WebApr 11, 2024 · The best-fitting, micrometeroid-dust-free, disequilibrium chemistry, patchy cloud model has the following parameters: effective temperature Teff=681 K with clouds (or without clouds, i.e. the grid temperature Tgrid = 900 K), surface gravity g = 1000 m/s2, sedimentation efficiency fsed = 10, vertical eddy diffusion coefficient Kzz = 103 cm2/s ... WebInterstellar dust has a size and structure similar to soot particles, and in the densest regions the dust may completely obscure the light of stars behind it, producing an absorption nebula, or dark nebula. Typical dust cloud sizes are about 10 pc, with representative masses of about 50 solar masses. Within these dusty regions, globules of ...

WebNow imagine that an interstellar dust cloud lies between us and SN 1994D. Suppose that the peak apparent visual magnitude would have been 11.3 if the cloud were not absorbing some of its light. Based on that unbiased value, what would the supernova's distance really be, in light-years? WebThe interstellar medium refers to the tenuous gas and dust that fills the void between stellar systems in galaxies.
