A perturbed parameter model ensemble to investigate Mt. Pinatubo's 1991 initial sulfur mass emission [PDF]
Atmospheric Chemistry and Physics, 2015 We have performed more than 300 atmospheric simulations of the 1991 Pinatubo eruption using the AER 2-D sulfate aerosol model to optimize the initial sulfur mass injection as a function of altitude, which in previous modeling studies has often been ...

The Initial Mass Function of GMCs
, 2004 The properties of GMCs in several Local Group galaxies are quantified and compared. It is found that the mass spectrum of GMCs varies from galaxy to galaxy. The variations are significant and do not appear to be the result of systematic uncertainties.

The Initial Mass Function of the Galactic Early-type Field Stars Based on the LAMOST Survey
The Astrophysical JournalResearch on the high-mass end of the initial mass function (IMF) has been limited due to a scarcity of samples. Recently, Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), as the most efficient spectroscopic telescope, has provided new ...

Variations of the stellar initial mass function in semi-analytical models: implications for the mass assembly and the chemical enrichment of galaxies in the GAEA model [PDF]
, 2016 In this work, we investigate the implications of the Integrated Galaxy-wide stellar Initial Mass Function (IGIMF) approach in the framework of the semi-analytic model GAEA (GAlaxy Evolution and Assembly), which features a detailed treatment of chemical ...

Intense Star Cluster Formation: Stellar Masses, the Mass Function, and the Fundamental Mass Scale
The Astrophysical Journal LettersWithin the birth environment of a massive globular cluster, the combination of a luminous young stellar population and a high column density induces a state in which the thermal optical depth and radiation pressure are both appreciable.

The Astrophysical Journal, 2023 The stellar initial mass function (IMF) is expressed by ϕ ( m ) ∝ m ^− ^α with the slope α , and known as a poorly constrained but very important function in studies of star and galaxy formation. There are no sensible observational constraints on the IMF

The Low-mass Population in the Young Cluster Stock 8: Stellar Properties and Initial Mass Function [PDF]
Astrophysical Journal, 2016 The evolution of H ii regions/supershells can trigger a new generation of stars/clusters at their peripheries, with environmental conditions that may affect the initial mass function, disk evolution, and star formation efficiency.
