We present the results of high-resolution ( R \geq 30,000 ) optical and near-infrared spectroscopic monitoring observations of a FU Orionis-type object , V960 Mon , which underwent an outburst in 2014 November .
We have monitored this object with the Bohyunsan Optical Echelle Spectrograph ( BOES ) and the Immersion GRating INfrared Spectrograph ( IGRINS ) since 2014 December .
Various features produced by a wind , disk , and outflow/jet were detected .
The wind features varied over time and continually weakened after the outburst .
We detected double-peaked line profiles in the optical and near-infrared , and the line widths tend to decrease with increasing wavelength , indicative of Keplerian disk rotation .
The disk features in the optical and near-infrared spectra fit well with G-type and K-type stellar spectra convolved with a kernel to account for the maximum projected disk rotation velocity of about 40.3 \pm 3.8 km s ^ { -1 } and 36.3 \pm 3.9 km s ^ { -1 } , respectively .
We also report the detection of [ \ion S2 ] and H _ { 2 } emission lines , which are jet/outflow tracers and rarely found in FUors .
