Interacting jets from binary protostars [PDF]
Astronomy & Astrophysics, 2007 We investigate potential models that could explain why multiple proto-stellar systems predominantly show single jets. During their formation, stars most frequently produce energetic outflows and jets. However, binary jets have only been observed in a very small number of systems. We model numerically 3D binary jets for various outflow parameters.

Lifetime of the Outer Solar System Nebula From Carbonaceous Chondrites
Journal of Geophysical Research: Planets, Volume 127, Issue 7, July 2022., 2022 Abstract The evolution and lifetime of protoplanetary disks (PPDs) play a central role in the formation and architecture of planetary systems. Astronomical observations suggest that PPDs evolve in two timescales, accreting onto the star for up to several million years (Myr) followed by gas dissipation within ≲1 Myr. Because solar nebula magnetic fields

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 At present, the health monitoring system of world sports events uses the system's on‐site information or periodic test information to evaluate the health of the system. In order to make the data more accurate, the application of cloud computing is necessary.

What Can Meteorites Tell Us About the Formation of Jupiter?
AGU Advances, Volume 2, Issue 2, June 2021., 2021 Abstract Gas giants like Jupiter are a fundamental component of planetary systems, but how they formed has been uncertain. Here we discuss how paleomagnetic records in meteorites of the solar nebula may tell us about Jupiter's final growth stage. We suggest that under certain testable assumptions, the meteorite data indicate that proto‐Jupiter grew ...

3D Radiation-hydrodynamic Simulations Resolving Interior of Rapidly Accreting Primordial Protostar
The Astrophysical Journal, 2023 Direct collapse of supermassive stars is a possible pathway to form supermassive black hole seeds at high redshifts. Whereas previous three-dimensional (3D) simulations demonstrate that supermassive stars form via rapid mass accretion, those resolving ...

The Astrophysical Journal Letters, 2023 Transferring a significant fraction of the magnetic flux from a dense cloud core is essential in the star formation process. A ringlike structure produced by magnetic flux loss has been predicted theoretically, but no observational identification has ...

The Formation of Population III Stars in Gas Accretion Stage: Effects of Magnetic Fields [PDF]
, 2013 The formation of Population III stars is investigated using resistive magnetohydrodynamic simulations. Starting from a magnetized primordial prestellar cloud, we calculate the cloud evolution several hundreds of years after first protostar formation ...
