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…

Project 1640 Observations of Brown Dwarf GJ 758 B: Near-Infrared Spectrum and Atmospheric Modeling

R. Nilsson, A. Veicht, P. A. Giorla Godfrey +23

The nearby Sun-like star GJ 758 hosts a cold substellar companion, GJ 758 B, at a projected separation of 30 AU, previously detected in high-contrast multi-band photometr…

Characterization of the Companion to Her

Lewis C. Roberts, Brian D. Mason, Jonathan Aguilar +24

Her is a nearby quadruple system with a G-subgiant primary and several low mass companions arranged in a 2+2 architecture. While the BC components have been well characterized,…

Spectral Typing of Late Type Stellar Companions to Young Stars from Low Dispersion Near-Infrared Integral Field Unit Data

Lewis C. Roberts, Emily L. Rice, Charles A. Beichman +22

We used the Project 1640 near-infrared coronagraph and integral field spectrograph to observe 19 young solar type stars. Five of these stars are known binary stars and we detected…
