Recent work on jets and disk winds in low-mass X-ray binaries (LMXBs)suggests that they are to a large extent mutually exclusive, with jets observedin spectrally hard states and disk winds observed in spectrally soft states. Inthis paper we use existing literature on jets and disk winds in the luminousneutron star (NS) LMXB GX 13+1, in combination with archival Rossi X-ray TimingExplorer data, to show that this source is likely able to produce jets and diskwinds simultaneously. We find that jets and disk winds occur in the samelocation on the source's track in its X-ray color-color diagram. A furtherstudy of literature on other luminous LMXBs reveals that this behavior is morecommon, with indications for simultaneous jets and disk winds in the black holeLMXBs V404 Cyg and GRS 1915+105 and the NS LMXBs Sco X-1 and Cir X-1. For thethree sources for which we have the necessary spectral information, we findthat the simultaneous jets/winds all occur in their spectrally hardest states.Our findings indicate that in LMXBs with luminosities above a few tens ofpercent of the Eddington luminosity, jets and disk winds are not mutuallyexclusive, and that the presence of disk winds does not necessarily result injet suppression.
