Abstract:
    Atacama Large Millimeter/submillimeter Array (ALMA) observations of
    the high-mass star-forming region G35.20-0.74N have revealed the
    presence of a Keplerian disk in core B rotating about a massive object
    of 18M_☉, as computed from the velocity field. The luminosity of
    such a massive star would be comparable to (or higher than) the
    luminosity of the whole star-forming region. To solve this problem it
    has been proposed that core B could harbor a binary system. This could
    also explain the possible precession of the radio jet associated with
    this core, which has been suggested by its S-shaped morphology.

    We establish the origin of the free-free emission from core B and
    investigate the existence of a binary system at the center of this
    massive core and the possible precession of the radio jet.

    We carried out VLA continuum observations of G35.20-0.74N at 2cm in
    the B configuration and at 1.3cm and 7mm in the A and B
    configurations. The bandwidth at 7mm covers the CH3OH maser line at
    44.069GHz. Continuum images at 6 and 3.6cm in the A configuration
    were obtained from the VLA archive. We also carried out VERA
    observations of the H₂O maser line at 22.235GHz.
