The Impacts of D/Shoemaker-Levy 9 and Bioastronomy
The impacts of comet D/Shoemaker-Levy 9 into Jupiter provided the first chance to actually observe the effects which may be important in causing mass extinctions. The widely predicted global deposition of dust, leading to the phenomena associated with 'nuclear winter', was readily observed, although Jupiter's internal heat source causes a different response deep in the atmosphere than occurs on...
متن کاملAtmospheric gravity waves from the impact of Shoemaker - Levy 9 with Jupiter comet
We study the effect of the Jovian water cloud on internal gravity waves generated by the impact of comet SL9. Vertical structure follows Voyager data to the 1-bar level, a moist adiabat from 1 to 5 bars, and a dry adiabat below the 5-bar level. The waves are trapped in the moist layer and propagate horizontally. Their speed is related to the vertical integral of the Brunt-V•is•l& frequency, and...
متن کاملObservation of shoemaker-levy impacts by the galileo photopolarimeter radiometer.
The Galileo Photopolarimeter Radiometer experiment made direct photometric observations at 678 and 945 nanometers of several comet Shoemaker-Levy 9 fragments impacting with Jupiter. Initial flashes occurred at (fragment G) 18 July 1994 07:33:32, (H) 18 July 19:31:58, (L) 19 July 22:16:48, and (Q1) 20 July 20:13:52 [equivalent universal time coordinated (UTC) observed at Earth], with relative pe...
متن کاملCarbon Monoxide in Jupiter after Comet Shoemaker–Levy 9
for roughly half the mass. In high-temperature shocks, most of the O is converted to CO (Zahnle and MacLow Observations of the carbon monoxide fundamental vibration–rotation band near 4.7 mm before and after the impacts 1995), making CO one of the more abundant products of of the fragments of Comet Shoemaker–Levy 9 showed no dea large impact. tectable changes in the R5 and R7 lines, with one po...
متن کاملShoemaker-levy 9 Impact Modeling: I. High-resolution 3d Bolides
We have run high-resolution, three-dimensional, hydrodynamic simulations of the impact of comet Shoemaker-Levy 9 into the atmosphere of Jupiter. We find that the energy deposition profile is largely similar to the previous two-dimensional calculations of Mac Low & Zahnle, though perhaps somewhat broader in the range of height over which the energy is deposited. As with similar calculations for ...
