Project 1640 Observations of the White Dwarf HD 114174 B

E. Bacchus, I. R. Parry, R. Oppenheimer +24

We present the first 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…

Reconnaissance of the HR 8799 Exosolar System II: Astrometry and Orbital Motion

L. Pueyo, R. Soummer, J. Hoffmann +30

We present an analysis of the orbital motion of the four sub-stellar objects orbiting HR8799. Our study relies on the published astrometric history of this system augmented with an…
