The TWA 3 Young Triple System: Orbits, Disks, Evolution
Kendra Kellogg, L. Prato, Guillermo Torres +14
We have characterized the spectroscopic orbit of the TWA 3A binary and provide preliminary families of probable solutions for the TWA 3A visual orbit as well as for the wide TWA 3A…
The Multiplicity of M-Dwarfs in Young Moving Groups
Yutong Shan, Jennifer C. Yee, Brendan P. Bowler +11
We image 104 newly identified low-mass (mostly M-dwarf) pre-main sequence members of nearby young moving groups with Magellan Adaptive Optics (MagAO) and identify 27 binaries with…
Resolving the H-alpha-emitting Region in the Wind of Eta Carinae
Ya-Lin Wu, Nathan Smith, Laird M. Close +2
The massive evolved star Eta Carinae is the most luminous star in the Milky Way and has the highest steady wind mass-loss rate of any known star. Radiative transfer models of the s…
Improving and Assessing Planet Sensitivity of the GPI Exoplanet Survey with a Forward Model Matched Filter
Jean-Baptiste Ruffio, Bruce Macintosh, Jason J. Wang +49
We present a new matched filter algorithm for direct detection of point sources in the immediate vicinity of bright stars. The stellar Point Spread Function (PSF) is first subtract…
Characterizing 51 Eri b from 1-5 m: a partly-cloudy exoplanet
Abhijith Rajan, Julien Rameau, Robert J. De Rosa +58
We present spectro-photometry spanning 1-5 m of 51 Eridani b, a 2-10 M planet discovered by the Gemini Planet Imager Exoplanet Survey. In this study, we present new…
Evidence that the Directly-Imaged Planet HD 131399 Ab is a Background Star
Eric L. Nielsen, Robert J. De Rosa, Julien Rameau +55
We present evidence that the recently discovered, directly-imaged planet HD 131399 Ab is a background star with non-zero proper motion. From new JHK1L' photometry and spectroscopy…
An Optical/near-infrared investigation of HD 100546 b with the Gemini Planet Imager and MagAO
Julien Rameau, Katherine B. Follette, Laurent Pueyo +52
We present H band spectroscopic and Halpha photometric observations of HD 100546 obtained with GPI and MagAO. We detect H band emission at the location of the protoplanet HD 100546…
Complex Spiral Structure in the HD 100546 Transitional Disk as Revealed by GPI and MagAO
Katherine B. Follette, Julien Rameau, Ruobing Dong +53
We present optical and near-infrared high contrast images of the transitional disk HD 100546 taken with the Magellan Adaptive Optics system (MagAO) and the Gemini Planet Imager (GP…
1 to 2.4 micron Near-IR spectrum of the Giant Planet Pictoris b obtained with the Gemini Planet Imager
Jeffrey Chilcote, Laurent Pueyo, Robert J. De Rosa +61
Using the Gemini Planet Imager (GPI) located at Gemini South, we measured the near-infrared (1.0-2.4 micron) spectrum of the planetary companion to the nearby, young star Picto…
On-sky performance analysis of the vector Apodizing Phase Plate coronagraph on MagAO/Clio2
Gilles P. P. L. Otten, Frans Snik, Matthew A. Kenworthy +9
We report on the performance of a vector apodizing phase plate coronagraph that operates over a wavelength range of m and is installed in MagAO/Clio2 at the 6.5 m Magellan C…
An ALMA and MagAO Study of the Substellar Companion GQ Lup B
Ya-Lin Wu, Patrick D. Sheehan, Jared R. Males +6
Multi-wavelength observations provide a complementary view of the formation of young directly-imaged planet-mass companions. We report the ALMA 1.3 mm and Magellan adaptive optics…
