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 ...

The Power of SOFIA/FORCAST in Estimating Internal Luminosities of Low Mass Class 0/I Protostars [PDF]
, 2017 With the Stratospheric Observatory for Infrared Astronomy (SOFIA) routinely operating science flights, we demonstrate that observations with the Faint Object infraRed CAmera for the SOFIA Telescope (FORCAST) can provide reliable estimates of the internal

Episodic excursions of low-mass protostars on the Hertzsprung-Russell diagram [PDF]
, 2018 Following our recent work devoted to the effect of accretion on the pre-main-sequence evolution of low-mass stars, we perform a detailed analysis of episodic excursions of low-mass protostars in the Hertzsprung-Russell (H-R) diagram triggered by strong ...
