Detection of exocometary CO within the 440 Myr-old Fomalhaut belt: a similar CO+CO ice abundance in exocomets and Solar System comets

L. Matrà, M. A. MacGregor, P. Kalas +13

Recent ALMA observations present mounting evidence for the presence of exocometary gas released within Kuiper belt analogues around nearby main sequence stars. This represents a un…

A Complete ALMA Map of the Fomalhaut Debris Disk

Meredith A. MacGregor, Luca Matra, Paul Kalas +14

We present ALMA mosaic observations at 1.3 mm (223 GHz) of the Fomalhaut system with a sensitivity of 14 Jy/beam. These observations provide the first millimeter map of the cont…

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…

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…
