A NEW PRESCRIPTION FOR THE MASS-LOSS RATES OF WC AND WO STARS [PDF]
The Astrophysical Journal, 2016 ABSTRACT We present a new empirical prescription for the mass-loss rates of carbon- and oxygen-sequence Wolf–Rayet stars as a function of their luminosity, surface chemical composition, and initial metallicity. The new prescription is based on results of detailed spectral analyses of WC and WO stars and improves the often applied Nugis ...

TGA-FT-IR Analysis of Evolution of Oxygenated Organics by Isothermal Low-Temperature Decomposition of Rice Straw Hydrolysis Residue [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2023 The study presents a TGA-FT-IR analysis of low-temperature thermochemical transformations of Rice straw hydrolysis residue (RSHR). Isothermal decomposition of RSHR was carried out for 3 h, at decomposition temperatures of 200, 250, 300, and 350 oC.

Red Supergiants in M31 and M33. II. The Mass-loss Rate [PDF]
The Astrophysical Journal, 2021 Abstract Mass loss is an important activity for red supergiants (RSGs) and can influence their evolution and final fate. Previous estimations of mass-loss rates (MLRs) of RSGs exhibit significant dispersion due to differences in method and the incompleteness of samples.

ESTIMATE OF MASS LOSS RATE FROM ALGOL - TYPE SYSTEMS BASED ON RADIOFLUXES
Odessa Astronomical Publications, 2017 The estimates of the upper limit mass loss rate from Algol-type binaries based on observations at radio wavelengths match well the results obtained from the optical data. This mass loss rate suggests that Algol-type systems observed at radio wave lengths

MASS-LOSS RATES OF OH/IR STARS [PDF]
Journal of The Korean Astronomical Society, 2013 We compare mass-loss rates of OH/IR stars obtained from radio observations with those derived from the dust radiative transfer models and IR observations. We collect radio observational data of OH maser and CO line emission sources for a sample of 1533 OH/IR stars listed in Suh & Kwon (2011).

Accelerated glacier mass loss in the southeastern Tibetan Plateau since the 1970s
Advances in Climate Change Research, 2023 The southeastern Tibetan Plateau (SETP) is a region in High Mountain Asia with the most serious glacier mass loss. However, long-term and large regional-scale studies that estimate glacier mass balance in this area remain limited.

On the Equatorial Mass-Loss Rate of Be Stars [PDF]
International Astronomical Union Colloquium, 2002 AbstractWe numerically study the formation process of equatorial disks around isolated Be stars, using an SPH code. We find that the viscous decretion disk model naturally explains the observed disk formation episode of X Per, giving the equatorial mass-loss rate of several ×10−9 (ρ0/10−10 g cm−3) M⊙ yr−1, where ρ0 is the base density of the disk.

Relative rate of mass loss during heating separated into periods.
, 2013 M. hyalinus lost mass at a slower rate in the earlier, cooler period, but its rate of mass loss increased dramatically in the warmer period. C. lineosa’s mass loss rate remained relatively constant throughout the experiment (repeated measures, F1,114 ...
