The neutron star LMXB transient 4U 1608-52 is evolving towards the hard state
Abstract
The neutron star LMXB transient 4U 1608-52 has started an outburst since 2014-01-16 UT (MJD 56673) when it soon entered into the soft state as seen in its hardness ratio between the BAT (15-50 keV) and MAXI (2-10 keV) intensities in Crab units, according to the distributions of the hardness ratio of the hard state and/or the soft state (see Yu & Yan 2009, ApJ, 701, 1940).
