A nomenclature for individual exocomets

With recent observational advancements, exocomet studies have entered a new era: we have moved from an epoch where exocomets' signatures were analysed to identify their true nature to a new epoch where individual exocomets' detections are studied in detail to characterise the observed bodies. In this context, as with other astronomical objects such as exoplanets and minor bodies in the solar system, a nomenclature system is needed to uniquely identify any observed exocometary body. Here, after outlining the purpose of a nomenclature and its required characteristics, we review the information on exocomets that can be included in the nomenclature. Finally, we propose an exocomet nomenclature scheme to identify the individual exocomets that have been discovered or yet to be discovered. Examples of nomenclature names of a few archetypal exocomets are provided.

Alien Comets Swarm around Other Stars

In a cosmic dance beyond our solar system, alien comets are discovered to be swirling around distant stars, revealing a mesmerizing celestial phenomenon. These interstellar wanderers, known as "exocom...

Astronomers Announce Largest Collection Of Exocomets Found | Center for Astrophysics | Harvard & Smithsonian
"For the first time, astronomers have imaged dozens of belts around nearby stars where comets and tiny pebbles within them are orbiting.This result reveals regions around 74 stars spanning a wide range of ages – from those recently formed to others billions of years old – showing how comets play a role in the formation of stars and planetary systems."

Good morning, my friends!

We’re back at #ExSSV with some more #JWST results on beta Pictoris by Jens Kammerer.

beta Pic is a famous target in our field because it was the first system with a discovered disc - back in the days. Also: the system has #exocomets ☄️

Beta Pic b was the first planet discovered in the system using direct imaging. There’s also a second one.

Kammerer+ observed beta Pic with #JWST #MIRI 🤩 #ExSSV

Three Rare Exocomets Spotted In Orbit Around a Nearby Star | Digital Trends

Scientists have spotted three exocomets, or comets outside of our Solar System, in orbit around a bright young star called Beta Pictoris in the constellation of Pictor. They used NASA’s Transiting Exoplanets Survey Satellite (TESS) to capture detailed data about the amount of light being generated.
