Espartaco 2, a New Stellar Spectrograph at Universidad de los Andes
We present the construction and early results of ESPARTACO 2, a new stellar spectrograph built for research and education at the Astronomical Observatory of the Universidad de los Andes in Bogotá, Colombia. This instrument offers several resolution modes, from 20,000 in the first order using a 50 $\mu$m fiber, to 100,000 in the second order in the near-infrared. Precise radial-velocity measurements were made possible by simultaneous wavelength calibration. Combined with the 40-cm Meade telescope located at our facilities, a limiting magnitude of 6 was achieved. This instrument represents a significant improvement over its predecessor in terms of throughput, reliability, and ease of use.
