Cloud-cloud collision as origin of the G31.41+0.31 massive protocluster
M. T. Beltrán, V. M. Rivilla, M. S. N. Kumar +2
The G31.41+0.31 (G31) hot molecular core (HMC) is a high-mass protocluster showing accelerated infall and rotational spin-up that is well studied at high-angular resolution. To com…
The sharp ALMA view of infall and outflow in the massive protocluster G31.41+0.31
M. T. Beltrán, V. M. Rivilla, R. Cesaroni +15
Context. To better understand the formation of high-mass stars, it is fundamental to investigate how matter accretes onto young massive stars, how it is ejected, and how all this d…
Filament coalescence and hub structure in MonR2: Implications to massive star and cluster formation
M. S. N. Kumar, D. Arzoumanian, A. Men'shchikov +3
Here we study the MonR2 star forming region, which has a rich network of filaments joining in a star cluster forming hub, aiming at understanding the hub structure and to examine t…
Fragmentation in the massive G31.41+0.31 protocluster
M. T. Beltrán, V. M. Rivilla, R. Cesaroni +18
Context. ALMA observations at 1.4 mm and 0.2'' (750au) angular resolution of the Main core in the high-mass star forming region G31.41+0.31 have revealed a puzzling scenario: on th…
Unifying low and high mass star formation through density amplified hubs of filaments
M. S. N. Kumar, P. Palmeirim, D. Arzoumanian +1
Context: Star formation takes place in giant molecular clouds, resulting in mass-segregated young stellar clusters composed of Sun-like stars, brown dwarves, and massive O-type(50-…
A necklace of dense cores in the high-mass star forming region G35.20-0.74N: ALMA observations
Á. Sánchez-Monge, M. T. Beltrán, R. Cesaroni +13
The present study aims at characterizing the massive star forming region G35.20N, which is found associated with at least one massive outflow and contains multiple dense cores, one…
