Mass loss from hot massive stars
TL;DR: In this paper, the authors discuss various aspects of radiation-driven mass loss, both from the theoretical and the observational side, focusing on the winds from OB-stars, and discuss the problems of measuring mass loss rates from weak winds and the potential of the NIR Br α -line as a tool to enable a more precise quantification, and comment on physical explanations for mass-loss rates that are much lower than predicted by the standard model.

TL;DR: The distribution in Galactic latitude of the detected sources appears to be consistent with a scale height in the Galactic disk for the parent population smaller than 100 pc, consistent with expectations for supernova remnants and/or pulsar wind nebulae.

Stellar Radio Astronomy: Probing Stellar Atmospheres from Protostars to Giants
TL;DR: In this paper, a review summarizes the radio view of the atmospheres of non-degenerate stars, focusing on energy release physics in cool coronal stars, wind phenomenology, and synchrotron emission in many systems as well.

TL;DR: In this article, the radial stratification of the so-called clumping factor was analyzed for 19 Galactic O-type supergiants/giants, by combining their own and archival data for Hα, IR, mm and radio fluxes, and using approximate methods, calibrated to more sophisticated models.
