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 ...

A triple protostar system formed via fragmentation of a gravitationally unstable disk [PDF]
Nature, 2016 Binary and multiple star systems are a frequent outcome of the star formation process and as a result almost half of all stars with masses similar to that of the Sun have at least one companion star.

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 ...

Ingredients for solar-like systems: protostar IRAS 16293-2422 B versus comet 67P/Churyumov–Gerasimenko [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Our modern day Solar System has 4.6 × 109 yr of evolution behind it with just a few relics of its birth conditions remaining. Comets are thought to be some of the most pristine tracers of the initial ingredients that were combined to produce the Earth ...

Magnetically regulated collapse in the B335 protostar? I. ALMA observations of the polarized dust emission [PDF]
, 2018 The role of the magnetic field during protostellar collapse is poorly constrained from an observational point of view, although it could be significant if we believe state-of-the-art models of protostellar formation.

Kinematics around the B335 protostar down to au scales [PDF]
Astronomy & Astrophysics, 2019 Context. The relationship between outflow launching and the formation of accretion disks around young stellar objects is still not entirely understood, which is why spectrally and spatially resolved observations are needed.

Disk Wind Feedback from High-mass Protostars. II. The Evolutionary Sequence
The Astrophysical Journal, 2023 Star formation is ubiquitously associated with the ejection of accretion-powered outflows that carve bipolar cavities through the infalling envelope. This feedback is expected to be important for regulating the efficiency of star formation from a natal ...

An Asymmetric Keplerian Disk Surrounding the O-type Protostar IRAS 16547−4247 [PDF]
Astrophysical Journal, 2019 For the past few decades, there has been great interest in determining if even the most massive stars in our galaxy (namely the spectral O-type stars) are formed in a similar manner as the low- and intermediate-mass stars, that is, through the presence ...
