I've found an estimation for interstellar electron density which ranges from $3.0 \times 10^4$ electrons per cubic meter (pcm), to $5.0 \times 10^4$ electrons pcm close to the galactic plane. However,...
One always reads and hears that CO is a good tracer for H2. How are they correlated? How can you deduce from the (measurable) CO the amount of the (unmeasurable) H2 in the ISM?
I've been looking for examples at how mass-loss rates are determined. I'm studying a circumstellar dust shell ejected from a Wolf-Rayet star. I have some parameters like, expansion velocity of the ...
I am reading some research papers on the model proposed to describe e.g. the interstellar medium. The interstellar medium, which is very rarefied, but its governing equations are based on the ...
