We present the results of two XMM-Newton observations of Jupiter carried out in 2003 for 100 and 250 ks (or 3 and 7 planet rotations) respectively. X-ray images...

Recently, a new class of type I X-ray bursters was suggested, the ``burst-only sources'', i.e. detected only during an X-ray burst, and no persistent emission...

We propose to observe the peculiar neutron star low mass X-ray binary (NS/LMXB) 2S 1803-245 in quiescence. Together with EXO 1745-248, it is the only transient...

X-ray sources at intermediate fluxes (a few x10-14erg/cm a sky density of ~100deg-2 are responsible for a significant fraction of the cosmic X-ray background at...

An XMM-Newton target of opportunity observation of the field around the transient pulsar XTE J0055-727 (ATEL #214) in the Small Magellanic Cloud was performed...

We report optical spectroscopy of LSPM J1528+5937, the proposed optical counterpart to the recently discovered X-ray transient XMMSL1 J152835.4+593754 (Saxton...

Orbital properties of hot Jupiters depend on the temperature and rotation rate of their host stars. These observed correlations provide some of the very few...
