Optical (top panels) and millimeter (middle panels) light curves for each of the high-eccentricity spectroscopic binaries, as well as separation distances for the binary components as a function of time (bottom panels). Filled dots: R_C-band observations from the Konkoly Schmidt telescope in Hungary; open squares: R_J-band observations from the Teide IAC-80 telescope in Spain; filled stars: 1.25 mm observations with the IRAM 30 m telescope in Spain; arrows: 3σ upper limits for the 1.25 mm fluxes. Note that the millimeter fluxes of UZ Tau E contain an ≈20 mJy contribution from UZ Tau W. A vertical line indicates the time of periastron.
