The Physical Properties of the SVS 13 Protobinary System: Two Circumstellar Disks and a Spiraling Circumbinary Disk in the Making
Ana K. Diaz-Rodriguez, Guillem Anglada, Guillermo Blázquez-Calero +13
We present VLA and ALMA observations of the close (0.3" = 90 au separation) protobinary system SVS 13. We detect two small circumstellar disks (radii 12 and 9 au in dus…
Numerical simulations of the 1840s great eruption of Carinae: I. Revisiting the explosion scenario
R. F. González, Luis A. Zapata, A. C. Raga +3
In this work, we present new two-dimensional hydrodynamical simulations of the major eruption of Car in the 1840s, which resulted in the formation of a bipolar nebula that is c…
W51North: A protocluster emerging out of a thermally inhibited fragmenting cloud
Mengyao Tang, Aina Palau, Luis A. Zapata +1
The fragmentation process in massive star-forming regions is one of the contemporary problems in astrophysics, and several physical processes have been proposed to control the frag…
Magnetic Fields in Massive Star-Forming Regions (MagMaR) II. Tomography Through Dust and Molecular Line Polarization in NGC 6334I(N)
Paulo C. Cortes, Patricio Sanhueza, Martin Houde +13
Here, we report ALMA detections of polarized emission from dust, CS(), and CS() toward the high-mass star-forming region NGC6334I(N). A…
Gravity Driven Magnetic Field at ~1000 au Scales in High-mass Star Formation
Patricio Sanhueza, Josep Miquel Girart, Marco Padovani +20
A full understanding of high-mass star formation requires the study of one of the most elusive components of the energy balance in the interstellar medium: magnetic fields. We repo…
Explosive ejections generated by gravitational interactions
Pedro Ruben Rivera-Ortiz, Ary Rodríguez-González, Jorge Cantó +1
During the fragmentation and collapse of a molecular cloud, it is expected to have close encounters between (proto)stellar objects that can lead to the ejection of a fraction of th…
