Journal Article
Konopacky, Q. M., Rameau, J., Duchêne, G., Filippazzo, J. C., Giorla Godfrey, P. A., Marois, C., …Wolff, S. G. (2016). Discovery of a Substellar Companion to the Nearby Debris Disk Host HR 2562. Astrophysical Journal Letters, 829(1), Article L4. https://doi.org/10.3847/2041-8205/829/1/l4

We present the discovery of a brown dwarf companion to the debris disk host star HR 2562. This object, discovered with the Gemini Planet Imager (GPI), has a projected separation of 20.3±0.3 au (0.618±0.004") from the star. With the high astrometric p...

Spectroscopic Characterization of HD 95086 b with the Gemini Planet Imager (2016)
Journal Article
De Rosa, R. J., Rameau, J., Patience, J., Graham, J. R., Doyon, R., Lafrenière, D., …Thomas, S. (2016). Spectroscopic Characterization of HD 95086 b with the Gemini Planet Imager. Astrophysical Journal, 824(2), 121-138. https://doi.org/10.3847/0004-637x/824/2/121

We present new H (1.5-1.8 μm) photometric and K1 (1.9-2.2 μm) spectroscopic observations of the young exoplanet HD 95086 b obtained with the Gemini Planet Imager. The H-band magnitude has been significantly improved relative to previous measurements,... Read More about Spectroscopic Characterization of HD 95086 b with the Gemini Planet Imager.

An M-dwarf star in the transition disk of Herbig HD 142527. Physical parameters and orbital elements (2016)
Journal Article
Lacour, S., Biller, B., Cheetham, A., Greenbaum, A., Pearce, T., Marino, S., …Thomas, S. (2016). An M-dwarf star in the transition disk of Herbig HD 142527. Physical parameters and orbital elements. Astronomy & Astrophysics, 590, https://doi.org/10.1051/0004-6361/201527863

Aims. HD 42527A is one of the most studied Herbig Ae/Be stars with a transitional disk, as it has the largest imaged gap in any protoplanetary disk: the gas is cleared from 30 to 90 AU. The HD 142527 system is also unique in that it has a stellar com... Read More about An M-dwarf star in the transition disk of Herbig HD 142527. Physical parameters and orbital elements.

Experience with wavefront sensor and deformable mirror interfaces for wide-field adaptive optics systems (2016)
Journal Article
Basden, A., Atkinson, D., Bharmal, N., Bitenc, U., Brangier, M., Buey, T., …Younger, E. (2016). Experience with wavefront sensor and deformable mirror interfaces for wide-field adaptive optics systems. Monthly Notices of the Royal Astronomical Society, 459(2), 1350-1359. https://doi.org/10.1093/mnras/stw730

Recent advances in adaptive optics (AO) have led to the implementation of wide field-of-view AO systems. A number of wide-field AO systems are also planned for the forthcoming Extremely Large Telescopes. Such systems have multiple wavefront sensors o...

The PDS 66 Circumstellar Disk as Seen in Polarized Light with the Gemini Planet Imager (2016)
Journal Article
Wolff, S. G., Perrin, M., Millar-Blanchaer, M. A., Nielsen, E. L., Wang, J., Cardwell, A., …Wiktorowicz, S. J. (2016). The PDS 66 Circumstellar Disk as Seen in Polarized Light with the Gemini Planet Imager. Astrophysical Journal Letters, 818(1), Article L15. https://doi.org/10.3847/2041-8205/818/1/l15

We present H- and K-band imaging polarimetry for the PDS 66 circumstellar disk obtained during the commissioning of the Gemini Planet Imager (GPI). Polarization images reveal a clear detection of the disk in to the 0farcs12 inner working angle (IWA)...
