MAXI GSC detection of a renewed X-ray activity from Be X-ray binary pulsar XTE J1858+034
Abstract
We report on the renewed X-ray activity of a Be/X-ray binary pulsar, XTE J1858+034 observed with MAXI/GSC. The source flux in 4-10 keV band was 12 ± 5 mCrab in one-day average on 2011 November 6 (MJD 55871), and slowly increased up to 24 ± 5 mCrab on November 15 (MJD 55880). The flux in 2-4 keV has been <10 mCrab at the 1-sigma upper limit for these period, which indicates that the source is moderately absorbed.
