Following the widespread practice of exoplanetary transit simulations, various presumed components of an extrasolar system can be examined in numerically simulated transits, including exomoons, rings around planets, and the deformation […]

Hunting For Exocomet Transits In The TESS Database Using The Random Forest Method
This study introduces an approach to detecting exocomet transits in the dataset of the Transiting Exoplanet Survey Satellite (TESS), specifically within its Sector 1. Given the limited number of exocomet […]

Curves Of Growth For Transiting Exocomets: Application To Fe II Lines In The Beta Pictoris System
This study introduces the exocomet curve of growth, a new method to analyse the variable absorptions observed in β Pictoris spectrum and link them to the physical properties of the […]

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).

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 […]

Exocomets Size Distribution In The β Pictoris Planetary System
The star β Pictoris harbors a young planetary system, which is characterized by the presence of a gaseous and dusty debris disk, at least two massive planets and many minor […]

Inferring Late Stage Enrichment of Exoplanet Atmospheres from Observed Interstellar Comets
The discovery of the first two interstellar comets implies that, on average, every star contributes a substantial amount of material to the galactic population by ejecting such bodies from the […]
