The Mass Function and Average Mass Loss Rate of Dark Matter Subhaloes [PDF]
Monthly Notices of the Royal Astronomical Society, 2005 We present a simple, semi-analytical model to compute the mass functions of dark matter subhaloes. The masses of subhaloes at their time of accretion are obtained from a standard merger tree. During the subsequent evolution, the subhaloes experience mass

Period -- mass-loss rate relation of Miras with and without technetium [PDF]
Astronomy & Astrophysics, 2013 Aims: We report the discovery that Mira variables with and without absorption lines of the element technetium (Tc) occupy two different regions in a diagram of near- to mid-infrared colour versus pulsation period.

The Population of Dark Matter Subhaloes: Mass Functions and Average Mass Loss Rates [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Using a cosmological N-Body simulation and a sample of re-simulated cluster-like haloes, we study the mass loss rates of dark matter subhaloes, and interpret the mass function of subhaloes at redshift zero in terms of the evolution of the mass function ...

Solar Cycle Variation of the Mass-loss Rate of Coronal Mass Ejections
The Astrophysical Journal Supplement SeriesCoronal mass ejections (CMEs) are known as the main drivers of the most severe space weather disturbances. Usually, the most severe geomagnetic storms are caused by massive and fast CMEs.

Bound on the rate of Bondi mass loss [PDF]
Physical Review D, 2021 To ensure the light (emitted far away from the source of gravity) can arrive at the null infinity of an asymptotically flat spacetime, it is shown that the rate of Bondi mass aspect has to satisfy some conditions. In Einstein gravity theory, we find the sufficient condition implies a bound on the Bondi mass $m$, i.e., $|\dot{m}|\leqslant 0.3820~c^3/G$.

Mass loss rates and the mass evolution of star clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 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. The cluster models have different initial masses, different orbits, including elliptical ones, and different initial density ...

Critical Rates of Stellar Mass Loss [PDF]
Symposium - International Astronomical Union, 1979 Many of the effects of mass loss on OB stars have now been explored. Mass loss will cause a star to be overluminous for its mass (though less luminous than a star of its original mass) and, for moderate mass-loss rates, the luminosity decreases at the same rate as the mass contained in the convective core decreases causing the main sequence lifetime to

Measuring Mass Loss Rates from Galactic Satellites [PDF]
International Astronomical Union Colloquium, 1999 Number count profiles of many Galactic and some extra-galactic satellite systems show evidence for associated stars beyond the cut-off in density that is identified as the point of tidal limitation (e.g. Irwin & Hatzidimitriou 1995, Grillmair et al. 1995).

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.
