Scale-dependent surface and volume density properties of filaments in molecular clouds
Guo-Yin Zhang, Alexander Men'shchikov, Jin-Zeng Li
We present a systematic analysis of scale-dependent properties of filamentary structures in seven nearby molecular clouds Taurus, Ophiuchus, Perseus, Orion A, California, IC 51…
Dense cores and filaments in M16: Enhanced formation efficiency in the stellar feedback-driven shell
Nageen Pervaiz, Guo-Yin Zhang, Alexander Men'shchikov +1
We present a comprehensive analysis of dense cores and filamentary structures in the M16 Eagle Nebula using high-resolution () surface density and temperature…
ALMA-IMF XXII. Role of core subfragmentation in the IMF origin: Hierarchical fragmentation cascade and CMF in W43-MM1
F. Motte, N. Le Nestour, R. Veyry +29
We aim to predict how the currently observed top-heavy CMF in the massive protocluster W43-MM1 evolves due to core subfragmentation. We used getsf to extract sources in 5 ALMA imag…
A Salpeter-like filament linear density function across nearby molecular clouds
Guo-Yin Zhang, Alexander Men'shchikov, Jin-Zeng Li
The high-mass slope of the stellar initial mass function (IMF), first measured by Salpeter in 1955, appears nearly universal across star-forming environments, yet its physical orig…
Deriving volume density profiles of filaments from observed surface densities
Alexander Men'shchikov, Guo-Yin Zhang
Accurate characterization of filamentary structures in star-forming clouds is essential for understanding star formation. Traditional methods fit observed surface density profiles…
AGB and Post-AGB Evolution: Structural and Chemical Changes
T. Bloecker, R. Osterbart, G. Weigelt +2
Structural and chemical changes during the AGB and post-AGB evolution are discussed with respect to two recent observational and theoretical findings. On the one hand, high-resolut…
