SISSA Medialab, 2017. https://doi.org/10.22323/1.285.0076.https://doi.org/10.22323/1.285.0076http://hdl.handle.net/11603/2954911th INTEGRAL Conference Gamma-Ray Astrophysics in Multi-Wavelength Perspective, 10-14 October 2016, Amsterdam, The NetherlandsThe Be X-ray binary pulsar EXO 2030+375, first detected in 1985, has shown a significant de- tected X-ray outburst at nearly every periastron passage of its 46-day orbit for the past 25 years, with one low state accompanied by a torque reversal in the 1990s. In early 2015 the outbursts progressively became fainter and less regular while the monotonic spin-up flattened. At the same time a decrease in the Hα line equivalent width was reported, indicating a change in the disk surrounding the mass donor. In order to explore the source behaviour in the poorly explored low-flux state with a possible tran- sition to a state of centrifugal inhibition of accretion we have undertaken an observing campaign with Swift/XRT, NuSTAR and the Nordic Optical Telescope (NOT). This conference contribution reports the preliminary results obtained from our campaign.7 pagesen-USThis work was written as part of one of the author's official duties as an Employee of the United States Government and is therefore a work of the United States Government.
