It is difficult for intermediate-mass X-ray binaries to form compact intermediate-mass binary pulsars (IMBPs) with a short orbital-period ( ≲ 3 d), which have heavy ( ≳ 0.4 M ⊙) CO or ONeMg white dwarf (WD) companions.Since neutron star + He star binaries may experience common-envelope evolution, they have some advantage to … SpletSuch objects are intermediate in mass between stars and planets and have been given the name brown dwarfs ( Figure 18.8 ).
