Taking the pulse of the shortest orbital period binary system RX J0806.3+1527
G. L. Israel, S. Covino, S. Dall'Osso +8
RX J0806.3+1527 is thought to be a 321s orbital period (the shortest known) double white dwarf binary system. According to the double degenerate binary (DDB) scenario this source i…
Accurate X-ray position of the Anomalous X-ray Pulsar XTE J1810-197 and identification of its likely IR counterpart
G. L. Israel, N. Rea, V. Mangano +13
We report the accurate sub-arcsec X-ray position of the new Anomalous X-ray Pulsar (AXP) XTE J1810-197, derived with a Chndra-HRC Target of Opportunity observation carried out in N…
A possible new dipping X-ray source in the field of M31
Vanessa Mangano, Gian Luca Israel, Luigi Stella
We report the discovery of the new dipping X-ray source, XMMU J004308.6+411247, in M31, during a systematic search for periodicities in XMM-Newton archival observations. During the…
