Two spectral states of the transient X-ray burster SAX J1747.0-2853
L. Natalucci, A. Bazzano, M. Cocchi +4
The neutron star binary SAX J1747.0-2853, located in the Galactic Center region at about 0.5 deg from Sgr A* and at a distance of 9 kpc, has been observed in outburst four times (1…
Magnetic field generation in relativistic shocks
Jorrit Wiersma, A. Achterberg
We present an analytical estimate for the magnetic field strength generated by the Weibel instability in ultra-relativistic shocks in a hydrogen plasma. We find that the Weibel ins…
GBT Discovery of Two Binary Millisecond Pulsars in the Globular Cluster M30
Scott M. Ransom, Ingrid H. Stairs, Donald C. Backer +4
We report the discovery of two binary millisecond pulsars in the core-collapsed globular cluster M30 using the Green Bank Telescope (GBT) at 20 cm. PSR J2140-2310A (M30A) is an ecl…
The dynamical mass of the young cluster W3 in NGC 7252: Heavy-Weight globular cluster or ultra compact dwarf galaxy ?
C. Maraston, N. Bastian, R. P. Saglia +3
We have determined the dynamical mass of the most luminous stellar cluster known to date, i.e. object W3 in the merger remnant galaxy NGC 7252. The dynamical mass is estimated from…
A Chandra observation of the old open cluster M67
Maureen van den Berg, Gianpiero Tagliaferri, Tomaso Belloni +1
We present the results of a 47-ks Chandra-ACIS observation of the old open cluster M67. We detected 25 proper-motion cluster members (including ten new sources) and 12 sources (all…
Magnetic field decay, or just period-dependent beaming?
Joeri van Leeuwen, Frank Verbunt
Several recent papers conclude that radio-pulsar magnetic fields decay on a time-scale of 10 Myr, apparently contradicting earlier results. We have implemented the methods of these…
