Exocomets size distribution in the [Formula: see text] Pictoris planetary system. [PDF]
Sci Rep, 2022 The star $$\beta$$ β Pictoris harbors a young planetary system of about 20 million years old, which is characterized by the presence of a gaseous and dusty debris disk, at least two massive planets and many minor bodies.

The Origins & Reservoirs of Exocomets [PDF]
Space Science ReviewsSmall bodies exist in distinct populations within their planetary systems. These reservoir populations hold a range of compositions, which to first order are dependent on formation location relative to their star.

Evaporation, from exoplanets to exocomets [PDF]
Comptes Rendus Physique, 2023 Here we review the last advances in our understanding of exoplanetary upper atmospheres, with a focus on the evaporation of exoplanets orbiting close to their stars.

Exocomets: A spectroscopic survey [PDF]
Astronomy and Astrophysics, 2020 Context. While exoplanets are now routinely detected, the detection of small bodies in extrasolar systems remains challenging. Since the discovery of sporadic events, which are interpreted to be exocomets (falling evaporating bodies) around β Pic in the ...

Exocomets from a Solar System Perspective [PDF]
Publications of the Astronomical Society of the Pacific, 2020 Exocomets are small bodies releasing gas and dust which orbit stars other than the Sun. Their existence was first inferred from the detection of variable absorption features in stellar spectra in the late 1980s using spectroscopy.

Imaging of exocomets with infrared interferometry
Astronomy and Astrophysics, 2023 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 disk.

The Appearance and Disappearance of Exocomet Gas Absorption [PDF]
Advances in Astronomy, 2015 CaII K-line (3933 Å) absorption profiles observed towards 15 A-type and two B-type stars with known (or suspected) debris disks, in addition to archival spectral data for three A-type stars, are presented.

CHEOPS’s hunt for exocomets: photometric observations of 5 Vul
Monthly Notices of the Royal Astronomical Society, 2023 The presence of minor bodies in exoplanetary systems is in most cases inferred through infra-red excesses, with the exception of exocomets. Even if over 35 years have passed since the first detection of exocomets around beta Pic, only ~ 25 systems are ...

Two families of exocomets in the β Pictoris system
Nature, 2014 International audienceThe young planetary system surrounding the star β Pictoris harbours active minor bodies. These asteroids and comets produce a large amount of dust and gas through collisions and evaporation, as happened early in the history of our ...

Transiting exocomets detected in broadband light by TESS in the β Pictoris system [PDF]
Astronomy and Astrophysics, 2019 Aims We search for signs of falling evaporating bodies (FEBs, also known as exocomets) in photometric time series obtained for β Pictoris after fitting and removing its δ Scuti-type pulsation frequencies.
