XMM-Newton observations of the low-mass X-ray binary XB1832-330 in the galactic globular cluster NGC 6652
L. Sidoli, N. La Palombara, T. Oosterbroek +1
We report on two XMM-Newton observations performed in 2006 of the luminous low-mass X-ray binary XB1832-330 which is located in the galactic globular cluster NGC 6652 and is probab…
XMM-Newton observation of the persistent Be/neutron-star system X Persei at a high-luminosity level
N. La Palombara, S. Mereghetti
We report on the XMM-Newton observation of the HMXRB X Persei, the prototype of the persistent and low-luminosity Be/neutron star pulsars, which was performed on February 2003. The…
XMM-Newton and ESO observations of the two unidentified gamma-ray sources 3EG J0616-3310 and 3EG J1249-8330
N. La Palombara, R. P. Mignani, E. Hatziminaoglou +3
The limited angular resolution of gamma-ray telescopes prevents a direct identification of the majority of sources detected so far. This is particularly true for the low latitude,…
XMM-Newton observation of the Be/neutron star system RX J0146.9+6121: a soft X-ray excess in a low luminosity accreting pulsar
Nicola La Palombara, Sandro Mereghetti
We report on the XMM-Newton observation of the Be/neutron star X-ray binary system RX J0146.9+6121, a long period (~ 23 m) pulsar in the NGC 663 open cluster. The X-ray luminosity…
A deep XMM-Newton serendipitous survey of a middle-latitude area
G. Novara, N. La Palombara, N. Carangelo +4
The radio quiet neutron star 1E1207.4-5209 has been the target of a 260 ks XMM-Newton observation, which yielded, as a by product, an harvest of about 200 serendipitous X-ray sourc…
Low-energy absorption towards the ultra-compact binary 4U1850-087 located in the globular cluster NGC6712
L. Sidoli, N. La Palombara, T. Oosterbroek +1
We report the results of two XMM-Newton observations of the ultra-compact low-mass X-ray binary 4U1850-087 located in the galactic globular cluster NGC6712. A broad emission featur…
