XTE J1701-462 is a neutron-star X-ray transient that was in outburst for nearly 19 months in 2006-2007. For a large part of its outburst the source accreted at super- or near-Eddington luminosities, possibly making it the most luminous neutron-star X-ray transient. Using the VLT, Magellan, and the CTIO 4-m we performed near-infrared spectroscopy and multi-epoch photometry in quiescence to study the properties of the secondary and constrain the binary parameters. The main goal of these observations is to understand what type of donor star powered the exceptionally long and luminous outburst of XTE J1701-462, and to compare its properties with those of the donors in other X-ray binaries. A secondary goal is to search for signatures of ongoing low-level accretion, for which we see evidence in X-rays. Here we report on the first results from our campaign.
