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…
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…
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…
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…
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…
