Description
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 that reached peak luminosities comparable to the
Eddington- limit. This makes 2S 1803-245 one of the thermally brightest
NSs in quiescence according to the cooling theory, and therefore one of
the best quiescent NSs to investigate. Furthermore, EXO 1745-248 showed
enhanced cooling and its quiescent spectrum was completely dominated by
a power-law tail, suggested to be related to a high magnetic field
strength NS (as is also suggested in the brightest NS/LMXBs). This makes
2S 1803-245 an excellent candidate to verify the connection between high
magnetic field strength NS and the high peak luminosity during outburst.
