Orbital Motions of Binaries in Orion South
Luis A. Zapata, Luis F. RodrÃguez
We present high-angular resolution () VLA and ALMA observations of Orion South separated by 15.52 years. The purpose of this study was to search for orbital m…
The DESIRED temperature-metallicity relations in star-forming regions: probing the Galactic radial and azimuthal metallicity distributions
I. Rafael MartÃnez-Hernández, J. Eduardo Méndez-Delgado, César Esteban +17
We analyse a sample of 225 star-forming regions from the DESIRED-E project, each with simultaneous determinations of the electron temperature from ionized nitrogen and oxygen, $T_{…
Outflow Interaction in Cep-E: Numerical Simulation and Observational Manifestation
A. RodrÃguez-González, P. R. Rivera-Ortiz, Z. Meliani +3
There is clear observational evidence that the main Class 0/I stages of the star formation process are associated with powerful collimated outflows (jets), which sometimes propagat…
ALMA-IMF XX: Core fragmentation in the W51 high-mass star-forming region
T. Yoo, A. Ginsburg, J. Braine +27
We present a study of core fragmentation in the W51-E and W51-IRS2 protoclusters in the W51 high-mass star-forming region. The identification of core fragmentation is achieved by t…
