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…
Direct Spectrum of the Benchmark T dwarf HD 19467 B
Justin R. Crepp, Emily L. Rice, AAron Veicht +18
HD 19467 B is presently the only directly imaged T dwarf companion known to induce a measurable Doppler acceleration around a solar type star. We present spectroscopy measurements…
Mid-Infrared High-Contrast Imaging of HD 114174 B : An Apparent Age Discrepancy in a "Sirius-Like" Binary System
Christopher T. Matthews, Justin R. Crepp, Andrew Skemer +9
We present new observations of the faint "Sirius-like" companion discovered to orbit HD 114174. Previous attempts to image HD 114174 B at mid-infrared wavelengths using NIRC2 at Ke…
