Sulfur-bearing molecules in a sample of active star-forming cores

R. D. Taboada, N. C. Martinez, S. Paron +3

Astrochemical processes involving sulfur are not yet well understood because cosmic sulfur reservoirs and the production pathways of sulfur-bearing species remain elusive. Addressi…

Revisiting G29.862-0.0044: a jet cavity disrupted by an outflow in a likely young stellar object wide binary system

S. Paron, N. C. Martinez, M. E. Ortega +4

A few years ago, we investigated MYSO G29.862-0.0044 (YSO-G29), an intriguing star-forming region at a distance of 6.2 kpc. Although the typical disc-jet scenario was proposed to e…

Sulfur-bearing molecules in a sample of early star-forming cores

N. C. Martinez, S. Paron, M. E. Ortega +5

The sulfur content in dense molecular regions of the interstellar medium is highly depleted in comparison to diffuse clouds. The reason of this phenomenon is unclear, thus it is ne…

The molecular environment of the pillar-like features in the HII region G46.5-0.2

S. Paron, M. Celis Peña, M. E. Ortega +3

At the interface of HII regions and molecular gas peculiar structures appear, some of them with pillar-like shapes. Understanding their origin is important for characterizing trigg…

HII region G46.5-0.2: the interplay between ionizing radiation, molecular gas and star formation

S. Paron, M. E. Ortega, G. Dubner +8

HII regions are particularly interesting because they can generate dense layers of gas and dust, elongated columns or pillars of gas pointing towards the ionizing sources, and come…
