JWST-TST High Contrast: Asymmetries, Dust Populations And Hints Of A Collision In The β Pictoris Disk With NIRCam And MIRI
We present the first JWST MIRI and NIRCam observations of the prominent debris disk around Beta Pictoris. Coronagraphic observations in 8 filters spanning from 1.8 to 23~μm provide an unprecedentedly […]

Webb Telescope Discovers Dusty ‘Cat’s Tail’ In The Beta Pictoris System
Beta Pictoris, a young planetary system located just 63 light-years away, continues to intrigue scientists even after decades of in-depth study.

Dynamics Of The Beta Pictoris Planetary System And Its Falling Evaporating Bodies
For decades, the spectral variations of Beta Pictoris have been modelled as the result of the evaporation of exocomets close to the star, termed falling evaporating bodies (FEBs).

Has The Dust Clump In The Debris Disk of Beta Pictoris Moved?
The edge-on debris disk of the nearby young star Beta Pictoris shows an unusual brightness asymmetry in the form of a clump.

Imaging Of Exocomets With Infrared Interferometry
Active comets have been detected in several exoplanetary systems, although so far only indirectly, when the dust or gas in the extended coma has transited in front of the stellar […]

Likelihood Ratio Map For Direct Exoplanet Detection
Direct imaging of exoplanets is a challenging task due to the small angular distance and high contrast relative to their host star, and the presence of quasi-static noise.
