Abstract

During the Galactic Plane Scan performed on 2014 January 10, the two JEM-X instruments on-board INTEGRAL detected a type-I X-ray burst from the newly discovered X-ray transient MAXI J1421-613 (ATels #5750, #5751, #5759) over the 5 ks in which the source was in the instruments field of view.

The onset of the burst occurred on 2014 January 10 at 19:05 UTC, and the total event as observed by JEM-X lasted for about 20 s (3-25 keV). The average spectrum of the burst could be roughly described by using a black-body model with temperature kT~1 keV. The corresponding flux was 1.7E-9 erg/cm^2/s (translating into a luminosity of 1.3E37 erg/s at 8 kpc; 3-10 keV). We estimated a persistent flux outside the burst of 7E-10 erg/cm^2/s (3-25 keV).

This detection reveals that MAXI J1421-613 is a newly discovered X-ray bursting transient source, thus hosting an accreting neutron star.
