The Scuti pulsations of Pictoris as observed by ASTEP from Antarctica
D. Mékarnia, E. Chapellier, T. Guillot +13
The Antartica Search for Transiting Extrasolar Planets (ASTEP), an automatized 400 mm telescope located at Concordia station in Antarctica, monitored beta Pictoris continuously to…
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…
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…
