The effects of fly-bys on planetary systems
... More common, however, is that fly-bys only perturb the orbits of planets, sometimes leaving the system in an unstable state. Over time-scales of a few million to several hundred million years after the fly-by, this perturbation can trigger planet-planet scatterings, leading to the ejection of one or ...

Survival of icy grains in debris discs
... For a constant grain temperature, the yield increases rapidly with irradiation dose and reaches a plateau value for doses higher than ∼3 × 1018 photons/cm2 (Westley et al. 1995). This plateau value is on the order of few × 10−3 at T = 35−100 K. The obtained temperature dependence is relatively weak, ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
