The outflows from comets in orbit around G-type main-sequence stars can be detected when they produce transient OH absorption lines in the spectrum near 3100 Å of the host star. There is only about a 3 × 10-8 probability of detecting an analog to comet Hale-Bopp orbiting an analog to the Sun. However, for young solar-type stars with very large numbers of comets, possibly delivering water to terrestrial planets, there is as much as a 1% chance that any sufficiently sensitive, randomly timed… 
Direct Detection of Extrasolar Comets Is Possible
The dust tails of comets similar to Hale-Bopp can scatter as much optical sunlight as does the Earth. Space-based observatories such as the Terrestrial Planet Finder or Darwin that will detect
How to design a planetary system for different scattering outcomes: giant impact sweet spot, maximising exocomets, scattered disks
This paper considers the dynamics of scattering of planetesimals or planetary embryos by a planet on a circumstellar orbit. We classify six regions in the planet's mass versus semimajor axis
Future Exoplanet Research: Science Questions and How to Address Them
Some science questions which should go beyond standard improvements in exoplanetology and how to address them are outlined.


Evolution and detectability of comet clouds during post-main-sequence stellar evolution
Stars leaving the main sequence enter a luminous phase, during which circumstellar comet disks would be partially evaporated. Such a process could explain some observations of water masers and
On the number of comets around other single stars
It is shown how to obtain interesting limits on the number of comets in orbit around other single stars in clouds similar to the one present in our own solar system. The number of comets around white
Dusty Circumstellar Disks
▪ Abstract Dusty circumstellar disks in orbit around main-sequence stars were discovered in 1983 by the infrared astronomical satellite. It was the first time material that was not another star had
Discovery of water vapour around IRC+10216 as evidence for comets orbiting another star
The observation of circumstellar water vapour around the ageing carbon star IRC+10216 is reported; water is not expected in measurable quantities around such a star; the only plausible explanation for this water is that the recent evolution of IRC+ 10216 is causing the vaporization of a collection of orbiting icy bodies.
A 25 micron search for Vega-like disks around main-sequence stars with ISO
We present an ISO 25 m photometric survey of a sample of 81 nearby main-sequence stars in order to determine the incidence of \warm" dust disks. All stars were detected by ISO. We used an empirical
When a main sequence star evolves into a red giant and its Kuiper Belt objects (KBOs) reach a temperature of ~170 K, the dust released during the rapid ice sublimation of these cometary bodies may
Inner part observation of theβ pictoris disk
The inner regions of the circumstellar disk aroundβ Pictoris might be dust-free due to a possible planet which may have cleared up dust particles. We present a new observational technique based on
Rapid collisional evolution of comets during the formation of the Oort cloud
It appears that collisions will prevent most comets escaping from most locations in the region of the giant planets until the disk mass there declines sufficiently that the dynamical ejection timescale is shorter than the collisional lifetime.
Submillimeter and near-infrared images of cool dusty debris disks and rings suggest the existence of unseen planets. At dusty but nonimaged stars, semimajor axes of associated planets can be
Water Vapor in Carbon-rich Asymptotic Giant Branch Stars from the Vaporization of Icy Orbiting Bodies
We argue that the presence of water vapor in the circumstellar outflow of a carbon-rich asymptotic giant branch (AGB) star is potentially a distinctive signature of extrasolar cometary systems.
