Multiple protostellar systems. II. A high resolution near-infrared imaging survey in nearby star-forming regions
G. Duchêne, S. Bontemps, J. Bouvier +3
(abridged) Our project endeavors to obtain a robust view of multiplicity among embedded Class I and Flat Spectrum protostars in a wide array of nearby molecular clouds to disentang…
First Stars VIII -- Enrichment of the neutron-capture elements in the early Galaxy
P. Francois, E. Depagne, V. Hill +12
Our aim is to measure accurate, homogeneous neutron-capture element abundances for the sample of 32 EMP giant stars studied earlier in this series, including 22 stars with [Fe/H] $…
The WEBT Campaign on the Blazar 3C279 in 2006
M. Boettcher
The quasar 3C279 was the target of an extensive multiwavelength monitoring campaign from January through April 2006, including an optical-IR-radio monitoring campaign by the Whole…
GRB 060206 and the quandary of achromatic breaks in afterglow light curves
P. A. Curran, A. J. van der Horst, R. A. M. J. Wijers +20
Gamma-ray burst afterglow observations in the Swift era have a perceived lack of achromatic jet breaks compared to the BeppoSAX era. We present our multi-wavelength analysis of GRB…
The Geneva-Copenhagen Survey of the Solar neighbourhood II. New uvby calibrations and rediscussion of stellar ages, the G dwarf problem, age-metallicity diagram, and heating mechanisms of the disk
J. Holmberg, B. Nordstrom, J. Andersen
Ages, metallicities, space velocities, and Galactic orbits of stars in the Solar neighbourhood are fundamental observational constraints on models of galactic disk evolution. We ai…
Photospheric and chromospheric activity on EY Dra
H. Korhonen, K. Brogaard, K. Holhjem +4
Magnetic activity in the photosphere and chromosphere of the M dwarf EY Dra is studied and possible correlations between the two are investigated using photometric observations in…
