Disc loss and renewal in A0535+26
arXiv:astro-ph/9910367 · doi:10.1046/j.1365-8711.1999.03148.x
Abstract
This paper presents observations of the Be/X-ray binary system A0535+26 revealing the first observed loss of its circumstellar disc, demonstrated by the loss of its JHK infrared excess and optical/IR line emission. However optical/IR spectroscopy reveals the formation of a new inner disc with significant density and emission strength at small radii; the disc has proven to be stable over 5 months in this intermediate state.
