What Can Meteorites Tell Us About the Formation of Jupiter?
AGU Advances, 2021 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.

X-Ray Emission from the Pre-Planetary Nebula Henize 3-1475 [PDF]
, 2003 We report the first detection of X-ray emission in a pre-planetary nebula, Hen 3-1475. Pre-planetary nebulae are rare objects in the short transition stage between the Asymptotic Giant Branch and planetary nebula evolutionary phases, and Hen 3-1475 ...

The magnetic field of the proto-planetary nebula candidate IRAS 19296+2227
, 2008 Context: Magnetic fields are thought to be one of the possible mechanisms responsible for shaping the generally spherical outflow of evolved stars into often aspherical planetary nebulae.

The planetary nebula Abell 48 and its [WN] nucleus [PDF]
, 2013 We have conducted a detailed multi-wavelength study of the peculiar nebula Abell 48 and its central star. We classify the nucleus as a helium-rich, hydr ogen-deficient star of type [WN4‐ 5].

Evolution of Terrestrial Planetary Bodies and Implications for Habitability
Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Confirmation of SBS 1150+599A As An Extremely Metal-Poor Planetary Nebula
, 2002 SBS 1150+599A is a blue stellar object at high galactic latitude discovered in the Second Byurakan Survey. New high-resolution images of SBS 1150+599A are presented, demonstrating that it is very likely to be an old planetary nebula in the galactic halo,

The planetary nebula population in the halo of M 87 [PDF]
, 2013 Aims. We investigate the diffuse light in the outer regions of the nearby elliptical galaxy M 87 in the Virgo cluster, in the transition region between galaxy halo and intracluster light (ICL). Methods. The diffuse light is traced using planetary nebulas

Geostandards and Geoanalytical Research, Volume 49, Issue 4, Page 737-750, December 2025.Key Points PEEK tubing has been observed to adsorb Pd and Pt ions, resulting in significantly reduced recoveries of Pd and Pt elements. HPA‐S provides a more effective dissolution for meteorite samples than Carius tube digestion, resulting in higher mass fractions for PGE.

Protracted Timescales for Nebular Processing of First-formed Solids in the Solar System
The Astrophysical Journal, 2023 The calcium–aluminum-rich inclusions (CAIs) from chondritic meteorites are the first solids formed in the solar system. Rim formation around CAIs marks a time period in early solar system history when CAIs existed as free-floating objects and had not yet
