The calculation of Afρ and mass loss rate for comets

Icarus, 2012
Abstract Ab initio calculations of Afρ are presented using Mie scattering theory and a Direct Simulation Monte Carlo (DSMC) dust outflow model in support of the Rosetta mission and its target 67P/Churyumov-Gerasimenko (CG). These calculations are performed for particle sizes ranging from 0.010 μm to 1.0 cm.

Mass loss and the Eddington parameter: a new mass-loss recipe for hot and massive stars [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
Mass loss through stellar winds plays a dominant role in the evolution of massive stars. In particular, the mass-loss rates of very massive stars (⁠>100M⊙⁠) are highly uncertain.

Critical heat flux and mass loss rate for extinction of flaming combustion of timber

Fire Safety Journal, 2017
The critical mass loss rate and critical heat flux for self-extinction of flaming combustion during steady-state burning of timber was measured in this study for a range of timber species. A vertical mass loss calorimeter was used to provide the external

Quantitative Results on AGB Mass-Loss Rates

, 2007
We present new mass-loss rates for AGB stars derived from fitting circumstellar dust models to the spectral energy distributions from 1 to 35 mum of 26 LMC stars and 14 SMC stars. It is found that for pulsation periods greater than 500 days, there is a very tight correlation of mass-loss rate with pulsation period, but for shorter periods there is a ...

Mass Loss Rates of Fasting Polar Bears

Physiological and Biochemical Zoology, 2016
Polar bears (Ursus maritimus) have adapted to an annual cyclic regime of feeding and fasting, which is extreme in seasonal sea ice regions of the Arctic. As a consequence of climate change, sea ice breakup has become earlier and the duration of the open-water period through which polar bears must rely on fat reserves has increased.

Mass-Loss Rate for MF Resin Microspheres

IEEE Transactions on Plasma Science, 2004
This paper deals with the influence of experimental conditions on properties of melamine formaldehyde resin particles. Motivation for this study was the fact that many laboratories and experimenters use these particles as samples for dust plasma investigations.

The use of body mass loss to estimate metabolic rate in birds

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2011
During starvation, energy production occurs at the expense of body reserve utilisation which results in body mass loss. Knowing the role of the fuels involved in this body mass loss, along with their energy density, can allow an energy equivalent of mass loss to be calculated. Therefore, it is possible to determine daily energy expenditure (DEE) if two
