A coronagraph is a telescopic attachment designed to block out the direct light from a star or other bright object so that nearby objects – which otherwise...

A vortex coronagraph is a type of optical instrument for telescopes that blocks out the glare of bright objects (like stars) so that smaller objects near...

Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory satellite (SOHO) consists of three solar coronagraphs with nested fields...

the use of the NRO telescopes. The Roman baseline design includes a coronagraph to enable the direct imaging of exoplanets. Several implementations of...

LUVOIR would be equipped with an internal coronagraph instrument, called ECLIPS for Extreme Coronagraph for LIving Planetary Systems, to enable direct...

stars than conventional Lyot type coronagraph designs. For example, at a distance of 100 pc, the PIAA coronagraph on SCExAO would be able to image from...

Emission Line Coronagraph (VELC) is a key instrument on the Aditya spacecraft. The VELC is an internally occulted reflective coronagraph designed to fulfil...

However, the estimated mass values for CMEs are only lower limits, because coronagraph measurements provide only two-dimensional data. CMEs erupt from strongly...
