The transition mass-loss rate: Calibrating the role of line-driven winds in massive star evolution
Astrophysical Journal Letters, 2012 A debate has arisen regarding the importance of stationary versus eruptive mass loss for massive star evolution. The reason is that stellar winds have been found to be clumped, which results in the reduction of unclumped empirical mass-loss rates.

Mass-loss rates for transiting exoplanets [PDF]
Astronomy & Astrophysics, 2011 Exoplanets at small orbital distances from their host stars are submitted to intense levels of energetic radiations, X-rays and extreme ultraviolet (EUV). Depending on the masses and densities of the planets and on the atmospheric heating efficiencies, the stellar energetic inputs can lead to atmospheric mass loss.

Mass loss rate determination of southern OB stars [PDF]
Astronomy & Astrophysics, 2001 A sample of OB stars (eleven Of, one O and one B supergiant) has been surveyed with the Australia Telescope Compact Array at 4.8 and 8.64 GHz with a resolution of 2'' -- 4''. Five stars were detected; three of them have negative spectral indices, consistent with non-thermal emission, and two have positive indices.

The evolution of red supergiant mass-loss rates [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 The fate of massive stars with initial masses >8M$_\odot$ depends largely on the mass-loss rate (\mdot ) in the end stages of their lives. Red supergiants (RSGs) are the direct progenitors to Type II-P core collapse supernovae (SN), but there is uncertainty regarding the scale and impact of any mass-loss during this phase.

Mass Loss Rates of Three Comets [PDF]
Symposium - International Astronomical Union, 1992 Emission features of C2, C3, CN, and dust in Comets Thiele (1985m), Hartley-Good (1985l), and Giacobini-Zinner (1984e) have been analyzed and their mass loss rates of about 0.5, 1.1, and 0.8 Mg s−1 have been determined.
