Query: Infrared synchrotron oscillations in GRS 1915+105   We report simultaneous observations of the black hole candidate X-ray
transient GRS 1915+105 in the infrared at K and in the radio at 2 cm.
Oscillations of period 26 min were observed in both wavebands, having
(dereddened) peak--peak amplitudes of about 40 mJy and with the IR leading the
radio by 7 min, or perhaps by 33 or 59 min. A synchrotron origin for the
oscillations continues to seem very likely. We consider a range of problems
raised by these observations, and briefly discuss the applicability of
expanding-synchrotron source or conical jet models to the oscillations.
Comparing simplistic estimates of the ejecta mass to the missing inner disc
mass in the model of Belloni et al., we find that a significant fraction of the
inner disc may be ejected during the oscillations.
