H.E.S.S. observations of the supernova remnant RX J0852.0-4622: shell-type morphology and spectrum of a widely extended VHE gamma-ray source
HESS Collaboration, F. A. Aharonian
The shell-type supernova remnant RX J0852.0-4622 was observed with the High Energy Stereoscopic System (H.E.S.S.) of Atmospheric Cherenkov Telescopes between December 2004 and May…
A highly-collimated SiO jet in the HH212 protostellar outflow
C. Codella, S. Cabrit, F. Gueth +4
We mapped the HH212 Class 0 outflow in SiO(2--1, 5--4) and continuum using the PdBI in its extended configurations. The unprecedented angular resolution (down to 0.34") allows accu…
Probing Protoplanetary Disks with Silicate Emission: Where is the silicate emission zone?
J. E. Kessler-Silacci, C. P. Dullemond, J. -C. Augereau +6
Recent results indicate that the grain size and crystallinity inferred from observations of silicate features may be correlated with spectral type of the central star and/or disk g…
Physical Orbit for Lambda Virginis and a Test of Stellar Evolution Models
M. Zhao, J. D. Monnier, G. Torres +12
Lambda Virginis (LamVir) is a well-known double-lined spectroscopic Am binary with the interesting property that both stars are very similar in abundance but one is sharp-lined and…
Testing Gaussianity on Archeops Data
A. Curto, J. Aumont, J. F. Macias-Perez +5
A Gaussianity analysis using a goodness-of-fit test and the Minkowski functionals on the sphere has been performed to study the measured Archeops Cosmic Microwave Background (CMB)…
The JCMT Spectral Legacy Survey
R. Plume, G. A. Fuller, F. Helmich +30
Stars form in the densest, coldest, most quiescent regions of molecular clouds. Molecules provide the only probes which can reveal the dynamics, physics, chemistry and evolution of…
Primary particle acceleration above 100 TeV in the shell-type Supernova Remnant RX J1713.7-3946 with deep H.E.S.S. observations
The HESS Collaboration, F. Aharonian
We present deep H.E.S.S. observations of the supernova remnant (SNR) RX J1713.7-3946. Combining data of three years - from 2003 to 2005 - we obtain significantly increased statisti…
Magnetospheric accretion-ejection processes in the classical T Tauri star AA
J. Bouvier, S. H. P. Alencar, T. Boutelier +8
From a long time series of high resolution (R=115,000) HARPS spectra and simultaneous broad-band photometry, we report new evidence for magnetospheric accretion as well as ejection…
The origin of the strong soft excess and puzzling iron line complex in Mkn 841
P. O. Petrucci, G. Ponti, G. Matt +8
Mkn 841 has been observed during 3 different periods (January 2001, January 2005 and July 2005) by XMM-Newton for a total cumulated exposure time of ~108 ks. We present in this pap…
A unified paradigm for the spectral and temporal evolution of Black Hole X-ray Binaries
P. O. Petrucci, J. Ferreira, C. Cabanac +2
We present a unified picture to explain the spectral states of BH binaries based on the two-flow model. In our view, the central regions have a multi-flow configuration consisting…
VLTI/AMBER interferometric observations of the recurrent Nova RS Oph 5.5 days after outburst
Olivier Chesneau, N. Nardetto, F. Millour +15
We report on interferometric AMBER/VLTI observations of the recurrent nova RS Oph five days after its outburst on 2006 Feb 12. Using three baselines from 44 to 86m, and a spectral…
An asymmetry detected in the disk of Kappa CMa with the AMBER/VLTI
Anthony Meilland, Florentin Millour, Philippe Stee +7
Aims. We study the geometry and kinematics of the circumstellar environment of the Be star Kappa CMa in the Br gamma emission line and its nearby continuum. Methods. We use the VLT…
The broad band spectrum and variability of NGC 4151 observed by BeppoSAX
A. De Rosa, L. Piro, G. C. Perola +5
We present an analysis of all SAX observations of NGC 4151. This source was observed 5 times from 1996 to 2001 with durations ranging from a day to four days. The intrinsic continu…
The Monitor project: Searching for occultations in young open clusters
Suzanne Aigrain, Simon Hodgkin, Jonathan Irwin +5
The Monitor project is a photometric monitoring survey of nine young (1-200Myr) clusters in the solar neighbourhood to search for eclipses by very low mass stars and brown dwarfs a…
The XMM-Newton Optical Monitor Survey of the Taurus Molecular Cloud
Marc Audard, Kevin Briggs, Nicolas Grosso +4
The Optical Monitor (OM) on-board XMM-Newton obtained optical/ultraviolet data for the XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST), simultaneously with the X-ra…
