Coronagraphic phase diversity: a simple focal plane sensor for high-contrast imaging
, 2012 International audienceExoplanet direct imaging is a challenging goal of today's astronomical instrumentation. Several high-contrast imaging instruments dedicated to this task are currently being integrated; they are ultimately limited by the presence of ...

Coronagraphic imaging on the VLTI with VIDA
, 2004 In a few years, the VLTI will be able to combine light from 4 to 8 telescopes equipped with adaptive optics. In order to exploit the full VLTI infrastructure, a second generation instrument, based on the densified pupil concept (VIDA), has been proposed ...

On Some Properties of SEP Effective CMEs
International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011 Solar energetic particles (SEP) are believed to originate from two different sources, solar flares and coronal mass ejections (CMEs). The large SEP events constitute a serious radiation hazard. The high‐energy solar proton data obtained from NOAA Space Environment Services Center are used to investigate some statistical properties such as speed ...

Probing the Outskirts of M Dwarf Planetary Systems with a Cycle 1 JWST NIRCam Coronagraphy Survey
The Astronomical JournalThe population of giant planets on wide orbits around low-mass M dwarf stars is poorly understood, but the unprecedented sensitivity of JWST NIRCam coronagraphic imaging now provides direct access to planets significantly less massive than Jupiter beyond
