SN 2009ip: constraints on the progenitor mass-loss rate [PDF]

, 2013
Some supernovae (SNe) show evidence for mass-loss events taking place prior to their explosions. Measuring their pre-outburst mass-loss rates provides essential information regarding the mechanisms that are responsible for these events.

A distributional approach to fragmentation equations [PDF]

, 2011
We consider a linear integro-di®erential equation that models multiple fragmentation with inherent mass-loss. A systematic procedure is presented for constructing a space of generalised functions Z0 in which initial-value problems involving singular ...

Crystallinity versus mass-loss rate in asymptotic giant branch stars [PDF]

, 2001
Infrared Space Observatory (ISO) observations have shown that O-rich Asymptotic Giant Branch (AGB) stars exhibit crystalline silicate features in their spectra only if their mass-loss rate is higher than a certain threshold value.

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.

Solar Cycle Variation of the Mass-loss Rate of Coronal Mass Ejections

The Astrophysical Journal Supplement Series
Coronal 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.

Fire Safety Characteristics of Pine Wood Under Low Pressure and Oxygen Enrichment

Fire
Oxygen enrichment at high altitudes indoors can be effective in meeting demand. However, the high oxygen environment inevitably brings about additional fire hazards, and the specific changes are still unclear.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Full-Scale Experimental Stand Development with HRR Determination from Mass Loss and CFD Model Validation

Fire
Accurate prediction of urban air quality during fire events is frequently limited by the lack of experimentally validated source terms. Current pollution dispersion models often rely on idealized input parameters that fail to capture the complex thermal ...
