The Afterglows of Swift-era Gamma-Ray Bursts. I. Comparing pre-Swift and Swift era Long/Soft (Type II) GRB Optical Afterglows
D. A. Kann, S. Klose, B. Zhang +73
We have gathered optical photometry data from the literature on a large sample of Swift-era gamma-ray burst (GRB) afterglows including GRBs up to September 2009, for a total of 76…
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 stellar content of low redshift BL Lac host galaxies from multicolour imaging
T. Hyvonen, J. K. Kotilainen, R. Falomo +2
We present B-band imaging of 18 low redshift (z<0.3) BL Lac objects for which their host galaxies were previously resolved in the R-band and the near-infrared H-band. For a subset…
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…
Multiperiodicity in the newly discovered mid-late Be star V2104 Cygni
K. Uytterhoeven, E. Poretti, E. Rodriguez +5
We obtained the first long, homogenous time-series of V2104Cyg, consisting of 679 datapoints, with the uvbybeta photometers of Sierra Nevada and San Pedro Martir Observatories with…
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…
A giant outburst two years before the core-collapse of a massive star
A. Pastorello, S. J. Smartt, S. Mattila +32
The death of massive stars produces a variety of supernovae, which are linked to the structure of the exploding stars. The detection of several precursor stars of Type II supernova…
The radio delay of the exceptional 3C 454.3 outburst. Follow-up WEBT observations in 2005-2006
M. Villata, C. M. Raiteri, M. F. Aller
In spring 2005 the blazar 3C 454.3 was observed in an unprecedented bright state from the near-IR to the hard X-ray frequencies. A mm outburst peaked in June-July 2005, and it was…
