As with the scalar fields, there are no zero temperature solutions. The result was that the field could not support any of the five spacetimes for realistic values of the curvature coupling constant between the scalar field and gravity. Determined the evolutionary behavior of a rotating black hole which is emitting massless scalar fields alone or a mixture of the known fields along with the massless scalar field. It was found in the pure massless scalar field case that the black hole would not lose all of its angular momentum, contrary to the standard view of black hole evaporation. Began to calculate an analytic expression for the value of the stress energy tensor of the electromagnetic field in a static, spherically symmetric spacetime.
Work is unfinished as yet.
Investigated the possibility of semiclassical black hole remnants at the endpoint of black hole evaporation for holes surrounded by massive and massless scalar fields. Determined that for the most realistic values of the curvature coupling constant that zero temperature black holes aren't allowed solutions. In addition to isoprene concentration, temperature and humidity were also monitored. Outfitted a van with a gas chromatograph, leaf cuvette system, and reduction detector for on-site sampling. Maintained approximately 40 aspen and eucalyptus trees in a greenhouse for use as samples for isoprene study.
