Are WC9 Wolf-Rayet stars in colliding-wind binaries?
P. M. Williams, K. A. van der Hucht, G. Rauw
We present results from a spectroscopic search for massive companions to dust-making Galactic WC9 stars as a step to testing the paradigm that dust formation in these systems requi…
Methanol emission from low mass protostars
S. Maret, C. Ceccarelli, A. G. G. M. Tielens +5
We present observations of methanol lines in a sample of Class 0 low mass protostars. Using a 1-D radiative transfer model, we derive the abundances in the envelopes. In two source…
The temperature structure in the core of Sersic 159-03
J. de Plaa, J. S. Kaastra, M. Mendez +6
We present results from a new 120 ks XMM-Newton observation of the cluster of galaxies Sersic 159-03. In this paper we focus on the high-resolution X-ray spectra obtained with the…
The distribution of kHz QPO frequencies in Sco X-1
Tomaso Belloni, Mariano Mendez, Jeroen Homan
The frequencies of kHz Quasi-Periodic Oscillations in the bright Low-Mass X-ray Binary Sco X-1 have been reported to appear preferentially in a 3:2 ratio. We show that a proper sta…
Prompt and afterglow X-ray emission from the X-Ray Flash of 2002 April 27
L. Amati, F. Frontera, J. J. M. in 't Zand +15
We report on the X-ray observations of the X-ray flash (XRF) which occurred on 2002 April 27, three days before BeppoSAX was switched off. The event was detected with the BeppoSAX…
A BeppoSAX-WFC viewpoint of new INTEGRAL sources, particularly IGR J17544-2619
Jean in 't Zand, John Heise, Pietro Ubertini +2
Of the 21 new sources that INTEGRAL discovered up to Feb. 1, 2004, five were detected with the BeppoSAX Wide Field Cameras at earlier times. IGR J16320-4751 appears to be a persist…
