First disk-resolved spectroscopy of (4) Vesta
Benoît Carry, Pierre Vernazza, Christophe Dumas +1
Vesta, the second largest Main Belt asteroid, will be the first to be explored in 2011 by NASA's Dawn mission. It is a dry, likely differentiated body with spectrum suggesting that…
Generation of radiative knots in a randomly pulsed protostellar jet I. Dynamics and energetics
Rosaria Bonito, Salvatore Orlando, Giovanni Peres +3
HH objects are characterized by a complex knotty morphology detected mainly along the axis of protostellar jets in a wide range of bands. Evidence of interactions between knots for…
A new concept for the combination of optical interferometers and high-resolution spectrographs
S. Albrecht, A. Quirrenbach, R. N. Tubbs +1
The combination of high spatial and spectral resolution in optical astronomy enables new observational approaches to many open problems in stellar and circumstellar astrophysics. H…
Measurement of the Crab nebula polarization at 90 GHz as a calibrator for CMB experiments
J. Aumont, L. Conversi, C. Thum +10
CMB experiments aiming at a precise measurement of the CMB polarization, such as the Planck satellite, need a strong polarized absolute calibrator on the sky to accurately set the…
The cluster Terzan 5 as a remnant of a primordial building block of the Galactic bulge
F. R. Ferraro, E. Dalessandro, A. Mucciarelli +9
Globular star clusters are compact and massive stellar systems old enough to have witnessed the entire history of our Galaxy, the Milky Way. Although recent results suggest that th…
The thermal emission of the young and massive planet CoRoT-2b at 4.5 and 8 microns
M. Gillon, A. A. Lanotte, T. Barman +16
We report measurements of the thermal emission of the young and massive planet CoRoT-2b at 4.5 and 8 microns with the Spitzer Infrared Array Camera (IRAC). Our measured occultation…
