What Can Meteorites Tell Us About the Formation of Jupiter?

open access: yesAGU 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 ...

ON THE DISTRIBUTION OF PROTOSTAR MASSES [PDF]

open access: yesThe Astrophysical Journal, 2009
The distribution of protostar masses is studied for core-environment systems whose duration of infall follows a waiting-time distribution. Each core-environment system has a continuous density profile with no barrier to mass flow. The core is an isothermal sphere and the environment is a filament, a layer, or a uniform medium.

MASERS AS TRACERS OF ANGULAR MOMENTUM IN MOLECULAR OUTFLOWS

open access: yesTecnociencia, 2023
The dissipation of angular momentum of collapsing molecular cores is a key component in the formation of stars. Previous observations have reported that highly collimated protostellar jets can remove angular momentum from low-mass protostars.

Protostellar jets: A statistical view with the CALYPSO IRAM-PdBI survey [PDF]

open access: yesEPJ Web of Conferences, 2022
In the context of the CALYPSO IRAM-PdBI Lai•ge Program we performed the first statistical survey of protostellar jets by analysing molecular emission in a sample of 21 protostars covering a broad range of internal luminosities (Lint from 0.035 L⊙ to 47 L⊙

Merger Conditions of Population III Protostar Binaries

open access: yesThe Astrophysical Journal, 2023
Massive close binary stars with extremely small separations have been observed, and they are possible progenitors of gravitational-wave sources. The evolution of massive binaries in the protostellar accretion stage is key to understanding their formation

The Mass Accretion Rate and Stellar Properties in Class I Protostars

open access: yesThe Astrophysical Journal, 2023
Stars collect most of their mass during the protostellar stage, yet the accretion luminosity and stellar parameters, which are needed to compute the mass accretion rate, are poorly constrained for the youngest sources.

Observations of phosphorus-bearing molecules in the interstellar medium

open access: yesFrontiers in Astronomy and Space Sciences
The chemistry of phosphorus (31P) in space is particularly significant due to the key role it plays in biochemistry on Earth. Utilising radio and infrared spectroscopic observations, several key phosphorus-containing molecules have been detected in ...
