A Census of the β Pic Moving Group and Other Nearby Associations with Gaia

The Astronomical Journal
I have used the third data release of the Gaia mission to improve the reliability and completeness of membership samples in the β Pic moving group (BPMG) and other nearby associations with ages of 20–50 Myr (Sco Body, Carina, Columba, χ ^1 For, Tuc-Hor ...

Color Gradients Within Globular Clusters: Restricted Numerical Simulation [PDF]

Journal of Astronomy and Space Sciences, 1997
The results of a restricted numerical simulation for the color gradients within globular clusters have been presented. The standard luminosity function of M3 and Salpeter's initial mass functions were used to generate model clusters as a fundamental ...

Suppressed Cosmic-Ray Energy Densities in Molecular Clouds from Streaming Instability-regulated Transport

The Astrophysical Journal
Cosmic rays (CRs) are the primary driver of ionization in star-forming molecular clouds (MCs). Despite their potential impacts on gas dynamics and chemistry, no simulations of star cluster formation following the creation of individual stars have ...

Protostellar Cores in Sagittarius B2 N and M

The Astrophysical Journal
We present 500 and 700 au resolution 1 and 3 mm Atacama Large Millimeter/submillimeter Array observations, respectively, of protostellar cores in protoclusters Sagittarius B2 (Sgr B2) North (N) and Main (M), parts of the most actively star-forming cloud ...

Nebular and Nonthermal Radio Emissions for Young Stellar Populations with PARSEC v1.2s

The Astrophysical Journal
In this paper, we compute, by means of the recently and thoroughly updated PARSE v1.2 s database of stellar nonrotating evolutionary tracks, the integrated stellar spectra, the ionizing photon budget, and the supernovae rates of young simple stellar ...
