MAXI/GSC detection of a type-I X-ray burst from RX J1718.4-4029 or a new source
Abstract
The MAXI/GSC nova alert system triggered on a bright X-ray source at 22:05 UT on 2018 August 2. The spectrum of this scan transit was well reproduced by an absorbed blackbody model with a temperature of kT = 1.9 (+0.4, -0.3) keV (90% CL) and the hydrogen column density was 4.8 (-4.3, 7.2)x 1022 cm-2 (90% CL). The averaged X-ray flux in 2 - 10 keV band was 8.6(-1.4,+1.3) x 10-9ergs/cm2/s (90% CL). On the basis of the fitting results, this transient is probably a type-I X-ray burst.
