Mass loss rates of a sample of irregular and semiregular M-type AGB-variables [PDF]

, 2002
We have determined mass loss rates and gas expansion velocities for a sample of 69 M-type irregular (IRV; 22 objects) and semiregular (SRV; 47 objects) AGB-variables using a radiative transfer code to model their circumstellar CO radio line emission.

Initial Stages of AZ31B Magnesium Alloy Degradation in Ringer’s Solution: Interpretation of EIS, Mass Loss, Hydrogen Evolution Data and Scanning Electron Microscopy Observations

Metals, 2018
The initial stages of corrosion of AZ31B magnesium alloy, immersed in Ringer’s solution at 37 °C body temperature for four days, have been evaluated by independent gravimetric and chemical methods and through electrochemical impedance ...

Multi-Planet Destabilisation and Escape in Post-Main Sequence Systems [PDF]

, 2013
Discoveries of exoplanets orbiting evolved stars motivate critical examinations of the dynamics of $N$-body systems with mass loss. Multi-planet evolved systems are particularly complex because of the mutual interactions between the planets.

Conservation of minimally processed green pepper conditioned in different plastic packages

Pesquisa Agropecuária Tropical, 2012
Minimal processing of vegetables adds value to the final product for increasing its convenience and reducing the time to prepare meals. This study aimed to evaluate the conservation of minimally processed green peppers 'Konan R', sliced and conditioned ...

Mass loss and stellar superwinds [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017
Mass loss bridges the gap between massive stars and supernovae (SNe) in two major ways: (i) theoretically, it is the amount of mass lost that determines the mass of the star prior to explosion and (ii) observations of the circumstellar material around SNe may teach us the type of progenitor that made the SN.

Mass loss rates and the mass evolution of star clusters

, 2010
We describe the interplay between stellar evolution and dynamical mass loss of evolving star clusters, based on the principles of stellar evolution and cluster dynamics and on a grid of N-body simulations of cluster models.

Winds from stripped low-mass Helium stars and Wolf-Rayet stars [PDF]

, 2017
We present mass-loss predictions from Monte Carlo radiative transfer models for helium (He) stars as a function of stellar mass, down to 2 Msun. Our study includes both massive Wolf-Rayet (WR) stars and low-mass He stars that have lost their envelope ...

Biodegradability and Cavitation Erosion Behavior of Some Zinc Alloys from the System ZnCuMg

Metals
This paper presents experimental results regarding the development of new alloys from the binary ZnCu and ternary ZnCuMg systems. The alloys had controlled chemical compositions and were annealed at 300 °C and 400 °C, with holding times of 5 h and 10 h ...

Radio emission from the massive stars in the Galactic Super Star Cluster Westerlund 1 [PDF]

, 2009
Current mass-loss rate estimates imply that main sequence winds are not sufficient to strip away the H-rich envelope to yield Wolf-Rayet (WR) stars. The rich transitional population of Westerlund 1 (Wd 1) provides an ideal laboratory to observe mass-loss

Mass-loss rates for transiting exoplanets

, 2011
Exoplanets at small orbital distances from their host stars are submitted to intense levels of energetic radiations, X-rays and extreme ultraviolet (EUV).
