Outflow Interaction in Cep-E: Numerical Simulation and Observational Manifestation

A. Rodríguez-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…

Unveiling the collision between molecular outflows: observational evidence and hydrodynamic simulations

E. Cohen Arazi, P. F. Velázquez, M. E. Ortega +5

We present an unexplored scenario for interpreting the outflows in the EGO G338.92+0.55 (b) region (hereafter, EGO G338). Within this framework, we investigate the hypothesis that…

FAUST XXVII: The circumbinary disk and the outflow of the L 1551 IRS 5 binary system

Aurora Durán, Laurent Loinard, Pedro R. Rivera-Ortiz +21

Using continuum and line data obtained from the large ALMA program FAUST, we studied the structure of the protostellar binary system L1551 IRS5 at sc…

Gravitationally Induced Explosive Outflows

Pedro Ruben Rivera-Ortiz, Ary Rodríguez-González, Jorge Cantó +4

Over the past decade, there has been a significant increase in the reporting of extensive and luminous star-forming regions associated with explosive outflows. Nevertheless, there…

The arc-shaped radio source at the center of NGC 6334A: Is it a colliding wind region of two young massive stars or the bow shock of a runaway star?

Vanessa Yanza, Sergio A. Dzib, Aina Palau +4

New multi-wavelength Karl G. Jansky VLA observations of CKR02A, the compact radio source in the center of the compact HII region NGC 6334A, are presented. The observations were car…

Confirming the Explosive Dispersal Outflow in DR21 with ALMA

E. Guzmán Ccolque, M. Fernández López, L. A. Zapata +2

We present Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm continuum and CO(2-1) line emission observations toward the high-mass star formation region DR21. Five new con…

ALMA Observations of the Extraordinary Carina Pillars: A Complementary Sample

Geovanni Cortes-Rangel, Luis A. Zapata, Pedro R. Rivera-Ortiz +3

We present a study of six dusty and gaseous pillars (containing the HH 1004 and HH 1010 objects) and globules (that contain the HH 666, HH 900, HH 1006, and HH 1066 objects) locali…

Modelling the early mass-ejection in jet driven protostellar outflows. Lessons from Cep E

P. R. Rivera-Ortiz, A. de A. Schutzer, B. Lefloch +1

We have used the axisymmetric chemo-hydrodynamical code WALKIMYA-2D to numerically model and reproduce the physical and CO emission properties of the jet-driven outflow from the in…

Mass ejection and time variability in protostellar outflows: Cep E. SOLIS XVI

A. de A. Schutzer, P. R. Rivera-Ortiz, B. Lefloch +46

Protostellar jets are an important agent of star formation feedback, tightly connected with the mass-accretion process. The history of jet formation and mass-ejection provides cons…

A train of shocks at 3000 au scale? Exploring the clash of an expanding bubble into the NGC 1333 IRAS 4 region. SOLIS XIV

Marta De Simone, Claudio Codella, Cecilia Ceccarelli +10

There is evidence that the star formation process is linked to the intricate net of filaments in molecular clouds, which may be also due to gas compression from external triggers.…

Two-wind interactions in binaries with two orbiting giant stars

A. Castellanos-Ramírez, A. Rodríguez-González, Z. Meliani +3

Some red giant envelopes present spiral structures (seen either in dust scattered stellar continuum or in molecular line emission), the most striking example probably being AFGL 30…

HCN/HNC chemistry in shocks: a study of L1157-B1 with ASAI

B. Lefloch, G. Busquet, S. Viti +9

HCN and its isomer HNC play an important role in molecular cloud chemistry and the formation of more complex molecules. We investigate here the impact of protostellar shocks on the…

An orbital release model for the Orion BN/KL fingers

A. C. Raga, P. R. Rivera-Ortiz, A. Rodriguez-Gonzalez +1

We present a simple model in which the bullets that produce the "Orion fingers" (ejected by the BN/KL object) are interpreted as protoplanets or low mass protostars in orbit around…

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…

H mass-velocity relationship from 3D numerical simulations of jet-driven molecular outflows

Adriano Cerqueira, Bertrand Lefloch, Alejandro Esquivel +4

Previous numerical studies have shown that in protostellar outflows, the mass-velocity distribution can be well described by a broken power law . On the oth…

Confirming the Explosive Outflow in G5.89 with ALMA

Luis A. Zapata, Paul T. P. Ho, Manuel Fernández-López +9

The explosive molecular outflow detected decades ago in the Orion BN/KL region of massive star formation was considered to be a bizarre event. This belief was strengthened by the n…

The initial physical conditions of the Orion BN/KL fingers

Pedro Ruben Rivera-Ortiz, Ary Rodríguez-González, Liliana Hernández-Martínez +2

Orion BN/KL is an example of a poorly understood phenomena in star forming regions involving the close encounter of young stellar objects. The explosive structure, the great variet…

Numerical models for the dust in RCW 120

A. Rodríguez-González, Z. Meliani, M. Sánchez-Cruces +2

The interstellar bubble RCW 120 seen around a type O runaway star is driven by the stellar wind and the ionising radiation emitted by the star. The boundary between the stellar win…
