dc.description.abstractWe present the rst near infra-red spectrum of the faint white dwarf companion HD 114174 B, obtained with Project 1640. Our spectrum, covering the Y, J and H bands, combined with previous TRENDS photometry measurements, allows us to place fur- ther constraints on this companion. We suggest two possible scenarios; either this ob- ject is an old, low mass, cool H atmosphere white dwarf with Te 3800 K or a high mass white dwarf with Te > 6000 K, potentially with an associated cool (Te 700 K) brown dwarf or debris disk resulting in an infra-red excess in the L0 band. We also provide an additional astrometry point for 2014 June 12 and use the modelled companion mass combined with the RV and direct imaging data to place constraints on the orbital parameters for this companion.
