The timing analysis of the environmental consequences shows that the seismic shaking could take only up to two minutes from the impact center to the larger distance at Bogota D.C, while the ejecta
arrival could take near six minutes (three times longer) and the air blast takes about 28 minutes (14 times longer) to arrive at the larger observation point.
(bolus and guano) of Indian flying foxes were collected by spreading a polythene sheet of 1 m x 1 m (length x width) under the roosting sites of P.
Over the years, and since the discovery of SN 1998bw, the bolometric properties (kinetic energy, [E.sub.K], ejecta
mass, [M.sub.ej], and nickel mass, [M.sub.Ni]) of the best-observed GRB-SNe have been determined by sophisticated numerical simulations (hydrodynamical models coupled with radiative transfer, RT, codes) [3,7, 36,47,48,107,110-119] and analytical modelling [10, 18, 31, 32, 40, 41, 43, 106, 120-122].
(2000) documented minerals with planar microstructures in the ejecta
of the Popigai structure.
Today, unfortunately, this area has been designated a national park and therefore is virtually closed to collecting; no quarrying is allowed, and consequently fresh ejecta
are no longer being uncovered.
Nonetheless, in the present study all species range up to the ejecta
layer (sample sm75-503), or to the highest level of the Maastrichtian.
They based the program around four environmental effects: thermal radiation, seismic shaking, ejecta
deposition and air blast.
Water column samples were processed in the same manner as ejecta
. The top 1 cm of sediment was sampled using a 5-cc syringe as a corer.
While fecal pellets are commonly used as an estimate of resource use (Thomas 1988) ejecta
pellets provided an even better estimate in this study for three reasons.
Gases and Condensed Products Detected From IR Spectra of Ejecta
From SMC Irradiated with, Excimer Laser Radiation at [approximately]500 mJ/[cm.sup.2].
To do this, new spectral synthesis methods need to be developed considering the necessary microphysical (ejecta
chemistry, r-process physics, time-dependent gas state) and macrophysical (3d radiation transport) processes to obtain sufficient accuracy.
Fortunately, about 10 times less ejecta
swirled around The Cow as compared to a typical stellar explosion.
