Direct Detection of Extrasolar Comets Is Possible
@article{Jura2005DirectDO, title={Direct Detection of Extrasolar Comets Is Possible}, author={M. Jura}, journal={The Astronomical Journal}, year={2005}, volume={130}, pages={1261 - 1266} }
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 extrasolar terrestrial planets also will be able to detect extrasolar comets.

AN UPPER BOUND TO THE SPACE DENSITY OF INTERSTELLAR COMETS
- Physics, Geology
- 2011
Two well-studied white dwarfs with helium-dominated atmospheres (DBs) each possess less hydrogen than carried by a single average-mass comet. Plausibly, the wind rates from these stars are low enough…
REALISTIC DETECTABILITY OF CLOSE INTERSTELLAR COMETS
- Physics, Geology

The Age Dependence of the Detectability of Comets Orbiting Solar-Type Stars
- Physics, Geology
- 2005
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…
Evolution and detectability of comet clouds during post-main-sequence stellar evolution
- Physics, GeologyNature

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…

With the strong Compton Gamma-Ray Observatory/Burst and Transient Source Experiment (CGRO/BATSE) evidence that most gamma-ray bursts do not come from galactic neutron stars, models involving the…
On the number of comets around other single stars

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…
BETA PICTORIS: An Early Solar System?

Beta Pictoris ( Pic) is the best studied of the normal main-sequence stars surrounded by circumstellar dust disks. We review the status of Pic and its disk, and compare it with both the early and the…
Discovery of water vapour around IRC+10216 as evidence for comets orbiting another star
- Physics, GeologyNature
- 2001
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.

Dust particles observed in extrasolar planetary discs originate from undetectable km-sized bodies but this valuable information remains uninteresting if the theoretical link between grains and…
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.…
