TRAO Survey of Nearby Filamentary Molecular Clouds, the Universal Nursery of Stars (TRAO-FUNS). III. Filaments and Dense Cores in the NGC 2068 and NGC 2071 Regions of Orion B

The Astrophysical Journal, 2023
We present the results of molecular line observations performed toward the NGC 2068 and NGC 2071 regions of the Orion B cloud as the TRAO-FUNS project to study the roles of the filamentary structure in the formation of dense cores and stars in the clouds.

Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material

Meteoritics &Planetary Science, Volume 60, Issue 5, Page 1073-1094, May 2025.
Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.

Possible link between the power spectrum of interstellar filaments and the origin of the prestellar core mass function [PDF]

Astronomy & Astrophysics, 2015
Two major features of the prestellar CMF are: 1) a broad peak below 1 Msun, presumably corresponding to a mean gravitational fragmentation scale, and 2) a characteristic power-law slope, very similar to the Salpeter slope of the stellar initial mass function (IMF) at the high-mass end.

When Magnetic Fields Sculpt the Sky: The Riegel–Crutcher Cloud in Optical Polarization

The Astrophysical Journal
Filamentary structures are ubiquitous in the interstellar medium, yet the extent to which magnetic fields influence the morphology of cold atomic gas remains an open question.

H i Self-absorption toward the Cygnus X North: From Atomic Filament to Molecular Filament

The Astrophysical Journal Letters, 2023
Using the H i self-absorption data from the Five-hundred-meter Aperture Spherical radio Telescope, we perform a study of the cold atomic gas in the Cygnus X North region.

Characterization of the Micro‐Morphology and Compositional Distribution of Chang'e‐5 Lunar Soil Mineral Surfaces Using TOF‐SIMS

Advanced Science, Volume 12, Issue 11, March 20, 2025.
Lunar soil samples from Chang'e 5 are characterized by high‐resolution time‐of‐flight secondary ion mass spectrometry, which revealed uncommon vesicle patterns that may not be observed via the conventional scanning electron microscope with energy dispersive X‐ray.

Interstellar filaments and the statistics of galactic HI [PDF]

, 2007
This paper presents a statistical explanation of filament formation in the galactic atomic hydrogen. We claim that even in the absence of dynamical factors the Gaussian field corresponding to the measured values of the spectrum of random density should ...

Magnetic Field of a Ring-like Molecular Cloud

The Astronomical Journal
We present a detailed study of the magnetic field structure in the G111 molecular cloud, a ring-like filamentary cloud within the NGC 7538 region. Our analysis combines multiwavelength polarization data and molecular-line observations to investigate the ...
