Abstract: | Free-space equilibrium temperatures for porous interstellar grains are computed for different dust sizes and are compared
to those expected for homogeneous normal grains for two material candidates: graphite and a lunar silicate. Relevant differences
are found with the former, but are essentially negligible with the latter. The results are discussed in terms of the different
optical properties produced by the porosity of the grains. The possible astrophysical implications of these findings are also
mentioned. |
