Fe I in the β Pictoris circumstellar gas disk

, 2017
The young planetary system β Pictoris is surrounded by a circumstellar disk of dust and gas. Because both dust and gas have a lifetime shorter than the system age, they need to be replenished continuously.

The Transiting Exocomets of HD 172555

, 2016
While most attention has been garnered by searches for super-Jovian mass exo-planets the presence of minor bodies can be detected, at least through their dissociation products in suitably oriented systems.

Numerical simulations of exocomet transits: Insights from

In recent years, the topic of existence and exploration of exocomets has been gaining increasing attention. The asymmetrical decrease in the star’s brightness due to the passage of a comet-like object in front of the star was successfully predicted.

Upper limits on CN from exocomets transiting $\beta$ Pictoris

The young (23 Myr) nearby (19.4 pc) star $\beta$ Pictoris hosts an edge-on debris disk with two gas giant exoplanets in orbit around it. Many transient absorption features have been detected in the rotationally broadened stellar lines, which are thought to be the coma of infalling exocomets crossing the line of sight towards Earth. In the Solar System,

A Nomenclature for Individual Exocomets

Space Science Reviews
Abstract 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.

From exoplanets to exocomets

Journal of Physics: Conference Series, 2019
Abstract To date (June 2017), more than 3610 planets orbiting other stars than our Sun are known. We shall briefly review the main detection methods, together with some of the big surprises which arose since the discovery of the first exoplanet around a solar type star in 1995.
