variability of very low mass stars and brown dwarfs near epsilon Ori
We explore the rotation and activity of very low mass (VLM) objects by means of a photometric variability study. Our targets in the vicinity of ϵ  Ori belong to the Ori OB1b population in the Orion
A Correlation between Pre-Main-Sequence Stellar Rotation Rates and IRAC Excesses in Orion
Early observations of T Tauri stars suggested that stars with evidence of circumstellar accretion disks rotated slower than stars without such evidence, but more recent results are not as clear.
Rotation and accretion of very low mass objects in the sigma Ori cluster
We report on two photometric monitoring campaigns of Very Low Mass (VLM) objects in the young open cluster around σ Orionis. Our targets were pre-selected with multi-filter photometry in a field of
