New SWIFT X-ray transient in the SMC: A new Be/X-ray binary?
Abstract
We report the detection of a transient source with SWIFT during the SMC survey (PI Immler). The source was detected in two observations on 2011-08-20 from 02:19 to 18:28 (UT) and 2011-08-21 from 00:45 to 04:06 with 1909 s and 1337 s exposure, respectively. The count rate increased from (0.027 ± 0.004) cts/s to (0.036 ± 0.006) cts/s. The positions (J2000) are RA = 00 52 00 DEC = -73 29 25.3 and RA = 00 52 01 DEC = -73 29 20, respectively, with relatively large statistical errors of ~4.8 arcsec due to large off-axis angles.
